\title Porting to Qt 2.x
|
|
|
|
<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>
|
|
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.
|
|
|
|
|
|
To port code using Qt 1.x to use Qt 2.x:
|
|
|
|
<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>
|
|
|
|
|
|
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!

<h3><a name="Namespace">Namespace</a></h3>
|
|
|
|
<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 ntqnamespace.h),
|
|
which is inherited by
|
|
most Qt classes. Member functions of classes that inherit from QWidget,
|
|
etc. are totally unaffected, but code that is
|
|
<em>not</em> in functions of classes inherited from <code>Qt</code>,
|
|
you must qualify these identifiers like this: <code>Qt::red,
|
|
Qt::LeftButton, Qt::AlignRight</code>, etc.
|
|
|
|
<p>The <code>qt/bin/qt20fix</code> 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.
|
|
|
|
<h3><a name="DefaultParent">No Default 0 Parent Widget</a></h3>
|
|
|
|
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.
|
|
|
|
Note also that programs no longer need (or should) use 0 parent just
|
|
to indicate that a widget should be top-level. See
|
|
\code QWidget::isTopLevel() \endcode for details. See also the notes about
|
|
<a href="#QMenuData">QPopupMenu</a> and <a href="#QDialog">QDialog</a>
|
|
below.
|
|
|
|
<h3><a name="Virtual">Virtual Functions</a></h3>
|
|
|
|
<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.
|
|
|
|
<!-- warwick can check for additions to this with his qt-2-report -->
|
|
<ul>
|
|
<li>\code QWidget::setStyle(GUIStyle)\endcode
|
|
<li>\code QListView::addColumn(const char *, int)\endcode
|
|
<li>\code QListView::setColumnText(int, const char *)\endcode
|
|
<li>\code QListViewItem::setText(int, const char *)\endcode
|
|
<li>\code QMultiLineEdit::insertLine(const char *, int)\endcode
|
|
<li>\code QMultiLineEdit::insertAt(const char *, int, int, bool)\endcode
|
|
<li>\code QSpinBox::setPrefix(const char *)\endcode
|
|
<li>\code QSpinBox::setSuffix(const char *)\endcode
|
|
<li>\code QToolButton::setTextLabel(const char *, bool)\endcode
|
|
<li>\code QDoubleValidator::validate(QString &, int &)\endcode
|
|
<li>\code QIntValidator::validate(QString &, int &)\endcode
|
|
<li>\code QValidator::fixup(QString &)\endcode
|
|
<li>\code QSlider::paintSlider(QPainter *, const QRect &)\endcode
|
|
</ul>
|
|
|
|
This is one class of changes that are
|
|
not detected by the compiler,
|
|
so you should mechanically search for each of
|
|
these function names in your header files, eg.
|
|
|
|
\code
|
|
egrep -w 'setStyle|addColumn|setColumnText|setText...' *.h
|
|
\endcode
|
|
|
|
Of course, you'll get a few false positives (eg. if you have a setText
|
|
function that is not in a subclass of QListViewItem).
|
|
|
|
|
|
<h3><a name="Collection">Collection classes</a></h3>
|
|
|
|
<p> The collection classes include generic
|
|
classes such as QGDict, QGList, and
|
|
the subclasses such as QDict and QList.
|
|
|
|
<p> The macro-based Qt collection classes are obsolete; use the
|
|
template-based classes instead. Simply remove includes of ntqgeneric.h and
|
|
replace e.g. Q_DECLARE(QCache,QPixmap) with QCache<QPixmap>.
|
|
|
|
<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.
|
|
|
|
<p> The GCF global typedef is removed (it was not used in Qt).
|
|
|
|
|
|
|
|
<h3><a name="DebugVsRelease">Debug vs. Release</a></h3>
|
|
|
|
<p>The Q_ASSERT macro is now a null expression if the QT_CHECK_STATE flag
|
|
is not set (i.e. if the QT_NO_CHECK flag is defined).
|
|
|
|
<p>The debug() function now outputs nothing if Qt was compiled with
|
|
the QT_NO_DEBUG macro defined.
|
|
|
|
|
|
<h3><a name="QString">QString</a></h3>
|
|
|
|
QString 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 QCString 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>
|
|
To take full advantage of the new Internationalization
|
|
functionality in Qt 2.x, the following steps are required:
|
|
|
|
<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).
|
|
|
|
If you find that you are mixing usage of QCString, QString,
|
|
and QByteArray, 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 QString.
|
|
</p>
|
|
|
