It is + normally used with a TQTextStream or a TQDataStream. TQBuffer has an + associated TQByteArray which holds the buffer data. The size() of + the buffer is automatically adjusted as data is written. + + The constructor \c TQBuffer(TQByteArray) creates a TQBuffer using an + existing byte array. The byte array can also be set with + setBuffer(). Writing to the TQBuffer will modify the original byte + array because TQByteArray is \link shclass.html explicitly + shared.\endlink + + Use open() to open the buffer before use and to set the mode + (read-only, write-only, etc.). close() closes the buffer. The + buffer must be closed before reopening or calling setBuffer(). + + A common way to use TQBuffer is through \l TQDataStream or \l + TQTextStream, which have constructors that take a TQBuffer + parameter. For convenience, there are also TQDataStream and + TQTextStream constructors that take a TQByteArray parameter. These + constructors create and open an internal TQBuffer. + + Note that TQTextStream can also operate on a TQString (a Unicode + string); a TQBuffer cannot. + + You can also use TQBuffer directly through the standard TQIODevice + functions readBlock(), writeBlock() readLine(), at(), getch(), + putch() and ungetch(). + + \sa TQFile, TQDataStream, TQTextStream, TQByteArray, \link shclass.html Shared Classes\endlink +*/ + + +/*! + Constructs an empty buffer. +*/ + +TQBuffer::TQBuffer() +{ + setFlags( IO_Direct ); + a_inc = 16; // initial increment + a_len = 0; + ioIndex = 0; +} + + +/*! + Constructs a buffer that operates on \a buf. + + If you open the buffer in write mode (\c IO_WriteOnly or + \c IO_ReadWrite) and write something into the buffer, \a buf + will be modified. + + Example: + \code + TQCString str = "abc"; + TQBuffer b( str ); + b.open( IO_WriteOnly ); + b.at( 3 ); // position at the 4th character (the terminating \0) + b.writeBlock( "def", 4 ); // write "def" including the terminating \0 + b.close(); + // Now, str == "abcdef" with a terminating \0 + \endcode + + \sa setBuffer() +*/ + +TQBuffer::TQBuffer( TQByteArray buf ) : a(buf) +{ + setFlags( IO_Direct ); + a_len = a.size(); + a_inc = (a_len > 512) ? 512 : a_len; // initial increment + if ( a_inc < 16 ) + a_inc = 16; + ioIndex = 0; +} + +/*! + Destroys the buffer. +*/ + +TQBuffer::~TQBuffer() +{ +} + + +/*! + Replaces the buffer's contents with \a buf and returns TRUE. + + Does nothing (and returns FALSE) if isOpen() is TRUE. + + Note that if you open the buffer in write mode (\c IO_WriteOnly or + IO_ReadWrite) and write something into the buffer, \a buf is also + modified because TQByteArray is an explicitly shared class. + + \sa buffer(), open(), close() +*/ + +bool TQBuffer::setBuffer( TQByteArray buf ) +{ + if ( isOpen() ) { +#if defined(QT_CHECK_STATE) + qWarning( "TQBuffer::setBuffer: Buffer is open" ); +#endif + return FALSE; + } + a = buf; + a_len = a.size(); + a_inc = (a_len > 512) ? 512 : a_len; // initial increment + if ( a_inc < 16 ) + a_inc = 16; + ioIndex = 0; + return TRUE; +} + +/*! + \fn TQByteArray TQBuffer::buffer() const + + Returns this buffer's byte array. + + \sa setBuffer() +*/ + +/*! + \reimp + + Opens the buffer in mode \a m.

The component exported by the component server has to implement the + TQComponentRegistrationInterface. + + The static functions registerComponent() and unregisterComponent() register and unregister a single + component in the system component registry, and should be used when implementing the + \link TQComponentRegistrationInterface::registerComponents() registerCompontents() \endlink and + \link TQComponentRegistrationInterface::unregisterComponents() unregisterCompontents() \endlink functions + in the TQComponentRegistrationInterface. + + A component is registered using a UUID, but can additionally be registered with a name, version and + description. A component registered with a name and a version can be instantiated by client applications + using the name and specific version number, or the highest available version number for that component by + just using the name. A component that is registered calling + + \code + TQComponentFactory::registerComponent( TQUuid(...), filename, "MyProgram.Component", 1 ); + \endcode + + can be instantiated calling either: + + \code + TQComponentFactory::createInstance( TQUuid(...), IID_XYZ, (TQUnknownInterface**)&iface ); + \endcode + or + \code + TQComponentFactory::createInstance( "MyProgram.Component", IID_XYZ, (TQUnknownInterface**)&iface ); + \endcode + or + \code + TQComponentFactory::createInstance( "MyProgram.Component.1", IID_XYZ, (TQUnknownInterface**)&iface ); + \endcode + + The first and the last way will always instantiate exactly the component registered above, while + the second call might also return a later version of the same component. This allows smoother upgrading + of components, and is easier to use in application source code, but should only be used when new versions + of the component are guaranteed to work with the application. + + The component name can be anything, but should be unique on the system the component is being + installed on.

Since TQCString is a TQMemArray, it uses \link + shclass.html explicit sharing\endlink with a reference count. + + TQCString tries to behave like a more convenient \c{const char *}. + The price of doing this is that some algorithms will perform + badly. For example, append() is O(length()) since it scans for a + null terminator. Although you might use TQCString for text that is + never exposed to the user, for most purposes, and especially for + user-visible text, you should use TQString. TQString provides + implicit sharing, Unicode and other internationalization support, + and is well optimized. + + Note that for the TQCString methods that take a \c{const char *} + parameter the \c{const char *} must either be 0 (null) or not-null + and '\0' (NUL byte) terminated; otherwise the results are + undefined. + + A TQCString that has not been assigned to anything is \e null, i.e. + both the length and the data pointer is 0. A TQCString that + references the empty string ("", a single '\0' char) is \e empty. + Both null and empty TQCStrings are legal parameters to the methods. + Assigning \c{const char *} 0 to TQCString produces a null TQCString. + + The length() function returns the length of the string; resize() + resizes the string and truncate() truncates the string. A string + can be filled with a character using fill(). Strings can be left + or right padded with characters using leftJustify() and + rightJustify(). Characters, strings and regular expressions can be + searched for using find() and findRev(), and counted using + contains(). + + Strings and characters can be inserted with insert() and appended + with append(). A string can be prepended with prepend(). + Characters can be removed from the string with remove() and + replaced with replace(). + + Portions of a string can be extracted using left(), right() and + mid(). Whitespace can be removed using stripWhiteSpace() and + simplifyWhiteSpace(). Strings can be converted to uppercase or + lowercase with upper() and lower() respectively. + + Strings that contain numbers can be converted to numbers with + toShort(), toInt(), toLong(), toULong(), toFloat() and toDouble(). + Numbers can be converted to strings with setNum(). + + Many operators are overloaded to work with TQCStrings.

