<p> <p>
|
||||
You're probably looking at this page because you want to port
|
||||
your application from Qt 1.x to Qt 2.x, but to be sure, let's
|
||||
review the good reasons to do this:
|
||||
<ul>
|
||||
<li>To get access to all the new Qt 2.x features like the rich text
|
||||
HTML subset for formatted labels, tooltips, online help etc.
|
||||
and the much easier to use layout classes and widgets.
|
||||
<li>To make your application truly international, with support
|
||||
for Unicode and translations for the languages of the world.
|
||||
<li>To allow your application to fit into the new look of the
|
||||
Unix desktop with configurable, very powerful "themes". The
|
||||
extended style system also integrates Qt applications better
|
||||
on MS-Windows desktops. Qt will automatically chose the right
|
||||
colors and fonts and obey global system setting changes.
|
||||
<li>To stay up-to-date with the version of Qt that gets all the
|
||||
new features and bug-fixes.
|
||||
<li>To get more speed and smoother widgets display with all the
|
||||
new anti-flicker changes in Qt.
|
||||
<li>Most of all though, you want to port to Qt 2.x
|
||||
so that your Wheel Mouse works!
|
||||
</ul>
|
||||
<p> <p>
|
||||
The Qt 2.x series is not binary compatible with the 1.x series.
|
||||
This means programs compiled for Qt 1.x must be recompiled to work
|
||||
with Qt 2.x. Qt 2.x is also not completely <em>source</em> compatible
|
||||
with 1.x, however all points of incompatibility cause
|
||||
compiler errors (rather than mysterious results), or produce run-time
|
||||
messages. The result is that Qt 2.x includes many additional features,
|
||||
discards obsolete functionality that is easily converted to use the new
|
||||
features, and that porting an application from Qt 1.x to Qt 2.x is
|
||||
a simple task well worth the amount of effort required.
|
||||
<p> To port code using Qt 1.x to use Qt 2.x:
|
||||
<p> <ul>
|
||||
<li> Briefly read the porting notes below to get an idea of what to expect.
|
||||
<li> Be sure your code compiles and runs well on all your target platforms with Qt 1.x.
|
||||
<li> Recompile with Qt 2.x. For each error, search below for related
|
||||
identifiers (eg. function names, class names) - this documented is
|
||||
structured to mention all relevant identifiers to facilitate such
|
||||
searching, even if that makes it a little verbose.
|
||||
<li> If you get stuck, ask on the qt-interest mailing list, or
|
||||
Trolltech Technical Support if you're a Professional Edition
|
||||
licensee.
|
||||
</ul>
|
||||
<p> Many very major projects, such as <a href="http://www.kde.org/">KDE</a>
|
||||
have been port, so there is plenty of expertise in the collective conscious
|
||||
that is the Qt Developer Community!

<p> <h3><a name="Namespace">Namespace</a></h3>
|
||||
<p> <p> Qt 2.x is namespace-clean, unlike 1.x. Qt now uses very few
|
||||
global identifiers. Identifiers like <code>red, blue, LeftButton,
|
||||
AlignRight, Key_Up, Key_Down, NoBrush</code> etc. are now part of a
|
||||
special class <code>Qt</code> (defined in qnamespace.h),
|
||||
which is inherited by
|
||||
most Qt classes. Member functions of classes that inherit from <a href="qwidget.html">QWidget</a>,
|
||||
etc. are totally unaffected, but code that is
|
||||
<em>not</em> in functions of classes inherited from <code>Qt</code>,

|

<p> Compiling with -DQT1COMPATIBILITY will help you get going with Qt 2.x
|
||||

<p> <h3><a name="DefaultParent">No Default 0 Parent Widget</a></h3>
|
||||
<p> In Qt 1.x, all widget constructors were defined with a default value
|
||||
of 0 for the parent widget. However, only the main window of the
|
||||
application should be created with a 0 parent, all other widgets
|
||||
should have parents. Having the 0 default made it too simple to create
|
||||
bugs by forgetting to specify the parent of non-mainwindow
|
||||
widgets. Such widgets would typically never be deleted (causing memory
|
||||
leaks), and they would become top-level widgets, confusing the window
|
||||
managers. Therefore, in Qt 2.x the 0 default parent has been removed
|
||||
for the widget classes that are not likely to be used as main windows.
|
||||
<p> Note also that programs no longer need (or should) use 0 parent just
|
||||
to indicate that a widget should be top-level. See
|
||||
<pre> QWidget::isTopLevel() </pre>
|
||||
for details. See also the notes about
|
||||
<a href="#QMenuData">QPopupMenu</a> and <a href="#QDialog">QDialog</a>

|
||||
<p> <h3><a name="Virtual">Virtual Functions</a></h3>
|
||||
<p> <p> Some virtual functions have changed signature in Qt 2.x.
|
||||
If you override them in derived classes, you must change the signature
|
||||
of your functions accordingly.

<p> This is one class of changes that are

these function names in your header files, eg.