|
<li> Put a breakpoint in \code QString::latin1()\endcode
|
|
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 \link i18n.html Internationalization page\endlink
|
|
for information about the full process of internationalizing
|
|
your software.
|
|
</ul>
|
|
|
|
<p>
|
|
Points to note about the new QString are:
|
|
|
|
<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.
|
|
|
|
<dt><b>Automatic-expanding</b></dt>
|
|
<dd>
|
|
A big advantage of the new QString is that it automatically expands
|
|
when you write to an indexed position.
|
|
|
|
<dt><b>QChar and QCharRef</b></dt>
|
|
<dd>
|
|
QChar 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 implicit sharing 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).
|
|
|
|
<dt><b>Use QString</b></dt>
|
|
<dd>
|
|
Try to always use QString. If you <em>must</em>, use QCString which is the
|
|
old implementation from Qt 1.x.
|
|
|
|
<dt><b>Unicode vs. ASCII</b></dt>
|
|
<dd>
|
|
Every conversion to and from ASCII is wasted time, so try to use QString
|
|
as much as possible rather than const char*. This also ensures you have
|
|
full 16-bit support.
|
|
|
|
<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.
|
|
|
|
<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.
|
|
|
|
<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) )
|
|
|
|
<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 QString::left(int) or QString::fromLatin1( const char*,
|
|
int ) -- in both cases the int parameter signifies the number of characters.
|
|
|
|
<dt><b>QString(int) is private</b></dt>
|
|
<dd>
|
|
The QString 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 \code QString::sprintf()\endcode. 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 QString::null, though note that
|
|
the default constructor, QString(), creates a null string too.
|
|
Assignment of 0 to a QString 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>
|
|
Also see <a href="#QStrList">QStrList</a>.
|
|
|
|
<dt><b>Signals and Slots</b></dt>
|
|
<dd>
|
|
Many signal/slots have changed from const char* to QString. You will
|
|
get run-time errors when you try to \code QObject::connect()\endcode
|
|
to the old
|
|
signals and slots, usually with a message indicating the const QString&
|
|
replacement signal/slot.
|
|
|
|
<dt><b>Optimize with Q2HELPER</b></dt>
|
|
<dd>
|
|
In qt/src/tools/qstring.cpp there is a Q2HELPER - define it for some
|
|
extra debugging/optimizing features (don't leave it it - it kills performance).
|
|
You'll get an extra function, qt_qstring_stats(), which will print a
|
|
summary of how much your application is doing Unicode and ASCII
|
|
back-and-forth conversions.
|
|
|
|
<dt><b>QString::detach() is obsolete and removed</b></dt>
|
|
<dd>
|
|
Since QString is now always shared, this function does nothing.
|
|
Remove calls to QString::detach().
|
|
|
|
<dt><b>QString::resize(int size) is obsolete and removed</b></dt>
|
|
<dd>
|
|
Code using this to truncate a string should use
|
|
\link QString::truncate() truncate(size-1)\endlink.
|
|
Code using qstr.resize(0) should use qstr = QString::null.
|
|
Code calling resize(n) prior to using
|
|
\link QString::operator[]() operator[]\endlink up to n just remove
|
|
the resize(n) completely.
|
|
|
|
<dt><b>QString::size() is obsolete and removed</b></dt>
|
|
<dd>
|
|
Calls to this function must be replaced by
|
|
\link QString::length() length()\endlink+1.
|
|
|
|
<dt><b>QString::setStr(const char*) is removed</b></dt>
|
|
<dd>Try to understand why you were using this.
|
|
If you just meant assignment, use that. Otherwise,
|
|
you are probably using QString as an array of bytes, in which case use
|
|
QByteArray or QCString instead.
|
|
|
|
<dt><b>QString is not an array of bytes</b></dt>
|
|
<dd>
|
|
Code that uses QString as an array of bytes should use QByteArray
|
|
or a char[], <em>then</em> convert that to a QString if needed.
|
|
|
|
<dt><b>"string = 0"</b></dt>
|
|
<dd>
|
|
Assigning 0 to a QString should be assigning the null string,
|
|
ie. string = QString::null.
|
|
|
|
<dt><b>System functions</b></dt>
|
|
<dd>
|
|
You may find yourself needing latin1() for passing to the operating system