For example, a data stream that is written by a PC + under Windows can be read by a Sun SPARC running Solaris. + + You can also use a data stream to read/write \link #raw raw + unencoded binary data\endlink. If you want a "parsing" input + stream, see TQTextStream. + + The TQDataStream class implements the serialization of C++'s basic + data types, like \c char, \c short, \c int, \c char*, etc. + Serialization of more complex data is accomplished by breaking up + the data into primitive units. + + A data stream cooperates closely with a TQIODevice. A TQIODevice + represents an input/output medium one can read data from and write + data to. The TQFile class is an example of an IO device. + + Example (write binary data to a stream): + \code + TQFile file( "file.dat" ); + file.open( IO_WriteOnly ); + TQDataStream stream( &file ); // we will serialize the data into the file + stream << "the answer is"; // serialize a string + stream << (Q_INT32)42; // serialize an integer + \endcode + + Example (read binary data from a stream): + \code + TQFile file( "file.dat" ); + file.open( IO_ReadOnly ); + TQDataStream stream( &file ); // read the data serialized from the file + TQString str; + Q_INT32 a; + stream >> str >> a; // extract "the answer is" and 42 + \endcode + + Each item written to the stream is written in a predefined binary + format that varies depending on the item's type. Supported TQt + types include TQBrush, TQColor, TQDateTime, TQFont, TQPixmap, TQString, + TQVariant and many others. For the complete list of all TQt types + supporting data streaming see the \link datastreamformat.html + Format of the TQDataStream operators \endlink. + + For integers it is best to always cast to a TQt integer type for + writing, and to read back into the same TQt integer type. This + ensures that you get integers of the size you want and insulates + you from compiler and platform differences. + + To take one example, a \c char* string is written as a 32-bit + integer equal to the length of the string including the NUL byte + ('\0'), followed by all the characters of the string including the + NUL byte. When reading a \c char* string, 4 bytes are read to + create the 32-bit length value, then that many characters for the + \c char* string including the NUL are read. + + The initial IODevice is usually set in the constructor, but can be + changed with setDevice(). If you've reached the end of the data + (or if there is no IODevice set) atEnd() will return TRUE. + + If you want the data to be compatible with an earlier version of + TQt use setVersion(). + + If you want the data to be human-readable, e.g. for debugging, you + can set the data stream into printable data mode with + setPrintableData(). The data is then written slower, in a bloated + but human readable format. + + If you are producing a new binary data format, such as a file + format for documents created by your application, you could use a + TQDataStream to write the data in a portable format. Typically, you + would write a brief header containing a magic string and a version + number to give yourself room for future expansion. For example: + + \code + TQFile file( "file.xxx" ); + file.open( IO_WriteOnly ); + TQDataStream stream( &file ); + + // Write a header with a "magic number" and a version + stream << (Q_UINT32)0xA0B0C0D0; + stream << (Q_INT32)123; + + // Write the data + stream << [lots of interesting data] + \endcode + + Then read it in with: + + \code + TQFile file( "file.xxx" ); + file.open( IO_ReadOnly ); + TQDataStream stream( &file ); + + // Read and check the header + Q_UINT32 magic; + stream >> magic; + if ( magic != 0xA0B0C0D0 ) + return XXX_BAD_FILE_FORMAT; + + // Read the version + Q_INT32 version; + stream >> version; + if ( version < 100 ) + return XXX_BAD_FILE_TOO_OLD; + if ( version > 123 ) + return XXX_BAD_FILE_TOO_NEW; + if ( version <= 110 ) + stream.setVersion(1); + + // Read the data + stream >> [lots of interesting data]; + if ( version > 120 ) + stream >> [data new in XXX version 1.2]; + stream >> [other interesting data]; + \endcode + + You can select which byte order to use when serializing data. The + default setting is big endian (MSB first). Changing it to little + endian breaks the portability (unless the reader also changes to + little endian). We recommend keeping this setting unless you have + special retquirements. + + \target raw + \section1 Reading and writing raw binary data + + You may wish to read/write your own raw binary data to/from the + data stream directly. Data may be read from the stream into a + preallocated char* using readRawBytes(). Similarly data can be + written to the stream using writeRawBytes(). Notice that any + encoding/decoding of the data must be done by you. + + A similar pair of functions is readBytes() and writeBytes(). These + differ from their \e raw counterparts as follows: readBytes() + reads a Q_UINT32 which is taken to be the length of the data to be + read, then that number of bytes is read into the preallocated + char*; writeBytes() writes a Q_UINT32 containing the length of the + data, followed by the data. Notice that any encoding/decoding of + the data (apart from the length Q_UINT32) must be done by you. + + \sa TQTextStream TQVariant +*/ + +/*! + \enum TQDataStream::ByteOrder + + The byte order used for reading/writing the data. + + \value BigEndian the default + \value LittleEndian +*/ + + +/***************************************************************************** + TQDataStream member functions + *****************************************************************************/ + +#if defined(QT_CHECK_STATE) +#undef CHECK_STREAM_PRECOND +#define CHECK_STREAM_PRECOND if ( !dev ) { \ + qWarning( "TQDataStream: No device" ); \ + return *this; } +#else +#define CHECK_STREAM_PRECOND +#endif + +static int systemWordSize = 0; +static bool systemBigEndian; + +static const int DefaultStreamVersion = 6; +// ### On next version bump, TQPen::width() should not be restricted to 8-bit values. +// ### On next version bump, when streaming invalid TQVariants, just the type should +// be written, no "data" after it +// 6 is default in TQt 3.3 +// 5 is default in TQt 3.1 +// 4 is default in TQt 3.0 +// 3 is default in TQt 2.1 +// 2 is the TQt 2.0.x format +// 1 is the TQt 1.x format + +/*! + Constructs a data stream that has no IO device. + + \sa setDevice() +*/ + +TQDataStream::TQDataStream() +{ + if ( systemWordSize == 0 ) // get system features + qSysInfo( &systemWordSize, &systemBigEndian ); + dev = 0; // no device set + owndev = FALSE; + byteorder = BigEndian; // default byte order + printable = FALSE; + ver = DefaultStreamVersion; + noswap = systemBigEndian; +} + +/*! + Constructs a data stream that uses the IO device \a d. + + \warning If you use TQSocket or TQSocketDevice as the IO device \a d + for reading data, you must make sure that enough data is available + on the socket for the operation to successfully proceed; + TQDataStream does not have any means to handle or recover from + short-reads. + + \sa setDevice(), device() +*/ + +TQDataStream::TQDataStream( TQIODevice *d ) +{ + if ( systemWordSize == 0 ) // get system features + qSysInfo( &systemWordSize, &systemBigEndian ); + dev = d; // set device + owndev = FALSE; + byteorder = BigEndian; // default byte order + printable = FALSE; + ver = DefaultStreamVersion; + noswap = systemBigEndian; +} + +/*! + Constructs a data stream that operates on a byte array, \a a, + through an internal TQBuffer device.

It can read + the current date from the system clock. It provides functions for + comparing dates and for manipulating dates, e.g. by adding a + number of days or months or years. + + A TQDate object is typically created either by giving the year, + month and day numbers explicitly, or by using the static function + currentDate(), which creates a TQDate object containing the system + clock's date. An explicit date can also be set using setYMD(). The + fromString() function returns a TQDate given a string and a date + format which is used to interpret the date within the string. + + The year(), month(), and day() functions provide access to the + year, month, and day numbers. Also, dayOfWeek() and dayOfYear() + functions are provided. The same information is provided in + textual format by the toString(), shortDayName(), longDayName(), + shortMonthName() and longMonthName() functions. + + TQDate provides a full set of operators to compare two TQDate + objects where smaller means earlier and larger means later. + + You can increment (or decrement) a date by a given number of days + using addDays(). Similarly you can use addMonths() and addYears(). + The daysTo() function returns the number of days between two + dates. + + The daysInMonth() and daysInYear() functions return how many days + there are in this date's month and year, respectively. The + leapYear() function indicates whether this date is in a leap year. + + Note that TQDate should not be used for date calculations for dates + prior to the introduction of the Gregorian calendar. This calendar + was adopted by England from the 14<sup><small>th</small></sup> + September 1752 (hence this is the earliest valid TQDate), and + subsequently by most other Western countries, until 1923. + + The end of time is reached around the year 8000, by which time we + expect TQt to be obsolete. + + \sa TQTime TQDateTime TQDateEdit TQDateTimeEdit +*/ + +/*! + \enum TQt::DateFormat + + \value TextDate (default) TQt format + \value ISODate ISO 8601 extended format (YYYY-MM-DD, or with time, + YYYY-MM-DDTHH:MM:SS) + \value LocalDate locale dependent format +*/ + + +/*! + \enum TQt::TimeSpec + + \value LocalTime Locale dependent time (Timezones and Daylight Savings Time) + \value UTC Coordinated Universal Time, replaces Greenwich Time +*/ + +/*! + \fn TQDate::TQDate() + + Constructs a null date.

In the example below, \c s1, \c s2, \c + s3, \c s4 and \c s5 share data. + + \code + // all 5 strings share the same data + TQString s1 = "abcd"; + TQString s2 = s1; + TQString s3 = s2; + TQString s4 = s3; + TQString s5 = s2; + \endcode + + TQDeepCopy can be used several ways to ensure that an object + references unique, unshared data. In the example below, \c s1, \c + s2 and \c s5 share data, while neither \c s3 nor \c s4 share data. + \code + // s1, s2 and s5 share the same data, neither s3 nor s4 are shared + TQString s1 = "abcd"; + TQString s2 = s1; + TQDeepCopy<TQString> s3 = s2; // s3 is a deep copy of s2 + TQString s4 = s3; // s4 is a deep copy of s3 + TQString s5 = s2; + \endcode + + In the example below, \c s1, \c s2 and \c s5 share data, and \c s3 + and \c s4 share data. + \code + // s1, s2 and s5 share the same data, s3 and s4 share the same data + TQString s1 = "abcd"; + TQString s2 = s1; + TQString s3 = TQDeepCopy<TQString>( s2 ); // s3 is a deep copy of s2 + TQString s4 = s3; // s4 is a shallow copy of s3 + TQString s5 = s2; + \endcode + + TQDeepCopy can also provide safety in multithreaded applications + that use shared classes. In the example below, the variable \c + global_string is used safely since the data contained in \c + global_string is always a deep copy. This ensures that all threads + get a unique copy of the data, and that any assignments to \c + global_string will result in a deep copy. + + \code + TQDeepCopy<TQString> global_string; // global string data + TQMutex global_mutex; // mutex to protext global_string + + ... + + void setGlobalString( const TQString &str ) + { + global_mutex.lock(); + global_string = str; // global_string is a deep copy of str + global_mutex.unlock(); + } + + ... + + void MyThread::run() + { + global_mutex.lock(); + TQString str = global_string; // str is a deep copy of global_string + global_mutex.unlock(); + + // process the string data + ... + + // update global_string + setGlobalString( str ); + } + \endcode + + \warning It is the application developer's responsibility to + protect the object shared across multiple threads. + + The examples above use TQString, which is an implicitly shared + class.