<p> <pre>

egrep -w 'setStyle|addColumn|setColumnText|setText...' *.h
|

the subclasses such as <a href="qdict.html">QDict</a> and QList.
|

<p> <p> The macro-based Qt collection classes are obsolete; use the

template-based classes instead. Simply remove includes of qgeneric.h and
|
||||
replace e.g. Q_DECLARE(<a href="qcache.html">QCache</a>,QPixmap) with QCache<QPixmap>.
|
||||
<p> <p> The GCI global typedef is replaced by QCollection::Item. Only if you
|
||||
make your own subclasses of the undocumented generic collection classes
|
||||
will you have GCI in your code.
|

This change has been made to avoid collisions with other namespaces.

the QT_NO_DEBUG macro defined.
|

<p> <h3><a name="QString">QString</a></h3>
|
||||
<p> <a href="qstring.html">QString</a> has undergone major changes internally, and although it is highly
|
||||
backward compatible, it is worth studying in detail when porting to Qt 2.x.
|
||||
The Qt 1.x QString class has been renamed to <a href="qcstring.html">QCString</a> in Qt 2.x, though if
|
||||
you use that you will incur a performance penalty since all Qt functions
|
||||
that took const char* now take const QString&.
|
||||
<p> <p>
|
||||
To take full advantage of the new <a href="i18n.html#internationalization">Internationalization</a>
|
||||
functionality in Qt 2.x, the following steps are required:
|
||||
<p> <ul>
|
||||
<li> Start converting all uses of "const char*" in parameters to
|
||||
"const QString&" - this can often be done mechanically, eg.
|
||||
using Perl. Convert usage of char[] for temporary string
|
||||
building to QString (much software already uses QString for
|
||||
this purpose as it offers many more facilities).
|
||||
<p> If you find that you are mixing usage of QCString, QString,
|
||||
and <a href="qbytearray.html">QByteArray</a>, 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 NUL-terminated
|
||||
8-bit data, use QCString; if it is unterminated (ie.
|
||||
contains NULs) 8-bit data, use QByteArray; if it is text,
|
||||
use <a href="qstring.html">QString</a>.
|
||||
</p>
|
||||
<li> Put a breakpoint in <pre> QString::latin1()</pre>
|
||||
|
||||
to catch places where
|
||||
Unicode information is being converted to ASCII (loosing
|
||||
information if your user in not using Latin1). Qt has
|
||||
a small number of calls to this - ignore those. As a stricter
|
||||
alternative, compile your code with QT_NO_ASCII_CAST defined,
|
||||
which hides the automatic conversion of QString to const char*,
|
||||
so you can catch problems at compile time.
|
||||
</p>
|
||||
<li> See the Qt <a href="i18n.html">Internationalization page</a>
|
||||
for information about the full process of internationalizing
|
||||
your software.
|
||||
</ul>

<p> <dl compact>
|
||||
<dt><b>Unicode</b></dt>
|
||||
<dd>
|
||||
Qt now uses Unicode throughout.
|
||||
data() now returns a <em>const</em> reference to an ASCII version
|
||||
of the string - you cannot directly access the
|
||||
string as an array of bytes, because it isn't one. Often, latin1() is
|
||||
what you want rather than data(), or just leave it to convert to
|
||||
const char* automatically. data() is only used now to aide porting to Qt 2.x,
|
||||
and ideally you'll only need latin1() or implicit conversion when interfacing
|
||||
to facilities that do not have Unicode support.
|
||||
<p> <dt><b>Automatic-expanding</b></dt>
|
||||
<dd>
|
||||
A big advantage of the new <a href="qstring.html">QString</a> is that it automatically expands
|

when you write to an indexed position.
|
||||
<p> <dt><b>QChar and <a href="qcharref.html">QCharRef</a></b></dt>
|
||||
<dd>
|

<a href="qchar.html">QChar</a> are the Unicode characters that make up a QString. A QCharRef is
|
||||
a temporary reference to a QChar in a QString that when assigned to
|
||||
ensures that the <a href="shclass.html#implicit-sharing">implicit sharing</a> semantics of the QString are maintained.
|
||||
You are unlikely to use QCharRef in your own code - but so that you
|
||||
understand compiler error messages, just know that <tt>mystring[123]</tt>
|
||||
is a QCharRef whenever <tt>mystring</tt> is not a constant string. A QCharRef
|
||||
has basically the same functionality as a QChar, except it is more restricted
|
||||
in what you can assign to it and cast it to (to avoid programming errors).
|
||||
<p> <dt><b>Use QString</b></dt>
|
||||
<dd>
|

Try to always use QString. If you <em>must</em>, use <a href="qcstring.html">QCString</a> which is the
|

old implementation from Qt 1.x.
|
||||
<p> <dt><b>Unicode vs. ASCII</b></dt>
|

<dd>
|

Every conversion to and from ASCII is wasted time, so try to use <a href="qstring.html">QString</a>

as much as possible rather than const char*. This also ensures you have

full 16-bit support.
|

<p> <dt><b>Convertion to ASCII</b></dt>
|

<dd>
|

The return value from operator const char*() is transient - don't expect
|

it to remain valid while you make deep function calls.

It is valid for as long as you don't modify or destroy the QString.
|

<p> <dt><b>QString is simpler</b></dt>
|

<dd>

Expect your code to become simpler with the new QString, especially

places where you have used a char* to wander over the string rather

than using indexes into the string.

<p> <dt><b>Some hacks don't work</b></dt>
|

<dd>

This hack:

use_sub_string( &my_string[index] )

should be replaced by:

