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! -</p> - - -<hr> - -<h2 align=center>The Porting Notes</h2> - -<ul> - <li><b><a href="#Namespace">Namespace</a></b> - <li><b><a href="#Virtual">Virtual Functions</a></b> - <li><b><a href="#Collection">Collection classes</a></b> - <li><b><a href="#DefaultParent">No Default 0 Parent Widget</a></b> - <li><b><a href="#DebugVsRelease">Debug vs. Release</a></b> - - <li><b><a href="#QApplication">QApplication</a></b> - <li><b><a href="#QClipboard">QClipboard</a></b> - <li><b><a href="#QColor">QColor</a></b> - <li><b><a href="#QDataStream">QDataStream</a></b> - <li><b><a href="#QDialog">QDialog</a></b> - <li><b><a href="#QDropSite">QDropSite</a></b> - <li><b><a href="#QEvent">QEvent</a></b> - <li><b><a href="#QFile">QFile</a></b> - <li><b><a href="#QFontMetrics">QFontMetrics</a></b> - <li><b><a href="#QIODevice">QIODevice</a></b> - <li><b><a href="#QLabel">QLabel</a></b> - <li><b><a href="#QLayout">QLayout</a></b> - <li><b><a href="#QListView">QListView</a></b> - <li><b><a href="#QMenuData">QMenuData</a></b> - <li><b><a href="#QMenuData">QPopupMenu</a></b> - <li><b><a href="#QMultiLineEdit">QMultiLineEdit</a></b> - <li><b><a href="#QPainter">QPainter</a></b> - <li><b><a href="#QPicture">QPicture</a></b> - <li><b><a href="#QPoint">QPoint, QPointArray, QSize and QRect</a></b> - <li><b><a href="#QPixmap">QPixmap</a></b> - <li><b><a href="#QRgb">QRgb</a></b> - <li><b><a href="#QScrollView">QScrollView</a></b> - <li><b><a href="#QStrList">QStrList</a></b> - <li><b><a href="#QString">QString</a></b> - <li><b><a href="#QTextStream">QTextStream</a></b> - <li><b><a href="#QUriDrag">QUriDrag / QUrlDrag</a></b> - <li><b><a href="#QValidator">QComboBox</a></b> - <li><b><a href="#QValidator">QLineEdit</a></b> - <li><b><a href="#QValidator">QSpinBox</a></b> - <li><b><a href="#QValidator">QValidator</a></b> - <li><b><a href="#QWidget">QWidget</a></b> - <li><b><a href="#QWindow">QWindow</a></b> -</ul> - -<hr> - -<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 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 -<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 qgeneric.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. - -<dt><b>Bugs removed</b></dt> -<dd> -toShort() returns 0 (and sets *ok to false) on error. -toUInt() now works for big valid unsigned integers. -insert() now works into the same string. - -<dt><b>NULL pointers</b></dt> -<dd> -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. - -</dl> - - - -<h3><a name="QApplication">QApplication</a></h3> - -In the function \code QApplication::setColorSpec()\endcode, -PrivateColor and TrueColor are obsolete. Use ManyColor instead. - - -<h3><a name="QColor">QColor</a></h3> - -<p> -All colors -(color0, -color1, -black, -white, -darkGray, -gray, -lightGray, -red, -green, -blue, -cyan, -magenta, -yellow, -darkRed, -darkGreen, -darkBlue, -darkCyan, -darkMagenta, -and -darkYellow) -are in the Qt namespace. -In members of classes that inherit the Qt namespace-class (eg. QWidget -subclasses), you can use the unqualified names as before, but in global -functions (eg. main()), you need to qualify them: Qt::red, Qt::white, etc. -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 qRgb(int r,int g,int b) and the -access functions qRed(QRgb), qBlue(QRgb), and qGreen(QRgb). -If you are using the alpha channel, it hasn't moved, but you should use -the functions qRgba(int,int,int,int) and qAlpha(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 - truncated to the Qt 1.x 16 bit format. - </ul> - -<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="QTextStream">QTextStream</a></h3> - -<p> -\code operator<<(QTextStream&, QChar&)\endcode does not skip whitespace. -\code operator<<(QTextStream&, char&)\endcode does, - as was the case with Qt 1.x. This is for backward compatibility. - -<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> - -<p> The GrayText painter flag has been removed. Use -\link QPainter::setPen() setPen( palette().disabled().foreground() )\endlink -instead. - - -<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::. - - -<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 -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. - - - -<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="QImage">QImage</a></h3> - -QImage uses QRgb for the colors - see <a href="#QRgb">the changes to that</a>. - - -<h3><a name="QPixmap">QPixmap</a></h3> - -\code QPixmap::convertToImage()\endcode 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> -\code QPixmap::optimize(TRUE)\endcode -is replaced by -\code QPixmap::setOptimization(QPixmap::NormalOptim)\endcode -or -\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 quick 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 qevent.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 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> 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).