or other libraries, and be tempted to use QCString to save the conversion,
|
|
but you are better off using Unicode throughout, then when the operating
|
|
system supports Unicode, you'll be prepared. Some Unix operating systems
|
|
are now beginning to have basic Unicode support, and Qt will be tracking
|
|
these improvements as they become more widespread.

toShort() returns 0 (and sets *ok to false) on error.

toUInt() now works for big valid unsigned integers.

|
|
When converting "const char*" usage to QString in order to make your
|
|
application fully Unicode-aware, use QString::null for the null value
|
|
where you would have used 0 with char pointers.
|
|
|
|
<dt><b>QString is not null terminated</b></dt>
|

<dd>
|
|
This means that inserting a 0-character
|
|
in the middle of the string does <em>not</em> change the length(). ie.
|
|
\code
|
|
QString s = "fred";
|
|
s[1] = '\0';
|
|
// s.length() == 4
|
|
// s == "f\0ed"
|
|
// s.latin1() == "f"
|
|
s[1] = 'r';
|
|
// s == "fred"
|
|
// s.latin1() == "fred"
|
|
\endcode
|
|
Especially look out for this type of code:
|
|
\code
|
|
QString s(2);
|
|
s[0] = '?';
|
|
s[1] = 0;
|
|
\endcode
|
|
This creates a string 2 characters long.
|
|
To find these problems while converting, you might like to
|
|
add Q_ASSERT(strlen(d->ascii)==d->len) inside
|
|
\code QString::latin1()\endcode.
|
|
|
|
<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 QString, it is less efficient than using QString throughout.
|
|
For example, when using:
|
|
\code
|
|
QLabel::setText( const QString& )
|
|
\endcode
|
|
if you use string, like this:
|
|
\code
|
|
void myclass::dostuffwithtext( const string& str )
|
|
{
|
|
mylabel.setText( QString(str.c_str()) );
|
|
}
|
|
\endcode
|
|
that will create a (ASCII only) copy of str, stored in mylabel.
|
|
But this:
|
|
\code
|
|
void myclass::dostuffwithtext( const QString& str )
|
|
{
|
|
mylabel.setText( str );
|
|
}
|
|
\endcode
|
|
will make an implicitly shared reference to str in the QLabel - no copying
|
|
at all. This function might be 10 nested function calls away from something
|
|
like this:
|
|
\code
|
|
void toplevelclass::initializationstuff()
|
|
{
|
|
doStuff( tr("Okay") );
|
|
}
|
|
\endcode
|
|
At this point, in Qt 2.x, the tr() does a very fast dictionary lookup
|
|
through memory-mapped message files, returning some Unicode QString 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.

In members of classes that inherit the Qt namespace-class (eg. QWidget

|
See also the <a href="#QRgb">QRgb</a> section below.
|
|
|
|
<h3><a name="QRgb">QRgb</a></h3>
|
|
|
|
In QRgb (a typedef of long), the order of the RGB channels has changed to
|
|
be in the more efficient order (for typical contemporary hardware). If your
|
|
code made assumptions about the order, you will get blue where you expect
|
|
red and vice versa (you'll not notice the problem if you use shades of
|
|
gray, green, or magenta). You should port your code to use the
|
|
creator function tqRgb(int r,int g,int b) and the
|
|
access functions tqRed(QRgb), tqBlue(QRgb), and tqGreen(QRgb).
|
|
If you are using the alpha channel, it hasn't moved, but you should use
|
|
the functions tqRgba(int,int,int,int) and tqAlpha(QRgb). Note also that
|
|
QColor::pixel() 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 QColor::rgb() if you want a QRgb.