use_sub_string( my_string.mid(index) )
|

<p> <dt><b>QString(const char*, int) is removed</b></dt>
|
||||
<dd>
|
||||
The QString constructor taking a const char* and an integer is removed.
|
||||
Use of this constructor was error-prone, since the length included the
|
||||
'\0' terminator. Use <a href="qstring.html#left">QString::left</a>(int) or <a href="qstring.html#fromLatin1">QString::fromLatin1</a>( const char*,
|
||||
int ) -- in both cases the int parameter signifies the number of characters.
|
||||
<p> <dt><b>QString(int) is private</b></dt>
|
||||
<dd>
|
||||
The <a href="qstring.html">QString</a> constructor taking an integer is now private. This function
|
||||
is not meaningful anymore, since QString does all space allocation
|
||||
automatically. 99% of cases can simple be changed to use the
|
||||
default constructor, QString().
|
||||
<p>
|
||||
In Qt 1.x the constructor was used in two ways: accidentally,
|
||||
by attempting to convert a char to a QString (the char converts to int!) -
|
||||
giving strange bugs, and as a way to make a QString big enough prior to
|
||||
calling <pre> QString::sprintf()</pre>
|
||||
. In Qt 2.x, the accidental bug case is
|
||||
prevented (you will get a compilation error) and QString::sprintf has
|
||||
been made safe - you no longer need to pre-allocate space (though for
|
||||
other reasons, sprintf is still a poor choice - eg. it doesn't pass Unicode).
|
||||
The only remaining common case is conversion of 0 (NULL) to QString, which
|
||||
would usually give expected results in Qt 1.x. For Qt 2.x the correct
|
||||
syntax is to use <a href="qstring.html#QString-null">QString::null</a>, though note that
|
||||
the default constructor, QString(), creates a null string too.
|
||||
Assignment of 0 to a <a href="qstring.html">QString</a> is ambiguous - assign
|
||||
QString::null; you'll mainly find these in code that has been converted
|
||||
from const char* types to QString.
|
||||
This also prevents a common error case from Qt 1.x - in
|
||||
that version, mystr = 'X' would <em>not</em> produce the expected
|
||||
results and was always a programming error; in Qt 2.x, it works - making
|
||||
a single-character string.

<p> <dt><b>Optimize with Q2HELPER</b></dt>

<p> <dt><b>QString::detach() is obsolete and removed</b></dt>

You may find yourself needing latin1() for passing to the operating system

This means that inserting a 0-character

in the middle of the string does <em>not</em> change the length(). ie.
|

<pre>
|

<a href="qstring.html">QString</a> s = "fred";
|

s[1] = '\0';
|

// s.<a href="qstring.html#latin1">latin1</a>() == "fred"

<a href="qstring.html">QString</a> s(2);
|

s[0] = '?';
|

s[1] = 0;
|

</pre>
|

|

This creates a string 2 characters long.
|

To find these problems while converting, you might like to
|

add <a href="qapplication.html#Q_ASSERT">Q_ASSERT</a>(strlen(d->ascii)==d->len) inside

<p> <dt><b>QString or Standard C++ string?</b></dt>
|

<dd>
|

<p>
|
||||
The Standard C++ Library string is not Unicode. Nor is wstring defined
|
||||
to be so (for the small number of platforms where it is defined at all).
|
||||
This is the same mistake made over and over
|
||||
in the history of C - only when non-8-bit characters are <em>the norm</em>
|
||||
do programmers find them usable. Though it is possible to convert between
|
||||
string and <a href="qstring.html">QString</a>, it is less efficient than using QString throughout.
|
||||
For example, when using:
|
||||
<pre>
|
||||
QLabel::<a href="qlabel.html#setText">setText</a>( const <a href="qstring.html">QString</a>& )
|
||||
</pre>
|
||||
|
||||
if you use string, like this:
|
||||
<pre>
|
||||
void myclass::dostuffwithtext( const string& str )
|
||||
{
|
||||
mylabel.setText( QString(str.c_str()) );
|
||||
}
|
||||
</pre>
|
||||
|
||||
that will create a (ASCII only) copy of str, stored in mylabel.
|
||||
But this:
|
||||
<pre>
|
||||
void myclass::dostuffwithtext( const <a href="qstring.html">QString</a>& str )
|
||||
{
|
||||
mylabel.setText( str );
|
||||
}
|
||||
</pre>
|
||||
|
||||
will make an <a href="shclass.html#implicitly-shared">implicitly shared</a> reference to str in the <a href="qlabel.html">QLabel</a> - no copying
|
||||
at all. This function might be 10 nested function calls away from something
|
||||
like this:
|
||||
<pre>
|
||||
void toplevelclass::initializationstuff()
|
||||
{
|
||||
doStuff( tr("Okay") );
|
||||
}
|
||||
</pre>
|
||||
|
||||
At this point, in Qt 2.x, the tr() does a very fast dictionary lookup
|
||||
through memory-mapped message files, returning some Unicode <a href="qstring.html">QString</a> for
|
||||
the appropriate language (the default being to just make a QString out
|
||||
of the text, of course - you're not <em>forced</em> to use any of these
|
||||
features), and that <em>same</em> memory mapped Unicode will be passed
|
||||
though the system. All occurrences of the translation of "Okay" can
|
||||
potentially be shared.

