Some functions have +been renamed or the arguments have changed. The old versions of these +functions have been obsoleted. A call to an obsoleted function will by +default generate a runtime warning the first time it is called, but it +will be executed correctly. If you really need to ship code fast, you can +turn off the runtime obsolescence warnings by calling +qSuppressObsoleteWarnings(). + +Obsoleted functions will disappear in a future release. To get +compile-time errors for each use of an obsoleted function, compile your +code with -DTEST_OBSOLETE. You should recompile without this option when +you have upgraded your code (otherwise, you may get linking errors). +Note: it is probably not a good idea to compile the Qt library with +-DTEST_OBSOLETE, it may cause problems if you try to link or run +programs that use obsoleted functions. + +For new users: obsoleted functions are no longer documented, in fact they +are not even visible in the documentation. + +*************** Changes that might affect runtime behavior ***************** + +QFileInfo: +---------- + size() returns uint(previousy int), 0 if the size cannot be fetched (was -1). + Use isFile() to check. + + +QPopupMenu +------------ + When a popup menu is a submenu (directly or as a subsub...menu) of a + menu bar(QMenuBar), the menu bar will now always emit the activated() or + highlighted() signal when a submenu emits these signals. This fix might + have undesired effects if you previously have worked around it by + connecting to signals both in menu bar and its submenus. + +*************** Changes that might generate compile errors ***************** +************** when compiling old code ***************** + +QDataStream: +----------- + Serialization of int and uint is no longer supported. Use INT32 and + UINT32 instead. This had to be changed in order to run Qt on 64-bit + architectures. + + +QImage: +------- + 24-bpp pixel format no longer supported, use 32-bpp instead. + + This means that you have to use uint* instead of uchar* when accessing + pixel values. You cannot use the uchar* pointer directly, because the + pixel format depends on the byte order on the underlying platform. Use + qRgb() and friends (qcolor.h) to access the pixels. + + +QWidget: +-------- + setMouseTracking() does not return bool. Call hasMouseTracking() to + determine the mouse tracking state. (This only affects code that + actually uses the return value.) + + (There are other changes in QWidget, see below) + + +*************** Type changes that might generate warnings: ***************** + + +QCache/QIntCache: +----------------- + Using int/uint instead of long/ulong. + + +QDate/QTime/QDateTime: +---------------------- + Using int/uint instead of long/ulong (MS-DOS required long). + + +QIODevice/QBuffer/QFile: +------------------------ + Using int/uint instead of long/ulong. + + +QKeyEvent: +---------- + ascii() now returns int (previously uchar). + + +QTableView: +------------ + uint used instead of ulong (tableFlags() etc.) + + +QTextStream: +------------ + int used instead of long (flags() etc.) + + +***************** Obsoleted functions ********************** + +QAccel: +------- + enable(), disable() and isDisabled() are obsolete. + Use setEnabled(TRUE/FALSE) and !isEnabled() instead. + isItemDisabled(), enableItem(), disableItem() are obsolete. + Use !isItemEnabled(), setItemEnabled(TRUE/FALSE) instead. + + +QApplication: +------------- + cursor(), setCursor() and restoreCursor() obsoleted. + Use overrideCursor(), setOverrideCursor() and restoreOverrideCursor() + instead. + + +QBitmap: +-------- + Constructor takes "const uchar *bits" instead of "const char *" + because of sign problems (uchar = unsigned char). Old constructors are + obsolete. + + +QButton: +-------- + toggleButton() is obsolete, renamed to isToggleButton(). + + +QColor: +------- + The functions QRED, QGREEN, QBLUE, QRGB, QGRAY obsolete. + Instead, use qRed, qGreen, qBlue, qRgb, qGray. + + +QComboBox: +---------- + setStrList() obsolete, use clear() + insertStrList() instead. + string() obsolete, use text() instead. + + +QLCDNumber: +---------- + longValue() is obsolete, use intValue() instead. + + +QListbox: +--------- + The macro LBI_String is obsolete, use LBI_text instead. + string() obsolete, use text() instead. + stringCopy() and setStringCopy() are obsolete. + + +QMenuData: +---------- + string() obsolete, use text() instead. + isItemDisabled(), enableItem(), disableItem() are obsolete. + Use !isItemEnabled(), setItemEnabled(TRUE/FALSE) instead. + checkItem() and uncheckItem() are obsolete. + Use setItemChecked(TRUE/FALSE) instead. + + +QPainter: +--------- + + drawBezier() is obsolete, general Bezier curves are rarely used and + cost too much. Qt will only support drawQuadBezier() (four-point + Bezier) in the future. + +QPointArray: +----------- + move() is obsolete, use translate() instead. + bezier() is obsolete, general Bezier curves are rarely used and + cost too much. Qt will only support quadBezier() (four-point + Bezier) in the future. + + + +QRect: +------ + move() is obsolete, use moveBy() instead. + setTopLeft(), setTopRight(), setBottomLeft(), setBottomRight() and + setCenter() is obsolete, use moveTopLeft(), moveTopRight(), + moveBottomLeft(), moveBottomRight() and moveCenter() instead. + + +QRegion: +------- + move() is obsolete, use translate() instead. + + +QSocketNotifier: +---------------- + enabled() is obsolete. Use isEnabled() instead. + + +QWidget: +-------- + enable(), disable() and isDisabled() are obsolete. + Use setEnabled(TRUE/FALSE) and !isEnabled() instead. + + setMinimumSize(), setMaximumSize(), minimumSize(), maximumSize() are obsolete + use setMinSize(), setMaxSize(), minSize(), maxSize() instead. + + enableUpdates() obsolete, use isUpdatesEnabled()/setUpdatesEnabled(). + + id() is obsolete, it has been renamed to winId(). + +***************** All other changes from 0.95 to 0.96 ********************** + +moc +---------- + Gives a warning if no output is generated. + + +qglobal.h: +---------- + INT32 and UINT32 typedefs changed to work with DEC Alpha. + + +QApplication: +------------- + clipboard() is new. + + +QButtonGroup: +------------- + Exclusive group setting added (isExclusive and setExclusive). + find() is new. + + +QColor: +------- + New type QRgb (uint), used for RGB triplet. + + +QLineEdit: +---------- + You can now mark text, and copy and paste to/from the clipboard. + + +QPaintDevice: +--------- + The bitblt function now takes an ignoreMask parameter. It has a default + value, so no old code will be broken. + +QPrinter: +------------ + fixed minor bugs in handling of polygons and beziers. + + +QWidget: +-------- + New protected virtual functions styleChange(), backgroundColorChange(), + backgroundPixmapChange(), paletteChange() and fontChange(). + These functions are called from setStyle(), setBackgroundColor() etc. + You can reimplement them to if you need to know when widget properties + changed and to optimize updates. + + The destroyed() signal has been moved to QObject. + |