Absolute paths begin with the directory separator "/" + (optionally preceded by a drive specification under Windows). If + you always use "/" as a directory separator, TQt will translate + your paths to conform to the underlying operating system. Relative + file names begin with a directory name or a file name and specify + a path relative to the current directory. + + The "current" path refers to the application's working directory. + A TQDir's own path is set and retrieved with setPath() and path(). + + An example of an absolute path is the string "/tmp/quartz", a + relative path might look like "src/fatlib". You can use the + function isRelative() to check if a TQDir is using a relative or an + absolute file path. Call convertToAbs() to convert a relative TQDir + to an absolute one. For a simplified path use cleanDirPath(). To + obtain a path which has no symbolic links or redundant ".." + elements use canonicalPath(). The path can be set with setPath(), + and changed with cd() and cdUp(). + + TQDir provides several static functions, for example, setCurrent() + to set the application's working directory and currentDirPath() to + retrieve the application's working directory. Access to some + common paths is provided with the static functions, current(), + home() and root() which return TQDir objects or currentDirPath(), + homeDirPath() and rootDirPath() which return the path as a string. + If you want to know about your application's path use + \l{TQApplication::applicationDirPath()}. + + The number of entries in a directory is returned by count(). + Obtain a string list of the names of all the files and directories + in a directory with entryList(). If you prefer a list of TQFileInfo + pointers use entryInfoList(). Both these functions can apply a + name filter, an attributes filter (e.g. read-only, files not + directories, etc.), and a sort order. The filters and sort may be + set with calls to setNameFilter(), setFilter() and setSorting(). + They may also be specified in the entryList() and + entryInfoList()'s arguments. + + Create a new directory with mkdir(), rename a directory with + rename() and remove an existing directory with rmdir(). Remove a + file with remove(). You can interrogate a directory with exists(), + isReadable() and isRoot(). + + To get a path with a filename use filePath(), and to get a + directory name use dirName(); neither of these functions checks + for the existence of the file or directory. + + The list of root directories is provided by drives(); on Unix + systems this returns a list containing one root directory, "/"; on + Windows the list will usually contain "C:/", and possibly "D:/", + etc. + + It is easiest to work with "/" separators in TQt code. If you need + to present a path to the user or need a path in a form suitable + for a function in the underlying operating system use + convertSeparators(). + + Examples: + + See if a directory exists. + \code + TQDir d( "example" ); // "./example" + if ( !d.exists() ) + qWarning( "Cannot find the example directory" ); + \endcode + + Traversing directories and reading a file. + \code + TQDir d = TQDir::root(); // "/" + if ( !d.cd("tmp") ) { // "/tmp" + qWarning( "Cannot find the \"/tmp\" directory" ); + } else { + TQFile f( d.filePath("ex1.txt") ); // "/tmp/ex1.txt" + if ( !f.open(IO_ReadWrite) ) + qWarning( "Cannot create the file %s", f.name() ); + } + \endcode + + A program that lists all the files in the current directory + (excluding symbolic links), sorted by size, smallest first: + \code + #include <stdio.h> + #include <qdir.h> + + int main( int argc, char **argv ) + { + TQDir d; + d.setFilter( TQDir::Files | TQDir::Hidden | TQDir::NoSymLinks ); + d.setSorting( TQDir::Size | TQDir::Reversed ); + + const TQFileInfoList *list = d.entryInfoList(); + TQFileInfoListIterator it( *list ); + TQFileInfo *fi; + + printf( " Bytes Filename\n" ); + while ( (fi = it.current()) != 0 ) { + printf( "%10li %s\n", fi->size(), fi->fileName().latin1() ); + ++it; + } + return 0; + } + \endcode + + \sa TQApplication::applicationDirPath() +*/ + +/*! + Constructs a TQDir pointing to the current directory ("."). + + \sa currentDirPath() +*/ + +TQDir::TQDir() +{ + dPath = TQString::fromLatin1("."); + init(); +} + +/*! + Constructs a TQDir with path \a path, that filters its entries by + name using \a nameFilter and by attributes using \a filterSpec.

A TQFile may be used by itself or more conveniently with a + TQDataStream or TQTextStream. + + The file name is usually passed in the constructor but can be + changed with setName(). You can check for a file's existence with + exists() and remove a file with remove(). + + The file is opened with open(), closed with close() and flushed + with flush(). Data is usually read and written using TQDataStream + or TQTextStream, but you can read with readBlock() and readLine() + and write with writeBlock(). TQFile also supports getch(), + ungetch() and putch(). + + The size of the file is returned by size(). You can get the + current file position or move to a new file position using the + at() functions. If you've reached the end of the file, atEnd() + returns TRUE. The file handle is returned by handle(). + + Here is a code fragment that uses TQTextStream to read a text file + line by line. It prints each line with a line number. + \code + TQStringList lines; + TQFile file( "file.txt" ); + if ( file.open( IO_ReadOnly ) ) { + TQTextStream stream( &file ); + TQString line; + int i = 1; + while ( !stream.atEnd() ) { + line = stream.readLine(); // line of text excluding '\n' + printf( "%3d: %s\n", i++, line.latin1() ); + lines += line; + } + file.close(); + } + \endcode + + Writing text is just as easy. The following example shows how to + write the data we read into the string list from the previous + example: + \code + TQFile file( "file.txt" ); + if ( file.open( IO_WriteOnly ) ) { + TQTextStream stream( &file ); + for ( TQStringList::Iterator it = lines.begin(); it != lines.end(); ++it ) + stream << *it << "\n"; + file.close(); + } + \endcode + + The TQFileInfo class holds detailed information about a file, such + as access permissions, file dates and file types. + + The TQDir class manages directories and lists of file names. + + TQt uses Unicode file names. If you want to do your own I/O on Unix + systems you may want to use encodeName() (and decodeName()) to + convert the file name into the local encoding. + + \important readAll() at() + + \sa TQDataStream, TQTextStream +*/ + +/*! + \fn Q_LONG TQFile::writeBlock( const TQByteArray& data ) + + \overload +*/ + + +/*! + Constructs a TQFile with no name. +*/ + +TQFile::TQFile() +: d(0) +{ + init(); +} + +/*! + Constructs a TQFile with a file name \a name. + + \sa setName() +*/ + +TQFile::TQFile( const TQString &name ) + : fn(name), d(0) +{ + init(); +} + + +/*! + Destroys a TQFile.

Absolute file paths begin with the directory + separator "/" (or with a drive specification on Windows). Relative + file names begin with a directory name or a file name and specify + a path relative to the current working directory. An example of an + absolute path is the string "/tmp/quartz". A relative path might + look like "src/fatlib". You can use the function isRelative() to + check whether a TQFileInfo is using a relative or an absolute file + path. You can call the function convertToAbs() to convert a + relative TQFileInfo's path to an absolute path. + + The file that the TQFileInfo works on is set in the constructor or + later with setFile(). Use exists() to see if the file exists and + size() to get its size. + + To speed up performance, TQFileInfo caches information about the + file. Because files can be changed by other users or programs, or + even by other parts of the same program, there is a function that + refreshes the file information: refresh(). If you want to switch + off a TQFileInfo's caching and force it to access the file system + every time you request information from it call setCaching(FALSE). + + The file's type is obtained with isFile(), isDir() and + isSymLink(). The readLink() function provides the name of the file + the symlink points to. + + Elements of the file's name can be extracted with dirPath() and + fileName(). The fileName()'s parts can be extracted with + baseName() and extension(). + + The file's dates are returned by created(), lastModified() and + lastRead(). Information about the file's access permissions is + obtained with isReadable(), isWritable() and isExecutable(). The + file's ownership is available from owner(), ownerId(), group() and + groupId(). You can examine a file's permissions and ownership in a + single statement using the permission() function. + + If you need to read and traverse directories, see the TQDir class. +*/ + +/*! + \enum TQFileInfo::PermissionSpec + + This enum is used by the permission() function to report the + permissions and ownership of a file.