the functions <a href="qcolor.html#qRgba">qRgba</a>(int,int,int,int) and <a href="qcolor.html#qAlpha">qAlpha</a>(QRgb). Note also that
|
||||
<a href="qcolor.html#pixel">QColor::pixel</a>() does <i>not</i> return a QRgb (it never did on all platforms,
|
||||
but your code may have assumed so on your platform) - this may also produce
|
||||
strange color results - use <a href="qcolor.html#rgb">QColor::rgb</a>() if you want a QRgb.
|
||||
<p> <h3><a name="QDataStream">QDataStream</a></h3>
|
||||
<p> <p>The QDatastream serialization format of most Qt classes is changed
|
||||
in Qt 2.x. Use <pre> QDataStream::setVersion( 1 )</pre>
|
||||
to get a
|
||||
datastream object that can read and write Qt 1.x format data streams.
|
||||
<p> <p>If you want to write Qt 1.x format datastreams, note the following
|
||||
compatibility issues:
|
||||
<ul>
|
||||
<li>QString: Qt 1.x has no Unicode support, so strings will be
|
||||
serialized by writing the classic C string returned by <pre>
|
||||
QString::<a href="qstring.html#latin1">latin1</a>().</pre>
|
||||
|
||||
<li><a href="#QPoint">QPoint & al.</a>: Coordinates will be
|
||||
truncated to the Qt 1.x 16 bit format.
|
||||
</ul>
|
||||
<p> <h3><a name="QWidget">QWidget</a></h3>
|
||||
<p> <h4>QWidget::recreate()</h4>
|
||||
<p>
|
||||
This function is now called <a href="qwidget.html#reparent">reparent()</a>.
|
||||
<p> <h4>QWidget::setAcceptFocus(bool)</h4>
|
||||
<p>
|
||||
This function is removed.
|
||||
Calls like QWidget::setAcceptFocus(TRUE) should be replaced by
|
||||
<pre> QWidget::setFocusPolicy(StrongFocus)</pre>
|
||||
, and
|
||||
calls like QWidget::setAcceptFocus(FALSE) should be replaced by
|
||||
<pre> QWidget::setFocusPolicy(NoFocus)</pre>
|
||||
.
|
||||
Additional policies are TabFocus and ClickFocus.
|
||||
<p> <h4>QWidget::paintEvent()</h4>
|
||||
<p>
|
||||
paintEvent(0) is not permitted - subclasses need not check for
|
||||
a null event, and might crash.
|
||||
Never pass 0 as the argument to paintEvent(). You probably
|
||||
just want repaint() or update() instead.
|
||||
<p>
|
||||
When processing a paintEvent, painting is only permitted within
|
||||
the update region specified in the event. Any painting outside will be
|
||||
clipped away. This shouldn't break any code (it was always like this
|
||||
on MS-Windows) but makes many explicit calls to
|
||||
<a href="qpainter.html#setClipRegion">QPainter::setClipRegion</a>() superfluous. Apart from the improved
|
||||
consistency, the change is likely to reduce flicker and to make Qt
|
||||
event slightly faster.
|
||||
<p> <h3><a name="QIODevice">QIODevice</a></h3>
|
||||
<p>
|
||||
The protected member QIODevice::index is renamed to QIODevice::ioIndex
|
||||
to avoid warnings and to allow compilation with bad C libraries that
|
||||
#define index to strchr. If you have made a subclass of <a href="qiodevice.html">QIODevice</a>,
|
||||
check every occurrence of the string "index" in the implementation, since
|
||||
a compiler will not always catch cases like <pre>(uint)index</pre>
|
||||
|
||||
that need to be changed.
|
||||
<p> <h3><a name="QLabel">QLabel</a></h3>
|
||||
<p> <h4><pre> QLabel::setMargin()</pre>
|
||||
</h4>
|
||||
<p>
|
||||
<pre> QLabel::setMargin()</pre>
|
||||
and<pre> QLabel::margin()</pre>
|
||||
|
||||
have been renamed to <pre> QLabel::setIndent()</pre>
|
||||
and
|
||||
<pre> QLabel::indent()</pre>
|
||||
, respectively. This was done to avoid
|
||||
collision with <a href="qframe.html#setMargin">QFrame::setMargin</a>(), which is now virtual.
|
||||
<p> <h4><pre> QLabel::setMovie()</pre>
|
||||
</h4>
|
||||
<p>
|
||||
Previously, setting a movie on a label cleared the value of text().
|
||||
Now it doesn't. If you somehow used <tt>QLabel::text()</tt>
|
||||
to detect if a
|
||||
movie was set, you might have trouble. This is unlikely.
|
||||
<p> <h3><a name="QDialog">QDialog</a></h3>
|
||||
<p> <p> The semantics of the parent pointer changed for modeless dialogs:
|
||||
In Qt-2.x, dialogs are always top level windows. The parent, however,
|
||||
takes the ownership of the dialog, i.e. it will delete the dialog at
|
||||
destruction if it has not been explicitly deleted
|
||||
already. Furthermore, the window system will be able to tell that both
|
||||
the dialog and the parent belong together. Some X11 window managers
|
||||
will for instance provide a common taskbar entry in that case.
|
||||
<p> <p>
|
||||
If the dialog belongs to a top level main window
|
||||
of your application, pass this main window as parent to the dialog's
|
||||
constructor. Old code (with 0 pointer) will still run. Old code that
|
||||
included QDialogs as child widgets will no longer work (it never really did).
|
||||
If you think you might be doing this, put a breakpoint in
|
||||