<h3><a name="QDataStream">QDataStream</a></h3>

|
|
|
<p>The QDatastream serialization format of most Qt classes is changed
|
|
in Qt 2.x. Use \code QDataStream::setVersion( 1 )\endcode to get a
|
|
datastream object that can read and write Qt 1.x format data streams.
|
|
|
|
<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 \code
|
|
QString::latin1().\endcode
|
|
<li><a href="#QPoint">QPoint & al.</a>: Coordinates will be

<h3><a name="QWidget">QWidget</a></h3>
|
|
|
|
<h4>QWidget::recreate()</h4>
|
|
<p>
|
|
This function is now called \link QWidget::reparent() reparent()\endlink.
|
|
|
|
<h4>QWidget::setAcceptFocus(bool)</h4>
|
|
<p>
|
|
This function is removed.
|
|
Calls like QWidget::setAcceptFocus(TRUE) should be replaced by
|
|
\code QWidget::setFocusPolicy(StrongFocus)\endcode, and
|
|
calls like QWidget::setAcceptFocus(FALSE) should be replaced by
|
|
\code QWidget::setFocusPolicy(NoFocus)\endcode.
|
|
Additional policies are TabFocus and ClickFocus.
|
|
|
|
|
|
<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
|
|
QPainter::setClipRegion() superfluous. Apart from the improved
|
|
consistency, the change is likely to reduce flicker and to make Qt
|
|
event slightly faster.
|
|
|
|
<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 QIODevice,
|
|
check every occurrence of the string "index" in the implementation, since
|
|
a compiler will not always catch cases like \code(uint)index\endcode
|
|
that need to be changed.
|
|
|
|
<h3><a name="QLabel">QLabel</a></h3>
|
|
|
|
<h4>\code QLabel::setMargin()\endcode</h4>
|
|
<p>
|
|
\code QLabel::setMargin()\endcode and\code QLabel::margin()\endcode
|
|
have been renamed to \code QLabel::setIndent()\endcode and
|
|
\code QLabel::indent()\endcode, respectively. This was done to avoid
|
|
collision with QFrame::setMargin(), which is now virtual.
|
|
|
|
<h4>\code QLabel::setMovie()\endcode</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.
|
|
|
|
|
|
<h3><a name="QDialog">QDialog</a></h3>
|
|
|
|
<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>
|
|
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
|
|
QDialog::QDialog() conditional on parent not being 0.
|
|
|
|
|
|
<h3><a name="QStrList">QStrList</a></h3>
|
|
|
|
Many methods that took a QStrList can now instead take a QStringList,
|
|
which is a real list of QString values.
|
|
|
|
To use QStringList rather than QStrList, change loops that look like this:
|
|
\code
|
|
QStrList list = ...;
|
|
const char* s;
|
|
for ( s = list.first(); s; s = list.next() ) {
|
|
process(s);
|
|
}
|
|
\endcode
|
|
to be like this:
|
|
\code
|
|
QStringList list = ...;
|
|
QStringList::ConstIterator i;
|
|
for ( i = list.begin(); i != list.end(); ++i ) {
|
|
process(*i);
|
|
}
|
|
\endcode
|
|
|
|
In general, the QStrList functions are less efficient, building a temporary QStringList.
|
|
|
|
The following functions now use QStringList rather than QStrList
|
|
for return types/parameters.
|
|
|
|
<ul>
|
|
<li><tt>void QFileDialog::setFilters(const QStrList&)</tt>
|
|
becomes <tt>void QFileDialog::setFilters(const QStringList&)</tt>
|
|
<li><tt>QStrList QFileDialog::getOpenFileNames(...)</tt>
|
|
becomes <tt>QStringList QFileDialog::getOpenFileNames(...)</tt>
|
|
<li><tt>bool QUrlDrag::decodeLocalFiles(QMimeSource*, QStrList&)</tt>
|
|
becomes <tt>bool QUriDrag::decodeLocalFiles(QMimeSource*, QStringList&)</tt>
|
|
<li><tt>const QStrList *QDir::entryList(...) const</tt>
|
|
becomes <tt>QStringList QDir::entryList(...) const</tt>
|
|
(note that the return type is no longer a pointer). You may also
|
|
choose to use encodedEntryList().
|
|
</ul>
|
|
|
|
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>
|
|
|
|
The rarely used static function <tt>void
|
|
QFont::listSubstitutions(QStrList*)</tt> is replaced by <tt>QStringList
|
|
QFont::substitutions()</tt>.
|
|
|
|
|
|
<h3><a name="QLayout">QLayout</a></h3>
|
|
|
|
<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
|
|
\link QWidget::sizeHint() sizeHint()\endlink.
|
|
|
|
<p> The default implementation of QWidget::sizeHint() will no longer
|
|
return just an invalid size; if the widget has a layout, it will return
|
|
the layout's preferred size.
|
|
|
|
<p> The special maximum MaximumHeight/Width is now QWIDGETSIZE_MAX,
|
|
not QCOORD_MAX.
|
|
|
|
<p> \link QBoxLayout::addWidget() QBoxLayout::addWidget()\endlink
|
|
now interprets the \e alignment 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> The class QGManager is removed. Subclasses of QLayout need to be rewritten
|
|
to use the new, much simpler \link QLayout QLayout API\endlink.
|
|
|
|
<p> For typical layouts, all use of
|
|
\link QWidget::setMinimumSize() setMinimumSize()\endlink
|
|
and
|
|
\link QWidget::setFixedSize() setFixedSize()\endlink
|
|
can be removed.
|
|
\link QLayout::activate() activate()\endlink is no longer necessary.
|
|
|
|
<p>
|
|
You might like to look at the QGrid, QVBox, and QHBox widgets - they offer
|
|
a simple way to build nested widget structures.
|
|