The TQIODevice class is the abstract + superclass of all such devices; classes such as TQFile, TQBuffer and + TQSocket inherit TQIODevice and implement virtual functions such as + write() appropriately. + + Although applications sometimes use TQIODevice directly, it is + usually better to use TQTextStream and TQDataStream, which provide + stream operations on any TQIODevice subclass. TQTextStream provides + text-oriented stream functionality (for human-readable ASCII + files, for example), whereas TQDataStream deals with binary data in + a totally platform-independent manner. + + The public member functions in TQIODevice roughly fall into two + groups: the action functions and the state access functions. The + most important action functions are: + + \list + + \i open() opens a device for reading and/or writing, depending on + the mode argument. + + \i close() closes the device and tidies up (e.g. flushes buffered + data) + + \i readBlock() reads a block of data from the device. + + \i writeBlock() writes a block of data to the device. + + \i readLine() reads a line (of text, usually) from the device. + + \i flush() ensures that all buffered data are written to the real device. + + \endlist + + There are also some other, less used, action functions: + + \list + + \i getch() reads a single character. + + \i ungetch() forgets the last call to getch(), if possible. + + \i putch() writes a single character. + + \i size() returns the size of the device, if there is one. + + \i at() returns the current read/write pointer's position, if there + is one for this device, or it moves the pointer if given an offset. + + \i atEnd() indicates whether there is more to read, if this is + meaningful for this device. + + \i reset() moves the read/write pointer to the start of the + device, if that is possible for this device. + + \endlist + + The state access are all "get" functions. The TQIODevice subclass + calls setState() to update the state, and simple access functions + tell the user of the device what the device's state is. Here are + the settings, and their associated access functions: + + \list + + \i Access type. Some devices are direct access (it is possible + to read/write anywhere), whereas others are sequential. TQIODevice + provides the access functions (isDirectAccess(), + isSequentialAccess(), and isCombinedAccess()) to tell users what a + given I/O device supports. + + \i Buffering. Some devices are accessed in raw mode, whereas + others are buffered. Buffering usually provides greater + efficiency, particularly for small read/write operations. + isBuffered() tells the user whether a given device is buffered. + (This can often be set by the application in the call to open().) + + \i Synchronicity. Synchronous devices work immediately (for + example, files). When you read from a file, the file delivers its + data straight away. Other kinds of device, such as a socket + connected to a HTTP server, may not deliver the data until seconds + after you ask to read it. isSynchronous() and isAsynchronous() + tell the user how this device operates. + + \i CR/LF translation. For simplicity, applications often like to + see just a single CR/LF style, and TQIODevice subclasses can + provide this. isTranslated() returns TRUE if this object + translates CR/LF to just LF. (This can often be set by the + application in the call to open().) + + \i Permissions. Some files cannot be written. For example, + isReadable(), isWritable() and isReadWrite() tell the application + whether it can read from and write to a given device. (This can + often be set by the application in the call to open().) + + \i Finally, isOpen() returns TRUE if the device is open, i.e. + after an open() call. + + \endlist + + TQIODevice provides numerous pure virtual functions that you need + to implement when subclassing it. Here is a skeleton subclass with + all the members you are sure to need and some that you will + probably need: + + \code + class MyDevice : public TQIODevice + { + public: + MyDevice(); + ~MyDevice(); + + bool open( int mode ); + void close(); + void flush(); + + uint size() const; + int at() const; // non-pure virtual + bool at( int ); // non-pure virtual + bool atEnd() const; // non-pure virtual + + int readBlock( char *data, uint maxlen ); + int writeBlock( const char *data, uint len ); + int readLine( char *data, uint maxlen ); + + int getch(); + int putch( int ); + int ungetch( int ); + }; + \endcode + + The three non-pure virtual functions need not be reimplemented for + sequential devices. + + \sa TQDataStream, TQTextStream +*/ + +/*! + \enum TQIODevice::Offset + + The offset within the device. +*/ + + +/*! + Constructs an I/O device. +*/ + +TQIODevice::TQIODevice() +{ + ioMode = 0; // initial mode + ioSt = IO_Ok; + ioIndex = 0; +} + +/*! + Destroys the I/O device. +*/ + +TQIODevice::~TQIODevice() +{ +} + + +/*! + \fn int TQIODevice::flags() const + + Returns the current I/O device flags setting. + + Flags consists of mode flags and state flags. + + \sa mode(), state() +*/ + +/*! + \fn int TQIODevice::mode() const + + Returns bits OR'ed together that specify the current operation + mode. + + These are the flags that were given to the open() function. + + The flags are \c IO_ReadOnly, \c IO_WriteOnly, \c IO_ReadWrite, + \c IO_Append, \c IO_Truncate and \c IO_Translate. +*/ + +/*! + \fn int TQIODevice::state() const + + Returns bits OR'ed together that specify the current state. + + The flags are: \c IO_Open. + + Subclasses may define additional flags. +*/ + +/*! + \fn bool TQIODevice::isDirectAccess() const + + Returns TRUE if the I/O device is a direct access device; + otherwise returns FALSE, i.e. if the device is a sequential access + device. + + \sa isSequentialAccess() +*/ + +/*! + \fn bool TQIODevice::isSequentialAccess() const + + Returns TRUE if the device is a sequential access device; + otherwise returns FALSE, i.e. if the device is a direct access + device. + + Operations involving size() and at(int) are not valid on + sequential devices. + + \sa isDirectAccess() +*/ + +/*! + \fn bool TQIODevice::isCombinedAccess() const + + Returns TRUE if the I/O device is a combined access (both direct + and sequential) device; otherwise returns FALSE. + + This access method is currently not in use. +*/ + +/*! + \fn bool TQIODevice::isBuffered() const + + Returns TRUE if the I/O device is a buffered device; otherwise + returns FALSE, i.e. the device is a raw device. + + \sa isRaw() +*/ + +/*! + \fn bool TQIODevice::isRaw() const + + Returns TRUE if the device is a raw device; otherwise returns + FALSE, i.e. if the device is a buffered device. + + \sa isBuffered() +*/ + +/*! + \fn bool TQIODevice::isSynchronous() const + + Returns TRUE if the I/O device is a synchronous device; otherwise + returns FALSE, i.e. the device is an asynchronous device. + + \sa isAsynchronous() +*/ + +/*! + \fn bool TQIODevice::isAsynchronous() const + + Returns TRUE if the device is an asynchronous device; otherwise + returns FALSE, i.e. if the device is a synchronous device. + + This mode is currently not in use. + + \sa isSynchronous() +*/ + +/*! + \fn bool TQIODevice::isTranslated() const + + Returns TRUE if the I/O device translates carriage-return and + linefeed characters; otherwise returns FALSE. + + A TQFile is translated if it is opened with the \c IO_Translate + mode flag. +*/ + +/*! + \fn bool TQIODevice::isReadable() const + + Returns TRUE if the I/O device was opened using \c IO_ReadOnly or + \c IO_ReadWrite mode; otherwise returns FALSE. + + \sa isWritable(), isReadWrite() +*/ + +/*! + \fn bool TQIODevice::isWritable() const + + Returns TRUE if the I/O device was opened using \c IO_WriteOnly or + \c IO_ReadWrite mode; otherwise returns FALSE. + + \sa isReadable(), isReadWrite() +*/ + +/*! + \fn bool TQIODevice::isReadWrite() const + + Returns TRUE if the I/O device was opened using \c IO_ReadWrite + mode; otherwise returns FALSE. + + \sa isReadable(), isWritable() +*/ + +/*! + \fn bool TQIODevice::isInactive() const + + Returns TRUE if the I/O device state is 0, i.e. the device is not + open; otherwise returns FALSE. + + \sa isOpen() +*/ + +/*! + \fn bool TQIODevice::isOpen() const + + Returns TRUE if the I/O device has been opened; otherwise returns + FALSE. + + \sa isInactive() +*/ + + +/*! + \fn int TQIODevice::status() const + + Returns the I/O device status. + + The I/O device status returns an error code.

We remove common factors of powers of 2 from relevant + * quantities. + * 5. When converting floating-point integers less than 1e16, + * we use floating-point arithmetic rather than resorting + * to multiple-precision integers. + * 6. When asked to produce fewer than 15 digits, we first try + * to get by with floating-point arithmetic; we resort to + * multiple-precision integer arithmetic only if we cannot + * guarantee that the floating-point calculation has given + * the correctly rounded result.

Locking and unlocking a TQMutex in complex functions and + statements or in exception handling code is error prone and + difficult to debug. TQMutexLocker should be used in such situations + to ensure that the state of the mutex is well defined and always + locked and unlocked properly. + + TQMutexLocker should be created within a function where a TQMutex + needs to be locked. The mutex is locked when TQMutexLocker is + created, and unlocked when TQMutexLocker is destroyed. + + For example, this complex function locks a TQMutex upon entering + the function and unlocks the mutex at all the exit points: + + \code + int complexFunction( int flag ) + { + mutex.lock(); + + int return_value = 0; + + switch ( flag ) { + case 0: + case 1: + { + mutex.unlock(); + return moreComplexFunction( flag ); + } + + case 2: + { + int status = anotherFunction(); + if ( status < 0 ) { + mutex.unlock(); + return -2; + } + return_value = status + flag; + break; + } + + default: + { + if ( flag > 10 ) { + mutex.unlock(); + return -1; + } + break; + } + } + + mutex.unlock(); + return return_value; + } + \endcode + + This example function will get more complicated as it is + developed, which increases the likelihood that errors will occur. + + Using TQMutexLocker greatly simplifies the code, and makes it more + readable: + + \code + int complexFunction( int flag ) + { + TQMutexLocker locker( &mutex ); + + int return_value = 0; + + switch ( flag ) { + case 0: + case 1: + { + return moreComplexFunction( flag ); + } + + case 2: + { + int status = anotherFunction(); + if ( status < 0 ) + return -2; + return_value = status + flag; + break; + } + + default: + { + if ( flag > 10 ) + return -1; + break; + } + } + + return return_value; + } + \endcode + + Now, the mutex will always be unlocked when the TQMutexLocker + object is destroyed (when the function returns since \c locker is + an auto variable). Note that the mutex will be unlocked after + the call to moreComplexFunction() in this example, avoiding + possible bugs caused by unlocking the mutex too early, as in + the first example. + + The same principle applies to code that throws and catches + exceptions. An exception that is not caught in the function that + has locked the mutex has no way of unlocking the mutex before the + exception is passed up the stack to the calling function. + + TQMutexLocker also provides a mutex() member function that returns + the mutex on which the TQMutexLocker is operating. This is useful + for code that needs access to the mutex, such as + TQWaitCondition::wait(). For example: + + \code + class SignalWaiter + { + private: + TQMutexLocker locker; + + public: + SignalWaiter( TQMutex *mutex ) + : locker( mutex ) + { + } + + void waitForSignal() + { + ... + ... + ... + + while ( ! signalled ) + waitcondition.wait( locker.mutex() ); + + ... + ... + ... + } + }; + \endcode + + \sa TQMutex, TQWaitCondition +*/ + +/*! + \fn TQMutexLocker::TQMutexLocker( TQMutex *mutex ) + + Constructs a TQMutexLocker and locks \a mutex.

This is useful in many contexts, for example: + + \table + \row \i Validation + \i A regexp can be used to check whether a piece of text + meets some criteria, e.g. is an integer or contains no + whitespace. + \row \i Searching + \i Regexps provide a much more powerful means of searching + text than simple string matching does.

TQRegExp is modeled on Perl's regexp + language, and also fully supports Unicode.