<a href="qdialog.html#QDialog">QDialog::QDialog</a>() conditional on parent not being 0.
|
||||
<p> <h3><a name="QStrList">QStrList</a></h3>
|
||||
<p> Many methods that took a <a href="qstrlist.html">QStrList</a> can now instead take a <a href="qstringlist.html">QStringList</a>,
|
||||
which is a real list of <a href="qstring.html">QString</a> values.
|
||||
<p> To use QStringList rather than QStrList, change loops that look like this:
|
||||
<pre>
|
||||
<a href="qstrlist.html">QStrList</a> list = ...;
|
||||
const char* s;
|
||||
for ( s = list.<a href="qptrlist.html#first">first</a>(); s; s = list.<a href="qptrlist.html#next">next</a>() ) {
|
||||
process(s);
|
||||
}
|
||||
</pre>
|
||||
|
||||
to be like this:
|
||||
<pre>
|
||||
<a href="qstringlist.html">QStringList</a> list = ...;
|
||||
QStringList::ConstIterator i;
|
||||
for ( i = list.<a href="qvaluelist.html#begin">begin</a>(); i != list.<a href="qvaluelist.html#end">end</a>(); ++i ) {
|
||||
process(*i);
|
||||
}
|
||||
</pre>
|
||||
|
||||
<p> In general, the QStrList functions are less efficient, building a temporary QStringList.
|
||||
<p> The following functions now use QStringList rather than QStrList
|
||||
for return types/parameters.
|
||||
<p> <ul>
|
||||
<li><tt>void <a href="qfiledialog.html#setFilters">QFileDialog::setFilters</a>(const <a href="qstrlist.html">QStrList</a>&)</tt>
|
||||
becomes <tt>void QFileDialog::setFilters(const <a href="qstringlist.html">QStringList</a>&)</tt>
|
||||
<li><tt>QStrList <a href="qfiledialog.html#getOpenFileNames">QFileDialog::getOpenFileNames</a>(...)</tt>
|
||||
becomes <tt>QStringList QFileDialog::getOpenFileNames(...)</tt>
|
||||
<li><tt>bool QUrlDrag::decodeLocalFiles(<a href="qmimesource.html">QMimeSource</a>*, QStrList&)</tt>
|
||||
becomes <tt>bool <a href="quridrag.html#decodeLocalFiles">QUriDrag::decodeLocalFiles</a>(QMimeSource*, QStringList&)</tt>
|
||||
<li><tt>const QStrList *QDir::entryList(...) const</tt>
|
||||
becomes <tt>QStringList <a href="qdir.html#entryList">QDir::entryList</a>(...) const</tt>
|
||||
(note that the return type is no longer a pointer). You may also
|
||||
choose to use encodedEntryList().
|
||||
</ul>
|
||||
<p> The following functions are added:
|
||||
<ul>
|
||||
<li><tt>QComboBox::insertStringList(const QStringList &, int index=-1)</tt>
|
||||
<li><tt>QListBox::insertStringList(const QStringList &,int index=-1)</tt>
|
||||
</ul>
|
||||
<p> The rarely used static function <tt>void
|
||||
QFont::listSubstitutions(<a href="qstrlist.html">QStrList</a>*)</tt> is replaced by <tt>QStringList
|
||||
<a href="qfont.html#substitutions">QFont::substitutions</a>()</tt>.
|
||||
<p> <h3><a name="QLayout">QLayout</a></h3>
|
||||
<p> <p> Calling resize(0,0) or resize(1,1) will no longer work magically.
|
||||
Remove all such calls. The default size of top level widgets will be their
|
||||
<a href="qwidget.html#sizeHint">sizeHint()</a>.
|
||||
<p> <p> The default implementation of <a href="qwidget.html#sizeHint">QWidget::sizeHint</a>() will no longer
|
||||
return just an invalid size; if the widget has a layout, it will return
|
||||
the layout's preferred size.
|
||||
<p> <p> The special maximum MaximumHeight/Width is now QWIDGETSIZE_MAX,
|
||||
not QCOORD_MAX.
|
||||
<p> <p> <a href="qboxlayout.html#addWidget">QBoxLayout::addWidget()</a>
|
||||
now interprets the <em>alignment</em> parameter more aggressively. A
|
||||
non-default alignment now indicates that the widget should not grow to
|
||||
fill the available space, but should be sized according to sizeHint().
|
||||
If a widget is too small, set the alignment to 0. (Zero indicates no
|
||||
alignment, and is the default.)
|
||||
<p> <p> The class QGManager is removed. Subclasses of <a href="qlayout.html">QLayout</a> need to be rewritten
|
||||
to use the new, much simpler <a href="qlayout.html">QLayout API</a>.
|
||||
<p> <p> For typical layouts, all use of
|
||||
<a href="qwidget.html#setMinimumSize">setMinimumSize()</a>
|
||||
and
|
||||
<a href="qwidget.html#setFixedSize">setFixedSize()</a>
|
||||
can be removed.
|
||||
<a href="qlayout.html#activate">activate()</a> is no longer necessary.
|
||||
<p> <p>
|
||||
You might like to look at the <a href="qgrid.html">QGrid</a>, <a href="qvbox.html">QVBox</a>, and <a href="qhbox.html">QHBox</a> widgets - they offer
|
||||
a simple way to build nested widget structures.
|
||||
<p> <h3><a name="QListView">QListView</a></h3>
|
||||
<p> <p>In Qt 1.x mouse events to the viewport where redirected to the
|
||||
event handlers for the listview; in Qt 2.x, this functionality is
|
||||
in <a href="qscrollview.html">QScrollView</a> where mouse (and other position-oriented) events are
|
||||
redirected to viewportMousePressEvent() etc, which in turn translate
|
||||
the event to the coordinate system of the contents and call