|
|
<h3><a name="QListView">QListView</a></h3>
|
|
|
|
<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 QScrollView 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(),
|
|
QListView::mouseDoubleClickEvent(), QListView::mouseMoveEvent(), or
|
|
QListView::mouseReleaseEvent() you must instead override
|
|
viewportMousePressEvent(),
|
|
viewportMouseDoubleClickEvent(), viewportMouseMoveEvent(), or
|
|
viewportMouseReleaseEvent() respectively. New code will usually override
|
|
contentsMousePressEvent() etc.
|
|
|
|
<p>The signal QListView::selectionChanged(QListViewItem *) can now be
|
|
emitted with a null pointer as parameter. Programs that use the
|
|
argument without checking for 0, may crash.
|
|
|
|
<h3><a name="QMultiLineEdit">QMultiLineEdit</a></h3>
|
|
|
|
<p>
|
|
The protected function
|
|
\code QMultiLineEdit::textWidth(QString*)\endcode
|
|
changed to
|
|
\code QMultiLineEdit::textWidth(const QString&)\endcode.
|
|
This is unlikely to be a problem, and you'll get a compile error
|
|
if you called it.
|
|
|
|
|
|
<h3><a name="QClipboard">QClipboard</a></h3>
|
|
|
|
<p>
|
|
\code QClipboard::pixmap()\endcode now returns a QPixmap, not a QPixmap*.
|
|
The pixmap
|
|
will be \link QPixmap::isNull() null\endlink if no pixmap is on the
|
|
clipboard. QClipboard 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).
|
|
|
|
|
|
<h3><a name="QDropSite">QDropSite</a></h3>
|
|
|
|
<P>
|
|
QDropSite is obsolete. If you simply passed <tt>this</tt>, just remove
|
|
the inheritance of QDropSite and call
|
|
\link QWidget::setAcceptDrops() setAcceptDrops(TRUE)\endlink in the class
|
|
constructor.
|
|
If you passed something other than <tt>this</tt>,
|
|
your code will not work. A common case is passing
|
|
the
|
|
\link QScrollView::viewport() viewport()\endlink of a QListView,
|
|
in which case,
|
|
override the
|
|
\link QScrollView::contentsDragMoveEvent() contentsDragMoveEvent()\endlink,
|
|
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).
|
|
|
|
|
|
<h3><a name="QScrollView">QScrollView</a></h3>
|
|
|
|
The parameters in the signal
|
|
\link QScrollView::contentsMoving() contentsMoving(int,int)\endlink
|
|
are now positive rather than negative values, coinciding with
|
|
\link QScrollView::setContentsPos() setContentsPos()\endlink. 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.
|
|
|
|
If you used drag and drop with QScrollView, you may experience the problem
|
|
described for <a href="#QDropSite">QDropSite</a>.