A good text on regexps is \e + {Mastering Regular Expressions: Powerful Techniques for Perl and + Other Tools} by Jeffrey E. Friedl, ISBN 1565922573. + + Experienced regexp users may prefer to skip the introduction and + go directly to the relevant information. + + In case of multi-threaded programming, note that TQRegExp depends on + TQThreadStorage internally. For that reason, TQRegExp should only be + used with threads started with TQThread, i.e. not with threads + started with platform-specific APIs. + + \tableofcontents + + \section1 Introduction + + Regexps are built up from expressions, quantifiers, and assertions. + The simplest form of expression is simply a character, e.g. + <b>x</b> or <b>5</b>. An expression can also be a set of + characters. For example, <b>[ABCD]</b>, will match an <b>A</b> or + a <b>B</b> or a <b>C</b> or a <b>D</b>. As a shorthand we could + write this as <b>[A-D]</b>. If we want to match any of the + captital letters in the English alphabet we can write + <b>[A-Z]</b>. A quantifier tells the regexp engine how many + occurrences of the expression we want, e.g. <b>x{1,1}</b> means + match an <b>x</b> which occurs at least once and at most once. + We'll look at assertions and more complex expressions later. + + Note that in general regexps cannot be used to check for balanced + brackets or tags. For example if you want to match an opening html + \c <b> and its closing \c </b> you can only use a regexp if you + know that these tags are not nested; the html fragment, \c{<b>bold + <b>bolder</b></b>} will not match as expected. If you know the + maximum level of nesting it is possible to create a regexp that + will match correctly, but for an unknown level of nesting, regexps + will fail. + + We'll start by writing a regexp to match integers in the range 0 + to 99. We will retquire at least one digit so we will start with + <b>[0-9]{1,1}</b> which means match a digit exactly once. This + regexp alone will match integers in the range 0 to 9. To match one + or two digits we can increase the maximum number of occurrences so + the regexp becomes <b>[0-9]{1,2}</b> meaning match a digit at + least once and at most twice. However, this regexp as it stands + will not match correctly. This regexp will match one or two digits + \e within a string. To ensure that we match against the whole + string we must use the anchor assertions. We need <b>^</b> (caret) + which when it is the first character in the regexp means that the + regexp must match from the beginning of the string. And we also + need <b>$</b> (dollar) which when it is the last character in the + regexp means that the regexp must match until the end of the + string. So now our regexp is <b>^[0-9]{1,2}$</b>. Note that + assertions, such as <b>^</b> and <b>$</b>, do not match any + characters. + + If you've seen regexps elsewhere they may have looked different from + the ones above. This is because some sets of characters and some + quantifiers are so common that they have special symbols to + represent them. <b>[0-9]</b> can be replaced with the symbol + <b>\d</b>. The quantifier to match exactly one occurrence, + <b>{1,1}</b>, can be replaced with the expression itself. This means + that <b>x{1,1}</b> is exactly the same as <b>x</b> alone. So our 0 + to 99 matcher could be written <b>^\d{1,2}$</b>. Another way of + writing it would be <b>^\d\d{0,1}$</b>, i.e. from the start of the + string match a digit followed by zero or one digits. In practice + most people would write it <b>^\d\d?$</b>. The <b>?</b> is a + shorthand for the quantifier <b>{0,1}</b>, i.e. a minimum of no + occurrences a maximum of one occurrence. This is used to make an + expression optional. The regexp <b>^\d\d?$</b> means "from the + beginning of the string match one digit followed by zero or one + digits and then the end of the string". + + Our second example is matching the words 'mail', 'letter' or + 'correspondence' but without matching 'email', 'mailman', + 'mailer', 'letterbox' etc. We'll start by just matching 'mail'. In + full the regexp is, <b>m{1,1}a{1,1}i{1,1}l{1,1}</b>, but since + each expression itself is automatically quantified by <b>{1,1}</b> + we can simply write this as <b>mail</b>; an 'm' followed by an 'a' + followed by an 'i' followed by an 'l'. The symbol '|' (bar) is + used for \e alternation, so our regexp now becomes + <b>mail|letter|correspondence</b> which means match 'mail' \e or + 'letter' \e or 'correspondence'. Whilst this regexp will find the + words we want it will also find words we don't want such as + 'email'. We will start by putting our regexp in parentheses, + <b>(mail|letter|correspondence)</b>. Parentheses have two effects, + firstly they group expressions together and secondly they identify + parts of the regexp that we wish to \link #capturing-text capture + \endlink. Our regexp still matches any of the three words but now + they are grouped together as a unit. This is useful for building + up more complex regexps. It is also useful because it allows us to + examine which of the words actually matched. We need to use + another assertion, this time <b>\b</b> "word boundary": + <b>\b(mail|letter|correspondence)\b</b>. This regexp means "match + a word boundary followed by the expression in parentheses followed + by another word boundary". The <b>\b</b> assertion matches at a \e + position in the regexp not a \e character in the regexp. A word + boundary is any non-word character such as a space a newline or + the beginning or end of the string. + + For our third example we want to replace ampersands with the HTML + entity '\&'. The regexp to match is simple: <b>\&</b>, i.e. + match one ampersand. Unfortunately this will mess up our text if + some of the ampersands have already been turned into HTML + entities. So what we really want to say is replace an ampersand + providing it is not followed by 'amp;'. For this we need the + negative lookahead assertion and our regexp becomes: + <b>\&(?!amp;)</b>. The negative lookahead assertion is introduced + with '(?!' and finishes at the ')'. It means that the text it + contains, 'amp;' in our example, must \e not follow the expression + that preceeds it. + + Regexps provide a rich language that can be used in a variety of + ways. For example suppose we want to count all the occurrences of + 'Eric' and 'Eirik' in a string. Two valid regexps to match these + are <b>\\b(Eric|Eirik)\\b</b> and <b>\\bEi?ri[ck]\\b</b>. We need + the word boundary '\b' so we don't get 'Ericsson' etc. The second + regexp actually matches more than we want, 'Eric', 'Erik', 'Eiric' + and 'Eirik'. + + We will implement some the examples above in the + \link #code-examples code examples \endlink section. + + \target characters-and-abbreviations-for-sets-of-characters + \section1 Characters and Abbreviations for Sets of Characters + + \table + \header \i Element \i Meaning + \row \i <b>c</b> + \i Any character represents itself unless it has a special + regexp meaning. Thus <b>c</b> matches the character \e c. + \row \i <b>\\c</b> + \i A character that follows a backslash matches the character + itself except where mentioned below. For example if you + wished to match a literal caret at the beginning of a string + you would write <b>\^</b>. + \row \i <b>\\a</b> + \i This matches the ASCII bell character (BEL, 0x07). + \row \i <b>\\f</b> + \i This matches the ASCII form feed character (FF, 0x0C). + \row \i <b>\\n</b> + \i This matches the ASCII line feed character (LF, 0x0A, Unix newline). + \row \i <b>\\r</b> + \i This matches the ASCII carriage return character (CR, 0x0D). + \row \i <b>\\t</b> + \i This matches the ASCII horizontal tab character (HT, 0x09). + \row \i <b>\\v</b> + \i This matches the ASCII vertical tab character (VT, 0x0B). + \row \i <b>\\xhhhh</b> + \i This matches the Unicode character corresponding to the + hexadecimal number hhhh (between 0x0000 and 0xFFFF). \0ooo + (i.e., \zero ooo) matches the ASCII/Latin-1 character + corresponding to the octal number ooo (between 0 and 0377). + \row \i <b>. (dot)</b> + \i This matches any character (including newline). + \row \i <b>\\d</b> + \i This matches a digit (TQChar::isDigit()). + \row \i <b>\\D</b> + \i This matches a non-digit. + \row \i <b>\\s</b> + \i This matches a whitespace (TQChar::isSpace()). + \row \i <b>\\S</b> + \i This matches a non-whitespace. + \row \i <b>\\w</b> + \i This matches a word character (TQChar::isLetterOrNumber() or '_'). + \row \i <b>\\W</b> + \i This matches a non-word character. + \row \i <b>\\n</b> + \i The n-th \link #capturing-text backreference \endlink, + e.g. \1, \2, etc. + \endtable + + \e {Note that the C++ compiler transforms backslashes in strings + so to include a <b>\\</b> in a regexp you will need to enter it + twice, i.e. <b>\\\\</b>.} + + \target sets-of-characters + \section1 Sets of Characters + + Square brackets are used to match any character in the set of + characters contained within the square brackets. All the character + set abbreviations described above can be used within square + brackets. Apart from the character set abbreviations and the + following two exceptions no characters have special meanings in + square brackets. + + \table + \row \i <b>^</b> + \i The caret negates the character set if it occurs as the + first character, i.e. immediately after the opening square + bracket. For example, <b>[abc]</b> matches 'a' or 'b' or 'c', + but <b>[^abc]</b> matches anything \e except 'a' or 'b' or + 'c'. + \row \i <b>-</b> + \i The dash is used to indicate a range of characters, for + example <b>[W-Z]</b> matches 'W' or 'X' or 'Y' or 'Z'. + \endtable + + Using the predefined character set abbreviations is more portable + than using character ranges across platforms and languages. For + example, <b>[0-9]</b> matches a digit in Western alphabets but + <b>\d</b> matches a digit in \e any alphabet. + + Note that in most regexp literature sets of characters are called + "character classes". + + \target quantifiers + \section1 Quantifiers + + By default an expression is automatically quantified by + <b>{1,1}</b>, i.e. it should occur exactly once. In the following + list <b>\e {E}</b> stands for any expression. An expression is a + character or an abbreviation for a set of characters or a set of + characters in square brackets or any parenthesised expression. + + \table + \row \i <b>\e {E}?</b> + \i Matches zero or one occurrence of \e E. This quantifier + means "the previous expression is optional" since it will + match whether or not the expression occurs in the string. It + is the same as <b>\e {E}{0,1}</b>. For example <b>dents?</b> + will match 'dent' and 'dents'. + + \row \i <b>\e {E}+</b> + \i Matches one or more occurrences of \e E. This is the same + as <b>\e {E}{1,MAXINT}</b>. For example, <b>0+</b> will match + '0', '00', '000', etc. + + \row \i <b>\e {E}*</b> + \i Matches zero or more occurrences of \e E. This is the same + as <b>\e {E}{0,MAXINT}</b>. The <b>*</b> quantifier is often + used by a mistake. Since it matches \e zero or more + occurrences it will match no occurrences at all. For example + if we want to match strings that end in whitespace and use + the regexp <b>\s*$</b> we would get a match on every string. + This is because we have said find zero or more whitespace + followed by the end of string, so even strings that don't end + in whitespace will match. The regexp we want in this case is + <b>\s+$</b> to match strings that have at least one + whitespace at the end. + + \row \i <b>\e {E}{n}</b> + \i Matches exactly \e n occurrences of the expression. This + is the same as repeating the expression \e n times. For + example, <b>x{5}</b> is the same as <b>xxxxx</b>. It is also + the same as <b>\e {E}{n,n}</b>, e.g. <b>x{5,5}</b>. + + \row \i <b>\e {E}{n,}</b> + \i Matches at least \e n occurrences of the expression. This + is the same as <b>\e {E}{n,MAXINT}</b>. + + \row \i <b>\e {E}{,m}</b> + \i Matches at most \e m occurrences of the expression. This + is the same as <b>\e {E}{0,m}</b>. + + \row \i <b>\e {E}{n,m}</b> + \i Matches at least \e n occurrences of the expression and at + most \e m occurrences of the expression. + \endtable + + (MAXINT is implementation dependent but will not be smaller than + 1024.) + + If we wish to apply a quantifier to more than just the preceding + character we can use parentheses to group characters together in + an expression. For example, <b>tag+</b> matches a 't' followed by + an 'a' followed by at least one 'g', whereas <b>(tag)+</b> matches + at least one occurrence of 'tag'. + + Note that quantifiers are "greedy". They will match as much text + as they can. For example, <b>0+</b> will match as many zeros as it + can from the first zero it finds, e.g. '2.