|
||||
contentsMousePressEvent() etc, thus providing events in the most
|
||||
convenient coordinate system. If you overrode QListView::MouseButtonPress(),
|
||||
<a href="qwidget.html#mouseDoubleClickEvent">QListView::mouseDoubleClickEvent</a>(), <a href="qwidget.html#mouseMoveEvent">QListView::mouseMoveEvent</a>(), or
|
||||
<a href="qwidget.html#mouseReleaseEvent">QListView::mouseReleaseEvent</a>() you must instead override
|
||||
viewportMousePressEvent(),
|
||||
viewportMouseDoubleClickEvent(), viewportMouseMoveEvent(), or
|
||||
viewportMouseReleaseEvent() respectively. New code will usually override
|
||||
contentsMousePressEvent() etc.
|
||||
<p> <p>The signal <a href="qlistview.html#selectionChanged">QListView::selectionChanged</a>(<a href="qlistviewitem.html">QListViewItem</a> *) can now be
|
||||
emitted with a null pointer as parameter. Programs that use the
|
||||
argument without checking for 0, may crash.
|
||||
<p> <h3><a name="QMultiLineEdit">QMultiLineEdit</a></h3>
|
||||
<p> <p>
|
||||
The protected function
|
||||
<pre> QMultiLineEdit::textWidth(QString*)</pre>
|
||||
|
||||
changed to
|
||||
<pre> QMultiLineEdit::textWidth(const <a href="qstring.html">QString</a>&)</pre>
|
||||
.
|
||||
This is unlikely to be a problem, and you'll get a compile error
|
||||
if you called it.
|
||||
<p> <h3><a name="QClipboard">QClipboard</a></h3>
|
||||
<p> <p>
|
||||
<pre> QClipboard::pixmap()</pre>
|
||||
now returns a <a href="qpixmap.html">QPixmap</a>, not a QPixmap*.
|
||||
The pixmap
|
||||
will be <a href="qpixmap.html#isNull">null</a> if no pixmap is on the
|
||||
clipboard. <a href="qclipboard.html">QClipboard</a> now offers powerful MIME-based types on the
|
||||
clipboard, just like drag-and-drop (in fact, you can reuse most of your
|
||||
drag-and-drop code with clipboard operations).
|
||||
<p> <h3><a name="QDropSite">QDropSite</a></h3>
|
||||
<p> <P>
|
||||
QDropSite is obsolete. If you simply passed <tt>this</tt>, just remove
|
||||
the inheritance of QDropSite and call
|
||||
<a href="qwidget.html#setAcceptDrops">setAcceptDrops(TRUE)</a> in the class
|
||||
constructor.
|
||||
If you passed something other than <tt>this</tt>,
|
||||
your code will not work. A common case is passing
|
||||
the
|
||||
<a href="qscrollview.html#viewport">viewport()</a> of a <a href="qlistview.html">QListView</a>,
|
||||
in which case,
|
||||
override the
|
||||
<a href="qscrollview.html#contentsDragMoveEvent">contentsDragMoveEvent()</a>,
|
||||
etc.
|
||||
functions rather than QListView's dragMoveEvent() etc. For other
|
||||
cases, you will need to use an event filter to act on the drag/drop events
|
||||
of another widget (as is the usual way to intercept foreign events).
|
||||
<p> <h3><a name="QScrollView">QScrollView</a></h3>
|
||||
<p> The parameters in the signal
|
||||
<a href="qscrollview.html#contentsMoving">contentsMoving(int,int)</a>
|
||||
are now positive rather than negative values, coinciding with
|
||||
<a href="qscrollview.html#setContentsPos">setContentsPos()</a>. Search for
|
||||
connections you make to this signal, and either change the slot they are
|
||||
connected to such that it also expects positive rather than negative
|
||||
values, or introduce an intermediate slot and signal that negates them.
|
||||
<p> If you used drag and drop with <a href="qscrollview.html">QScrollView</a>, you may experience the problem
|
||||
described for <a href="#QDropSite">QDropSite</a>.
|
||||
<p> <h3><a name="QTextStream">QTextStream</a></h3>
|
||||
<p> <p>
|
||||
<pre> operator<<(QTextStream&, QChar&)</pre>
|
||||
does not skip whitespace.
|
||||
<pre> operator<<(QTextStream&, char&)</pre>
|
||||
does,
|
||||
as was the case with Qt 1.x. This is for backward compatibility.
|
||||
<p> <h3><a name="QUriDrag">QUriDrag</a></h3>
|
||||
<p> The class QUrlDrag is renamed to <a href="quridrag.html">QUriDrag</a>, and the API has been
|
||||
broadened to include additional conversion routines, including
|
||||
conversions to Unicode filenames (see the class documentation
|
||||
for details). Note that in Qt 1.x
|
||||
the QUrlDrag class used the non-standard MIME type "url/url",
|
||||
while QUriDrag uses the standardized "text/uri-list" type. Other
|
||||
identifiers affected by the Url to Uri change are
|
||||
QUrlDrag::setUrls() and QUrlDrag::urlToLocalFile().
|
||||
<p> <h3><a name="QPainter">QPainter</a></h3>
|
||||
<p> <p> The GrayText painter flag has been removed. Use
|
||||
<a href="qpainter.html#setPen">setPen( palette().disabled().foreground() )</a>
|
||||
instead.
|
||||
<p> <p> The RasterOp enum
|
||||
(CopyROP,
|
||||
OrROP,
|
||||
XorROP,
|
||||
NotAndROP,
|
||||
EraseROP,
|
||||
NotCopyROP,
|
||||
NotOrROP,
|
||||
NotXorROP,
|
||||
AndROP, NotEraseROP,
|
||||
NotROP,
|