<h3><a name="QUriDrag">QUriDrag</a></h3>
|
|
|
|
The class QUrlDrag is renamed to QUriDrag, 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().
|
|
|
|
<h3><a name="QPainter">QPainter</a></h3>
|
|
|

<h3><a name="QPicture">QPicture</a></h3>
|
|
|
|
<p>The binary storage format of QPicture 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>For writing Qt 1.x format QPictures, the compatibility issues of <a
|
|
href="#QDataStream">QDataStream</a> applies.
|
|
|
|
<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
|

<h3><a name="QPoint">QPoint, QPointArray, QSize and QRect</a></h3>
|
|
|
|
<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>QPointArray is now actually, not only seemingly, a QArray of QPoint
|
|
objects. The semi-internal workaround classes QPointData and QPointVal
|
|
are removed since they are no longer needed; QPoint is used directly
|
|
instead. The function \code QPointArray::shortPoints()\endcode
|
|
provides the point array converted to short (16bit) coordinates for
|
|
use with external functions that demand that format.

<h3><a name="QPixmap">QPixmap</a></h3>
|
|

\code QPixmap::convertToImage()\endcode with bitmaps now guarantees that color0 pixels

this, you may be able to simplify your code. If you made assumptions

bitmaps (eg. "inside-out" masks).

|
|
\code QPixmap::setOptimization(QPixmap::BestOptim)\endcode
|
|
- see the documentation
|
|
to choose which is best for your application. NormalOptim is most like
|
|
the Qt 1.x "TRUE" optimization.
|
|
|
|
|
|
<h3><a name="QMenuData">QMenuData / QPopupMenu</a></h3>
|
|
|
|
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
|
|
\link QMenuData::insertItem() insertItem(...)\endlink function used.
|
|
In Qt 2.x this confusing
|
|
situation has been cleaned up: generated identifiers are always
|
|
unique across the entire application.
|
|
|
|
If your code depends on generated ids
|
|
being equal to the item's index, a tquick fix is to use
|
|
\code QMenuData::indexOf(int id)\endcode
|
|
in the handling function instead. You may alternatively pass
|
|
\code QMenuData::count()\endcode
|
|
as identifier when you insert the items.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
Last but not least, QPopupMenu no longer inherits QTableView. Instead,
|
|
it directly inherits QFrame.
|
|
|
|
<h3><a name="QValidator">QValidator (QLineEdit, QComboBox, QSpinBox) </a></h3>
|
|
|
|
\code QValidator::validate(...)\endcode
|
|
and
|
|
\code QValidator::fixup( QString & )\endcode
|
|
are now const
|
|
functions. If your subclass reimplements validate() as a
|
|
non-const function,
|
|
you will get a compile error (validate was pure virtual).
|
|
|
|
In QLineEdit, QComboBox, and QSpinBox,
|
|
setValidator(...) now takes a const pointer to a QValidator, 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 QObject 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.
|
|
|
|
|
|
<h3><a name="QFile">QFile, QFileInfo, QDir</a></h3>
|
|
|
|
File and directory names are now always Unicode strings (ie. QString). 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
|
|
\code QFile::encodeFilename()\endcode and \code QFile::decodeFilename()\endcode - but do it
|
|
\e just 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.
|
|
|
|
|
|
<h3><a name="QFontMetrics">QFontMetrics</a></h3>
|
|
|
|
boundingRect(char) is replaced by
|
|
boundingRect(QChar), but since
|
|
char auto-converts to QChar, you're not likely to run into problems
|
|
with this.
|
|
|
|
|
|
<h3><a name="QWindow">QWindow</a></h3>
|
|
|
|
This class (which was just QWidget under a different name) has been
|
|
removed. If you used it, do a global search-and-replace of the word
|
|
"QWindow" with "QWidget".
|
|
|
|
|
|
<h3><a name="QEvent">QEvent</a></h3>
|
|
|
|
<p> The global #define macros in ntqevent.h have been replaced by an
|
|
enum in QEvent. 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> The Q_*_EVENT macros in ntqevent.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> QChildEvents are now sent for all QObjects, not just QWidgets.
|
|
You may need to add extra checking if you use a QChildEvent without
|
|
much testing of its values.
|
|
|
|
<h3>All the removed functions</h3>
|
|
|
|
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 QString&", 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.
