It is generated by the ui2uib converter and understood by + QWidgetFactory; in a future version, it might also be understood + by a uib2ui converter. Experiments show that .uib files are about + 2.5 times faster to load and 6 times smaller than .ui files. + + The .uib format, unlike the .ui format, is internal to Trolltech + and is not officially documented; it is assumed that anybody who + needs to understand the file format can read the ui2uib and + QWidgetFactory source code, with some guidance. And here's some + guidance. + + A .uib file starts with a 32-bit magic number that allows + QWidgetFactory to determine the file type. The magic number is + followed by '\n' (0x0a) and '\r' (0x0d), which ensure that the + file wasn't corrupted during transfer between different + platforms. For example, transferring a .ui file from Windows to + Unix using FTP with type ASCII will produce a file with '\r\n\r' + in place of '\n\r'. This is followed by the QDataStream format + version number used. + + The rest of the file is made up of blocks, each of which starts + with a block type (Block_XXX) and a block length. Block_Intro and + Block_Widget are mandatory; the others are optional. + QWidgetFactory makes certain assumptions about the order of the + blocks; for example, it expects Block_String before any other + block that refers to a string and Block_Images before + Block_Widget. The order generated by ui2uib is one of the orders + that make sense. Just after the last block, a Block_End marker + indicates the end of the file. + + The division of .uib files into blocks corresponds grossly to the + division of .ui files in top-level XML elements. Thus, + Block_Widget corresponds to <widget> and Block_Toolbars to + <toolbars>. The internal organization of each block also mimics + the organization of the corresponding XML elements. + + These are the major differences, all of which contribute to + making .uib files more compact: + + 1. The strings are gathered in Block_Strings, a string-table. + When a string is needed later, it is referenced by a 32-bit + index into that table. The UicStringTable class makes the + whole process of inserting and looking up strings very + simple. The advantage of this scheme is that if a string is + used more than once, it is stored only once. Also, the + string-table is preinitialized with very common strings, so + that these need not be stored along with .uib files. + + 2. QObjects are referred to by index in a table rather than by + name. The table itself is not stored in the .uib file; it is + rather build dynamically by ui2uib and QWidgetFactory as new + objects are specified. In ui2uib, the table is represented by + a UibIndexMap object; in QWidgetFactory, a plain array of + QObject pointers suffices. + + 3. The data is packed to take as little place as possible, + without slowing down QLayoutFactory too much. For example, an + index into the string-table is a 32-bit integer, but in + practice it is rarely above 65534, so only 16 bits are used + for them; when an index above 65534 is met, the index is + saved as 65535 followed by the 32-bit index, for a total of + 48 bits. + + 4. The name of a signal or slot and its signature are saved + separately. That way, if a signal 'foo(const QString&)' is + connected to a slot 'bar(const QString&)', the string-table + will only contain 'foo', 'bar', and '(const QString&)', + instead of the longer 'foo(const QString&)' and 'bar(const + QString&)'. The signatures are normalized beforehand to + ensure that trivial spacing problems don't result in multiple + string-table entries. + + 5. In a signal-to-slot connection, a sender, signal, receiver, + or slot is not repeated if it's the same as for the previous + connection. Bit flags indicate what is repeated and what is + specified. + + 6. Some of the information stored in a .ui file is useful only + by uic, not to QLayoutFactory. That information is, for now, + not taken along in the .uib file. Likewise, needless + QLayoutWidget objects are not taken along. + + The arbitrary constants related to the .uib file formats are + defined in uib.h. Constants such as Block_Actions and + Object_SubWidget are given values such as 'A' and 'W' to make + .uib files easier to read in a hexadecimal editor. + + The file format isn't designed to be extensible. Any extension + that prevents an older version of QLayoutWidget of reading the + file correctly must have a different magic number. The plan is to + use UibMagic + 1 for version 2, UibMagic + 2 for version 3, etc. +*/ + +static QCString layoutForTag( const QString& tag ) +{ + if ( tag == "grid" ) { + return "QGridLayout"; + } else if ( tag == "hbox" ) { + return "QHBoxLayout";