ClearROP,
|

SetROP,
|
||||
NopROP,
|
||||
AndNotROP,
|
||||
OrNotROP,
|
||||
NandROP,
|
||||
NorROP, LastROP)
|
||||
is now part of the Qt namespace class, so if you
|
||||
use it outside a member function, you'll need to prefix with Qt::.
|
||||
<p> <h3><a name="QPicture">QPicture</a></h3>
|
||||
<p> <p>The binary storage format of <a href="qpicture.html">QPicture</a> is changed, but the Qt 2.x
|
||||
QPicture class can both read and write Qt 1.x format QPictures. No
|
||||
special handling is required for reading; QPicture will automatically
|
||||
detect the version number. In order to write a Qt 1.x format QPicture,
|
||||
set the formatVersion parameter to 1 in the QPicture constructor.
|
||||
<p> <p>For writing Qt 1.x format QPictures, the compatibility issues of <a
|
||||
href="#QDataStream">QDataStream</a> applies.
|
||||
<p> <p>It is safe to try to read a QPicture file generated with Qt 2.x
|
||||
(without formatVersion set to 1) with a program compiled with Qt
|
||||
1.x. The program will not crash, it will just issue the warning
|
||||
"QPicture::play: Incompatible version 2.x" and refuse to load the
|
||||
picture.
|
||||
<p> <h3><a name="QPoint">QPoint, <a href="qpointarray.html">QPointArray</a>, <a href="qsize.html">QSize</a> and <a href="qrect.html">QRect</a></a></h3>
|
||||
<p> <p>The basic coordinate datatype in these classes, QCOORD, is now 32
|
||||
bit (int) instead of a 16 bit (short). The const values QCOORD_MIN and
|
||||
QCOORD_MAX have changed accordingly.
|
||||
<p> <p>QPointArray is now actually, not only seemingly, a QArray of <a href="qpoint.html">QPoint</a>
|
||||
objects. The semi-internal workaround classes QPointData and QPointVal
|
||||
are removed since they are no longer needed; QPoint is used directly
|
||||
instead. The function <pre> QPointArray::shortPoints()</pre>
|
||||
|
||||
provides the point array converted to short (16bit) coordinates for
|
||||
use with external functions that demand that format.
|
||||
<p> <h3><a name="QImage">QImage</a></h3>
|
||||
<p> <a href="qimage.html">QImage</a> uses QRgb for the colors - see <a href="#QRgb">the changes to that</a>.
|
||||
<p> <h3><a name="QPixmap">QPixmap</a></h3>
|
||||
<p> <pre> QPixmap::convertToImage()</pre>
|
||||
with bitmaps now guarantees that color0 pixels
|
||||
become color(0) in the resulting QImage. If you worked around the lack of
|
||||
this, you may be able to simplify your code. If you made assumptions
|
||||
about the previous undefined behavior, the symptom will be inverted
|
||||
bitmaps (eg. "inside-out" masks).
|
||||
<p> <p>
|
||||
<pre> QPixmap::optimize(TRUE)</pre>
|
||||
|
||||
is replaced by
|
||||
<pre> QPixmap::setOptimization(QPixmap::NormalOptim)</pre>
|
||||
|
||||
or
|
||||
<pre> QPixmap::setOptimization(QPixmap::BestOptim)</pre>
|
||||
|
||||
- see the documentation
|
||||
to choose which is best for your application. NormalOptim is most like
|
||||
the Qt 1.x "TRUE" optimization.
|
||||
<p> <h3><a name="QMenuData">QMenuData / <a href="qpopupmenu.html">QPopupMenu</a></a></h3>
|
||||
<p> In Qt 1.x, new menu items were assigned either an application-wide
|
||||
unique identifier or an identifier equal to the index of the item, depending on the
|
||||
<a href="qmenudata.html#insertItem">insertItem(...)</a> function used.
|
||||
In Qt 2.x this confusing
|
||||
situation has been cleaned up: generated identifiers are always
|
||||
unique across the entire application.
|
||||
<p> If your code depends on generated ids
|
||||
being equal to the item's index, a quick fix is to use
|
||||
<pre> QMenuData::indexOf(int id)</pre>
|
||||
|
||||
in the handling function instead. You may alternatively pass
|
||||
<pre> QMenuData::count()</pre>
|
||||
|
||||
as identifier when you insert the items.
|
||||
<p> Furthermore, QPopupMenus can (and should!) be created with a parent
|
||||
widget now, for example the main window that is used to display the
|
||||
popup. This way, the popup will automatically be destroyed together
|
||||
with its main window. Otherwise you'll have to take care of the
|
||||
ownership manually.
|
||||
<p> QPopupMenus are also reusable in 2.x. They may occur in different
|
||||
locations within one menu structure or be used as both a menubar
|
||||
drop-down and as a context popup-menu. This should make it possible to
|
||||
significantly simplify many applications.
|
||||
<p> Last but not least, <a href="qpopupmenu.html">QPopupMenu</a> no longer inherits QTableView. Instead,
|
||||
it directly inherits <a href="qframe.html">QFrame</a>.
|
||||
<p> <h3><a name="QValidator">QValidator (<a href="qlineedit.html">QLineEdit</a>, <a href="qcombobox.html">QComboBox</a>, <a href="qspinbox.html">QSpinBox</a>) </a></h3>
|
||||
<p> <pre> QValidator::validate(...)</pre>
|
||||
|
||||
and
|
||||
<pre> QValidator::fixup( <a href="qstring.html">QString</a> & )</pre>
|
||||
|
||||
are now const
|
||||
functions. If your subclass reimplements validate() as a
|
||||
non-const function,
|
||||
you will get a compile error (validate was pure virtual).
|
||||
<p> In QLineEdit, QComboBox, and QSpinBox,
|
||||
setValidator(...) now takes a const pointer to a <a href="qvalidator.html">QValidator</a>, and
|
||||