<u>000</u>5'. + Quantifiers can be made non-greedy, see setMinimal(). + + \target capturing-text + \section1 Capturing Text + + Parentheses allow us to group elements together so that we can + quantify and capture them. For example if we have the expression + <b>mail|letter|correspondence</b> that matches a string we know + that \e one of the words matched but not which one. Using + parentheses allows us to "capture" whatever is matched within + their bounds, so if we used <b>(mail|letter|correspondence)</b> + and matched this regexp against the string "I sent you some email" + we can use the cap() or capturedTexts() functions to extract the + matched characters, in this case 'mail'. + + We can use captured text within the regexp itself. To refer to the + captured text we use \e backreferences which are indexed from 1, + the same as for cap(). For example we could search for duplicate + words in a string using <b>\b(\w+)\W+\1\b</b> which means match a + word boundary followed by one or more word characters followed by + one or more non-word characters followed by the same text as the + first parenthesised expression followed by a word boundary. + + If we want to use parentheses purely for grouping and not for + capturing we can use the non-capturing syntax, e.g. + <b>(?:green|blue)</b>. Non-capturing parentheses begin '(?:' and + end ')'. In this example we match either 'green' or 'blue' but we + do not capture the match so we only know whether or not we matched + but not which color we actually found. Using non-capturing + parentheses is more efficient than using capturing parentheses + since the regexp engine has to do less book-keeping. + + Both capturing and non-capturing parentheses may be nested. + + \target assertions + \section1 Assertions + + Assertions make some statement about the text at the point where + they occur in the regexp but they do not match any characters. In + the following list <b>\e {E}</b> stands for any expression. + + \table + \row \i <b>^</b> + \i The caret signifies the beginning of the string. If you + wish to match a literal \c{^} you must escape it by + writing <b>\^</b>. For example, <b>^#include</b> will only + match strings which \e begin with the characters '#include'. + (When the caret is the first character of a character set it + has a special meaning, see \link #sets-of-characters Sets of + Characters \endlink.) + + \row \i <b>$</b> + \i The dollar signifies the end of the string. For example + <b>\d\s*$</b> will match strings which end with a digit + optionally followed by whitespace. If you wish to match a + literal \c{$} you must escape it by writing + <b>\$</b>. + + \row \i <b>\\b</b> + \i A word boundary. For example the regexp + <b>\\bOK\\b</b> means match immediately after a word + boundary (e.g. start of string or whitespace) the letter 'O' + then the letter 'K' immediately before another word boundary + (e.g. end of string or whitespace). But note that the + assertion does not actually match any whitespace so if we + write <b>(\\bOK\\b)</b> and we have a match it will only + contain 'OK' even if the string is "Its <u>OK</u> now". + + \row \i <b>\\B</b> + \i A non-word boundary. This assertion is true wherever + <b>\\b</b> is false. For example if we searched for + <b>\\Bon\\B</b> in "Left on" the match would fail (space + and end of string aren't non-word boundaries), but it would + match in "t<u>on</u>ne". + + \row \i <b>(?=\e E)</b> + \i Positive lookahead. This assertion is true if the + expression matches at this point in the regexp. For example, + <b>const(?=\\s+char)</b> matches 'const' whenever it is + followed by 'char', as in 'static <u>const</u> char *'. + (Compare with <b>const\\s+char</b>, which matches 'static + <u>const char</u> *'.) + + \row \i <b>(?!\e E)</b> + \i Negative lookahead. This assertion is true if the + expression does not match at this point in the regexp. For + example, <b>const(?!\\s+char)</b> matches 'const' \e except + when it is followed by 'char'. + \endtable + + \target wildcard-matching + \section1 Wildcard Matching (globbing) + + Most command shells such as \e bash or \e cmd.exe support "file + globbing", the ability to identify a group of files by using + wildcards. The setWildcard() function is used to switch between + regexp and wildcard mode. Wildcard matching is much simpler than + full regexps and has only four features: + + \table + \row \i <b>c</b> + \i Any character represents itself apart from those mentioned + below. Thus <b>c</b> matches the character \e c. + \row \i <b>?</b> + \i This matches any single character. It is the same as + <b>.</b> in full regexps. + \row \i <b>*</b> + \i This matches zero or more of any characters. It is the + same as <b>.*</b> in full regexps. + \row \i <b>[...]</b> + \i Sets of characters can be represented in square brackets, + similar to full regexps. Within the character class, like + outside, backslash has no special meaning. + \endtable + + For example if we are in wildcard mode and have strings which + contain filenames we could identify HTML files with <b>*.html</b>. + This will match zero or more characters followed by a dot followed + by 'h', 't', 'm' and 'l'. + + \target perl-users + \section1 Notes for Perl Users + + Most of the character class abbreviations supported by Perl are + supported by TQRegExp, see \link + #characters-and-abbreviations-for-sets-of-characters characters + and abbreviations for sets of characters \endlink. + + In TQRegExp, apart from within character classes, \c{^} always + signifies the start of the string, so carets must always be + escaped unless used for that purpose. In Perl the meaning of caret + varies automagically depending on where it occurs so escaping it + is rarely necessary. The same applies to \c{$} which in + TQRegExp always signifies the end of the string. + + TQRegExp's quantifiers are the same as Perl's greedy quantifiers. + Non-greedy matching cannot be applied to individual quantifiers, + but can be applied to all the quantifiers in the pattern. For + example, to match the Perl regexp <b>ro+?m</b> retquires: + \code + TQRegExp rx( "ro+m" ); + rx.setMinimal( TRUE ); + \endcode + + The equivalent of Perl's \c{/i} option is + setCaseSensitive(FALSE). + + Perl's \c{/g} option can be emulated using a \link + #cap_in_a_loop loop \endlink. + + In TQRegExp <b>.</b> matches any character, therefore all TQRegExp + regexps have the equivalent of Perl's \c{/s} option. TQRegExp + does not have an equivalent to Perl's \c{/m} option, but this + can be emulated in various ways for example by splitting the input + into lines or by looping with a regexp that searches for newlines. + + Because TQRegExp is string oriented there are no \A, \Z or \z + assertions. The \G assertion is not supported but can be emulated + in a loop. + + Perl's $& is cap(0) or capturedTexts()[0]. There are no TQRegExp + equivalents for $`, $' or $+. Perl's capturing variables, $1, $2, + ... correspond to cap(1) or capturedTexts()[1], cap(2) or + capturedTexts()[2], etc. + + To substitute a pattern use TQString::replace(). + + Perl's extended \c{/x} syntax is not supported, nor are + directives, e.g. (?i), or regexp comments, e.g. (?#comment). On + the other hand, C++'s rules for literal strings can be used to + achieve the same: + \code + TQRegExp mark( "\\b" // word boundary + "[Mm]ark" // the word we want to match + ); + \endcode + + Both zero-width positive and zero-width negative lookahead + assertions (?=pattern) and (?!pattern) are supported with the same + syntax as Perl. Perl's lookbehind assertions, "independent" + subexpressions and conditional expressions are not supported. + + Non-capturing parentheses are also supported, with the same + (?:pattern) syntax. + + See TQStringList::split() and TQStringList::join() for equivalents + to Perl's split and join functions. + + Note: because C++ transforms \\'s they must be written \e twice in + code, e.g. <b>\\b</b> must be written <b>\\\\b</b>. + + \target code-examples + \section1 Code Examples + + \code + TQRegExp rx( "^\\d\\d?$" ); // match integers 0 to 99 + rx.search( "123" ); // returns -1 (no match) + rx.search( "-6" ); // returns -1 (no match) + rx.search( "6" ); // returns 0 (matched as position 0) + \endcode + + The third string matches '<u>6</u>'. This is a simple validation + regexp for integers in the range 0 to 99. + + \code + TQRegExp rx( "^\\S+$" ); // match strings without whitespace + rx.search( "Hello world" ); // returns -1 (no match) + rx.search( "This_is-OK" ); // returns 0 (matched at position 0) + \endcode + + The second string matches '<u>This_is-OK</u>'. We've used the + character set abbreviation '\S' (non-whitespace) and the anchors + to match strings which contain no whitespace. + + In the following example we match strings containing 'mail' or + 'letter' or 'correspondence' but only match whole words i.e. not + 'email' + + \code + TQRegExp rx( "\\b(mail|letter|correspondence)\\b" ); + rx.search( "I sent you an email" ); // returns -1 (no match) + rx.search( "Please write the letter" ); // returns 17 + \endcode + + The second string matches "Please write the <u>letter</u>". The + word 'letter' is also captured (because of the parentheses). We + can see what text we've captured like this: + + \code + TQString captured = rx.cap( 1 ); // captured == "letter" + \endcode + + This will capture the text from the first set of capturing + parentheses (counting capturing left parentheses from left to + right). The parentheses are counted from 1 since cap( 0 ) is the + whole matched regexp (equivalent to '&' in most regexp engines). + + \code + TQRegExp rx( "&(?!amp;)" ); // match ampersands but not & + TQString line1 = "This & that"; + line1.replace( rx, "&" ); + // line1 == "This & that" + TQString line2 = "His & hers & theirs"; + line2.replace( rx, "&" ); + // line2 == "His & hers & theirs" + \endcode + + Here we've passed the TQRegExp to TQString's replace() function to + replace the matched text with new text. + + \code + TQString str = "One Eric another Eirik, and an Ericsson." + " How many Eiriks, Eric?"; + TQRegExp rx( "\\b(Eric|Eirik)\\b" ); // match Eric or Eirik + int pos = 0; // where we are in the string + int count = 0; // how many Eric and Eirik's we've counted + while ( pos >= 0 ) { + pos = rx.search( str, pos ); + if ( pos >= 0 ) { + pos++; // move along in str + count++; // count our Eric or Eirik + } + } + \endcode + + We've used the search() function to repeatedly match the regexp in + the string. Note that instead of moving forward by one character + at a time \c pos++ we could have written \c {pos += + rx.matchedLength()} to skip over the already matched string. The + count will equal 3, matching 'One <u>Eric</u> another + <u>Eirik</u>, and an Ericsson. How many Eiriks, <u>Eric</u>?'; it + doesn't match 'Ericsson' or 'Eiriks' because they are not bounded + by non-word boundaries. + + One common use of regexps is to split lines of delimited data into + their component fields. + + \code + str = "Trolltech AS\twww.trolltech.com\tNorway"; + TQString company, web, country; + rx.setPattern( "^([^\t]+)\t([^\t]+)\t([^\t]+)$" ); + if ( rx.search( str ) != -1 ) { + company = rx.cap( 1 ); + web = rx.cap( 2 ); + country = rx.cap( 3 ); + } + \endcode + + In this example our input lines have the format company name, web + address and country. Unfortunately the regexp is rather long and + not very versatile -- the code will break if we add any more + fields. A simpler and better solution is to look for the + separator, '\t' in this case, and take the surrounding text. The + TQStringList split() function can take a separator string or regexp + as an argument and split a string accordingly. + + \code + TQStringList field = TQStringList::split( "\t", str ); + \endcode + + Here field[0] is the company, field[1] the web address and so on. + + To imitate the matching of a shell we can use wildcard mode. + + \code + TQRegExp rx( "*.html" ); // invalid regexp: * doesn't quantify anything + rx.setWildcard( TRUE ); // now it's a valid wildcard regexp + rx.exactMatch( "index.html" ); // returns TRUE + rx.exactMatch( "default.htm" ); // returns FALSE + rx.exactMatch( "readme.txt" ); // returns FALSE + \endcode + + Wildcard matching can be convenient because of its simplicity, but + any wildcard regexp can be defined using full regexps, e.g. + <b>.*\.html$</b>. Notice that we can't match both \c .html and \c + .htm files with a wildcard unless we use <b>*.htm*</b> which will + also match 'test.html.bak'. A full regexp gives us the precision + we need, <b>.*\\.html?$</b>. + + TQRegExp can match case insensitively using setCaseSensitive(), and + can use non-greedy matching, see setMinimal(). By default TQRegExp + uses full regexps but this can be changed with setWildcard(). + Searching can be forward with search() or backward with + searchRev().

