| Here is a list of (major) changes in Qt from 0.95 to 0.96. |
| |
| Bug-fixes, optimizations and improved documentation, of course. |
| QClipboard is new. |
| |
| There are some changes in the API (Qt header files). 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. |

| 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(), |

| 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. |