validator() returns a const pointer. This change highlights the fact
|
||||
that the widgets do not take the ownership of the validator (a validator is
|
||||
a <a href="qobject.html">QObject</a> on its own, with its own parent - you can easily set the same validator
|
||||
object on many different widgets), so changing the state of
|
||||
such an object or deleting it is very likely a bug.
|
||||
<p> <h3><a name="QFile">QFile, <a href="qfileinfo.html">QFileInfo</a>, <a href="qdir.html">QDir</a></a></h3>
|
||||
<p> File and directory names are now always Unicode strings (ie. <a href="qstring.html">QString</a>). If you used QString
|
||||
in the past for the simplicity it offers, you'll probably have little consequence. However,
|
||||
if you pass filenames to system functions rather than using Qt functions (eg. if you use the
|
||||
Unix <tt>unlink()</tt> function rather than <tt>QFile::remove()</tt>, your code will probably
|
||||
only work for Latin1 locales (eg. Western Europe, the U.S.). To ensure your code will support
|
||||
filenames in other locales, either use the Qt functions, or convert the filenames via
|
||||
<pre> QFile::encodeFilename()</pre>
|
||||
and <pre> QFile::decodeFilename()</pre>
|
||||
- but do it
|
||||
<em>just</em> as you call the system function - code that mixes encoded and unencoded filenames
|
||||
is very error prone. See the comments in QString, such as regarding QT_NO_ASCII_CAST that
|
||||
can help find potential problems.
|
||||
<p> <h3><a name="QFontMetrics">QFontMetrics</a></h3>
|
||||
<p> boundingRect(char) is replaced by
|
||||
boundingRect(<a href="qchar.html">QChar</a>), but since
|
||||
char auto-converts to QChar, you're not likely to run into problems
|
||||
with this.
|
||||
<p> <h3><a name="QWindow">QWindow</a></h3>
|
||||
<p> This class (which was just <a href="qwidget.html">QWidget</a> under a different name) has been
|
||||
removed. If you used it, do a global search-and-replace of the word
|
||||
"QWindow" with "QWidget".
|
||||
<p> <h3><a name="QEvent">QEvent</a></h3>
|
||||
<p> <p> The global #define macros in qevent.h have been replaced by an
|
||||
enum in <a href="qevent.html">QEvent</a>. Use e.g. QEvent::Paint instead of Event_Paint. Same
|
||||
for all of:
|
||||
Event_None,
|
||||
Event_Timer,
|
||||
Event_MouseButtonPress,
|
||||
Event_MouseButtonRelease,
|
||||
Event_MouseButtonDblClick,
|
||||
Event_MouseMove,
|
||||
Event_KeyPress,
|
||||
Event_KeyRelease,
|
||||
Event_FocusIn,
|
||||
Event_FocusOut,
|
||||
Event_Enter,
|
||||
Event_Leave,
|
||||
Event_Paint,
|
||||
Event_Move,
|
||||
Event_Resize,
|
||||
Event_Create,
|
||||
Event_Destroy,
|
||||
Event_Show,
|
||||
Event_Hide,
|
||||
Event_Close,
|
||||
Event_Quit,
|
||||
Event_Accel,
|
||||
Event_Clipboard,
|
||||
Event_SockAct,
|
||||
Event_DragEnter,
|
||||
Event_DragMove,
|
||||
Event_DragLeave,
|
||||
Event_Drop,
|
||||
Event_DragResponse,
|
||||
Event_ChildInserted,
|
||||
Event_ChildRemoved,
|
||||
Event_LayoutHint,
|
||||
Event_ActivateControl,
|
||||
Event_DeactivateControl,
|
||||
and
|
||||
Event_User.
|
||||
<p> <p> The Q_*_EVENT macros in qevent.h have been deleted. Use an
|
||||
explicit cast instead. The macros were:
|
||||
Q_TIMER_EVENT,
|
||||
Q_MOUSE_EVENT,
|
||||
Q_KEY_EVENT,
|
||||
Q_FOCUS_EVENT,
|
||||
Q_PAINT_EVENT,
|
||||
Q_MOVE_EVENT,
|
||||
Q_RESIZE_EVENT,
|
||||
Q_CLOSE_EVENT,
|
||||
Q_SHOW_EVENT,
|
||||
Q_HIDE_EVENT,
|
||||
and
|
||||
Q_CUSTOM_EVENT.
|
||||
<p> <p> QChildEvents are now sent for all QObjects, not just QWidgets.
|
||||
You may need to add extra checking if you use a <a href="qchildevent.html">QChildEvent</a> without
|
||||
much testing of its values.
|
||||
<p> <h3>All the removed functions</h3>
|
||||
<p> All <a href="removed20.html">these functions</a> have been removed in
|
||||
Qt 2.x. Most are simply cases where "const char*" has changed to
|
||||
"const <a href="qstring.html">QString</a>&", or when an enumeration type has moved into the Qt::
|
||||
namespace (which, technically, is a new name, but your code will
|
||||
compile just the same anyway). This list is provided for completeness.

|

qt20fix \- Helps clean namespace when porting an app from Qt1 to Qt2

.SH "DESCRIPTION"
|
||||
.LP
|
||||
Qt 2.x is namespace\-clean, unlike 1.x. Qt now uses very
|
||||
few global identifiers. Identifiers like red, blue,
|
||||
LeftButton, AlignRight, Key_Up, Key_Down, NoBrush etc.
|
||||
are now part of a special class Qt (defined in
|
||||
qnamespace.h), which is inherited by most Qt classes.
|
||||
Member functions of classes that inherit from QWidget,
|
||||
etc. are totally unaffected, but code that is not in
|
||||
functions of classes inherited from Qt, you must qualify
|
||||
these identifiers like this: Qt::red, Qt::LeftButton,
|
||||
Qt::AlignRight, etc.
|
||||
|
||||
The qt/bin/qt20fix script helps to fix the code that
|
||||
needs adaption, though most code does not need changing.
|
||||
|
||||
Compiling with \-DQT1COMPATIBILITY will help you get going
|
||||
with Qt 2.x \- it allows all the old "dirty namespace"
|
||||
identifiers from Qt 1.x to continue working. Without it,
|
||||
you'll get compile errors that can easily be fixed by
|
||||
searching this page for the clean identifiers.