A semaphore differs from a mutex, in + that a semaphore can be accessed by more than one thread at a + time. + + For example, suppose we have an application that stores data in a + large tree structure. The application creates 10 threads + (commonly called a thread pool) to perform searches on the tree. + When the application searches the tree for some piece of data, it + uses one thread per base node to do the searching. A semaphore + could be used to make sure that two threads don't try to search + the same branch of the tree at the same time. + + A non-computing example of a semaphore would be dining at a + restuarant. A semaphore is initialized to have a maximum count + equal to the number of chairs in the restuarant. As people + arrive, they want a seat. As seats are filled, the semaphore is + accessed, once per person. As people leave, the access is + released, allowing more people to enter. If a party of 10 people + want to be seated, but there are only 9 seats, those 10 people + will wait, but a party of 4 people would be seated (taking the + available seats to 5, making the party of 10 people wait longer). + + When a semaphore is created it is given a number which is the + maximum number of concurrent accesses it will permit. Accesses to + the sempahore are gained using operator++() or operator+=(), and + released with operator--() or operator-=().

On Windows + systems, TQSettings uses the system registry. On Mac OS X, TQSettings uses + the Carbon preferences API. + + Each setting comprises an identifying key and the data associated with + the key. A key is a unicode string which consists of \e two or more + subkeys. A subkey is a slash, '/', followed by one or more unicode + characters (excluding slashes, newlines, carriage returns and equals, + '=', signs). The associated data, called the entry or value, may be a + boolean, an integer, a double, a string or a list of strings. Entry + strings may contain any unicode characters. + + If you want to save and restore the entire desktop's settings, i.e. + which applications are running, use TQSettings to save the settings + for each individual application and TQSessionManager to save the + desktop's session. + + Example settings: + \code + /MyCompany/MyApplication/background color + /MyCompany/MyApplication/foreground color + /MyCompany/MyApplication/geometry/x + /MyCompany/MyApplication/geometry/y + /MyCompany/MyApplication/geometry/width + /MyCompany/MyApplication/geometry/height + /MyCompany/MyApplication/recent files/1 + /MyCompany/MyApplication/recent files/2 + /MyCompany/MyApplication/recent files/3 + \endcode + Each line above is a complete key, made up of subkeys. + + A typical usage pattern for reading settings at application + startup: + \code + TQSettings settings; + settings.setPath( "MyCompany.com", "MyApplication" ); + + TQString bgColor = settings.readEntry( "/colors/background", "white" ); + int width = settings.readNumEntry( "/geometry/width", 640 ); + // ... + \endcode + + A typical usage pattern for saving settings at application exit or + 'save preferences': + \code + TQSettings settings; + settings.setPath( "MyCompany.com", "MyApplication" ); + + settings.writeEntry( "/colors/background", bgColor ); + settings.writeEntry( "/geometry/width", width ); + // ... + \endcode + + A key prefix can be prepended to all keys using beginGroup(). The + application of the prefix is stopped using endGroup(). For + example: + \code + TQSettings settings; + + settings.beginGroup( "/MainWindow" ); + settings.beginGroup( "/Geometry" ); + int x = settings.readEntry( "/x" ); + // ... + settings.endGroup(); + settings.beginGroup( "/Toolbars" ); + // ... + settings.endGroup(); + settings.endGroup(); + \endcode + + You can get a list of entry-holding keys by calling entryList(), and + a list of key-holding keys using subkeyList(). + + \code + TQStringList keys = settings.entryList( "/MyApplication" ); + // keys contains 'background color' and 'foreground color'. + + TQStringList keys = settings.entryList( "/MyApplication/recent files" ); + // keys contains '1', '2' and '3'. + + TQStringList subkeys = settings.subkeyList( "/MyApplication" ); + // subkeys contains 'geometry' and 'recent files' + + TQStringList subkeys = settings.subkeyList( "/MyApplication/recent files" ); + // subkeys is empty. + \endcode + + Since settings for Windows are stored in the registry there are + some size limitations as follows: + \list + \i A subkey may not exceed 255 characters. + \i An entry's value may not exceed 16,300 characters. + \i All the values of a key (for example, all the 'recent files' + subkeys values), may not exceed 65,535 characters. + \endlist + + These limitations are not enforced on Unix or Mac OS X. + + \warning Creating multiple, simultaneous instances of TQSettings writing + to a text file may lead to data loss! This is a known issue which will + be fixed in a future release of TQt. + + \section1 Notes for Mac OS X Applications + + The location where settings are stored is not formally defined by + the CFPreferences API. + + At the time of writing settings are stored (either on a global or + user basis, preferring locally) into a plist file in \c + $ROOT/System/Library/Preferences (in XML format). TQSettings will + create an appropriate plist file (\c{com.<first group name>.plist}) + out of the full path to a key. + + For further information on CFPreferences see + \link http://developer.apple.com/documentation/CoreFoundation/Conceptual/CFPreferences/index.html + Apple's Specifications\endlink + + \section1 Notes for Unix Applications + + There is no universally accepted place for storing application + settings under Unix. In the examples the settings file will be + searched for in the following directories: + \list 1 + \i \c SYSCONF - the default value is \c INSTALL/etc/settings + \i \c /opt/MyCompany/share/etc + \i \c /opt/MyCompany/share/MyApplication/etc + \i \c $HOME/.qt + \endlist + When reading settings the files are searched in the order shown + above, with later settings overriding earlier settings. Files for + which the user doesn't have read permission are ignored. When saving + settings TQSettings works in the order shown above, writing + to the first settings file for which the user has write permission. + (\c INSTALL is the directory where TQt was installed. This can be + modified by using the configure script's -prefix argument ) + + If you want to put the settings in a particular place in the + filesystem you could do this: + \code + settings.insertSearchPath( TQSettings::Unix, "/opt/MyCompany/share" ); + \endcode + + But in practice you may prefer not to use a search path for Unix. + For example the following code: + \code + settings.writeEntry( "/MyApplication/geometry/width", width ); + \endcode + will end up writing the "geometry/width" setting to the file + \c{$HOME/.qt/myapplicationrc} (assuming that the application is + being run by an ordinary user, i.e. not by root). + + For cross-platform applications you should ensure that the + \link #sizelimit Windows size limitations \endlink are not exceeded. + + \warning TQSettings doesn't write the settings until it is destroyed so + you should construct the TQSettings object on the stack. +*/ + +/*! + \enum TQSettings::System + + \value Mac Macintosh execution environments + \value Unix Mac OS X, Unix, Linux and Unix-like execution environments + \value Windows Windows execution environments +*/ + +/*! + \enum TQSettings::Format + + \value Native Store the settings in a platform dependent location + \value Ini Store the settings in a text file +*/ + +/*! + \enum TQSettings::Scope + + \value Global Save settings as global as possible + \value User Save settings in user space +*/ + +#if defined(Q_OS_UNIX) +typedef int HANDLE; +#define Q_LOCKREAD F_RDLCK +#define Q_LOCKWRITE F_WRLCK +/* + Locks the file specified by name.

That is its whole purpose in life. + The TQCharRef becomes invalid once modifications are made to the + string: if you want to keep the character, copy it into a TQChar. + + Most of the TQChar member functions also exist in TQCharRef. + However, they are not explicitly documented here. + + \sa TQString::operator[]() TQString::at() TQChar +*/ + +/*! + \class TQChar qstring.h + \reentrant + \brief The TQChar class provides a lightweight Unicode character. + + \ingroup text + + Unicode characters are (so far) 16-bit entities without any markup + or structure. This class represents such an entity. It is + lightweight, so it can be used everywhere. Most compilers treat it + like a "short int". (In a few years it may be necessary to make + TQChar 32-bit when more than 65536 Unicode code points have been + defined and come into use.) + + TQChar provides a full complement of testing/classification + functions, converting to and from other formats, converting from + composed to decomposed Unicode, and trying to compare and + case-convert if you ask it to. + + The classification functions include functions like those in + ctype.h, but operating on the full range of Unicode characters. + They all return TRUE if the character is a certain type of + character; otherwise they return FALSE. These classification + functions are isNull() (returns TRUE if the character is U+0000), + isPrint() (TRUE if the character is any sort of printable + character, including whitespace), isPunct() (any sort of + punctation), isMark() (Unicode Mark), isLetter (a letter), + isNumber() (any sort of numeric character), isLetterOrNumber(), + and isDigit() (decimal digits). All of these are wrappers around + category() which return the Unicode-defined category of each + character. + + TQChar further provides direction(), which indicates the "natural" + writing direction of this character. The joining() function + indicates how the character joins with its neighbors (needed + mostly for Arabic) and finally mirrored(), which indicates whether + the character needs to be mirrored when it is printed in its + "unnatural" writing direction. + + Composed Unicode characters (like å) can be converted to + decomposed Unicode ("a" followed by "ring above") by using + decomposition(). + + In Unicode, comparison is not necessarily possible and case + conversion is very difficult at best. Unicode, covering the + "entire" world, also includes most of the world's case and sorting + problems. TQt tries, but not very hard: operator==() and friends + will do comparison based purely on the numeric Unicode value (code + point) of the characters, and upper() and lower() will do case + changes when the character has a well-defined upper/lower-case + equivalent. There is no provision for locale-dependent case + folding rules or comparison; these functions are meant to be fast + so they can be used unambiguously in data structures. (See + TQString::localeAwareCompare() though.) + + The conversion functions include unicode() (to a scalar), latin1() + (to scalar, but converts all non-Latin-1 characters to 0), row() + (gives the Unicode row), cell() (gives the Unicode cell), + digitValue() (gives the integer value of any of the numerous digit + characters), and a host of constructors. + + More information can be found in the document \link unicode.html + About Unicode. \endlink + + \sa TQString TQCharRef +*/ + +/*! + \enum TQChar::Category + + This enum maps the Unicode character categories. + + The following characters are normative in Unicode: + + \value Mark_NonSpacing Unicode class name Mn + + \value Mark_SpacingCombining Unicode class name Mc + + \value Mark_Enclosing Unicode class name Me + + \value Number_DecimalDigit Unicode class name Nd + + \value Number_Letter Unicode class name Nl + + \value Number_Other Unicode class name No + + \value Separator_Space Unicode class name Zs + + \value Separator_Line Unicode class name Zl + + \value Separator_Paragraph Unicode class name Zp + + \value Other_Control Unicode class name Cc + + \value Other_Format Unicode class name Cf + + \value Other_Surrogate Unicode class name Cs + + \value Other_PrivateUse Unicode class name Co + + \value Other_NotAssigned Unicode class name Cn + + + The following categories are informative in Unicode: + + \value Letter_Uppercase Unicode class name Lu + + \value Letter_Lowercase Unicode class name Ll + + \value Letter_Titlecase Unicode class name Lt + + \value Letter_Modifier Unicode class name Lm + + \value Letter_Other Unicode class name Lo + + \value Punctuation_Connector Unicode class name Pc + + \value Punctuation_Dash Unicode class name Pd + + \value Punctuation_Open Unicode class name Ps + + \value Punctuation_Close Unicode class name Pe + + \value Punctuation_InitialQuote Unicode class name Pi + + \value Punctuation_FinalQuote Unicode class name Pf + + \value Punctuation_Other Unicode class name Po + + \value Symbol_Math Unicode class name Sm + + \value Symbol_Currency Unicode class name Sc + + \value Symbol_Modifier Unicode class name Sk + + \value Symbol_Other Unicode class name So + + + There are two categories that are specific to TQt: + + \value NoCategory used when TQt is dazed and confused and cannot + make sense of anything. + + \value Punctuation_Dask old typo alias for Punctuation_Dash + +*/ + +/*! + \enum TQChar::Direction + + This enum type defines the Unicode direction attributes.

It is legal for the \c + {const char *} parameter to be 0. If the \c {const char *} is not + '\0'-terminated, the results are undefined. Functions that copy + classic C strings into a TQString will not copy the terminating + '\0' character. The TQChar array of the TQString (as returned by + unicode()) is generally not terminated by a '\0'. If you need to + pass a TQString to a function that retquires a C '\0'-terminated + string use latin1(). + + \keyword TQString::null + A TQString that has not been assigned to anything is \e null, i.e. + both the length and data pointer is 0. A TQString that references + the empty string ("", a single '\0' char) is \e empty. Both null + and empty TQStrings are legal parameters to the methods. Assigning + \c{(const char *) 0} to TQString gives a null TQString. For + convenience, \c TQString::null is a null TQString. When sorting, + empty strings come first, followed by non-empty strings, followed + by null strings. We recommend using \c{if ( !str.isNull() )} to + check for a non-null string rather than \c{if ( !str )}; see \l + operator!() for an explanation. + + Note that if you find that you are mixing usage of \l TQCString, + TQString, and \l TQByteArray, this causes lots of unnecessary + copying and might indicate that the true nature of the data you + are dealing with is uncertain. If the data is '\0'-terminated 8-bit + data, use \l TQCString; if it is unterminated (i.e. contains '\0's) + 8-bit data, use \l TQByteArray; if it is text, use TQString. + + Lists of strings are handled by the TQStringList class. You can + split a string into a list of strings using TQStringList::split(), + and join a list of strings into a single string with an optional + separator using TQStringList::join(). You can obtain a list of + strings from a string list that contain a particular substring or + that match a particular \link qregexp.html regex\endlink using + TQStringList::grep(). + + <b>Note for C programmers</b> + + Due to C++'s type system and the fact that TQString is implicitly + shared, TQStrings can be treated like ints or other simple base + types. For example: + + \code + TQString boolToString( bool b ) + { + TQString result; + if ( b ) + result = "True"; + else + result = "False"; + return result; + } + \endcode + + The variable, result, is an auto variable allocated on the stack. + When return is called, because we're returning by value, The copy + constructor is called and a copy of the string is returned. (No + actual copying takes place thanks to the implicit sharing, see + below.) + + Throughout TQt's source code you will encounter TQString usages like + this: + \code + TQString func( const TQString& input ) + { + TQString output = input; + // process output + return output; + } + \endcode + + The 'copying' of input to output is almost as fast as copying a + pointer because behind the scenes copying is achieved by + incrementing a reference count. TQString (like all TQt's implicitly + shared classes) operates on a copy-on-write basis, only copying if + an instance is actually changed. + + If you wish to create a deep copy of a TQString without losing any + Unicode information then you should use TQDeepCopy. + + \sa TQChar TQCString TQByteArray TQConstString +*/ + +/*! \enum TQt::ComparisonFlags +\internal +*/ +/*! + \enum TQt::StringComparisonMode + + This enum type is used to set the string comparison mode when + searching for an item.

The + 128-bit value of a UUID is generated by an algorithm that + guarantees that the value is unique. + + In TQt, UUIDs are wrapped by the TQUuid struct which provides + convenience functions for handling UUIDs. Most platforms provide a + tool to generate new UUIDs, for example, uuidgen and guidgen. + + UUIDs generated by TQUuid, are based on the \c Random version of the + \c DCE (Distributed Computing Environment) standard. + + UUIDs can be constructed from numeric values or from strings, or + using the static createUuid() function.

Use wakeOne() to wake one randomly selected event or + wakeAll() to wake them all. For example, say we have three tasks + that should be performed every time the user presses a key; each + task could be split into a thread, each of which would have a + run() body like this: + + \code + TQWaitCondition key_pressed; + + for (;;) { + key_pressed.wait(); // This is a TQWaitCondition global variable + // Key was pressed, do something interesting + do_something(); + } + \endcode + + A fourth thread would read key presses and wake the other three + threads up every time it receives one, like this: + + \code + TQWaitCondition key_pressed; + + for (;;) { + getchar(); + // Causes any thread in key_pressed.wait() to return from + // that method and continue processing + key_pressed.wakeAll(); + } + \endcode + + Note that the order the three threads are woken up in is + undefined, and that if some or all of the threads are still in + do_something() when the key is pressed, they won't be woken up + (since they're not waiting on the condition variable) and so the + task will not be performed for that key press.
