Followed by a detailed list of +changes in the API. + + +The Qt Library +======================================== + +QCom postponed +-------------- + +Previous Qt 3.0 betas introduced a module called QCom that provides a +COM-like component system. The feedback we received on this module +during the 3.0 beta phase has been mixed. Many users think this module +lacks the intuitiveness and compactness that they have learned to +expect from a Qt API. Therefore, we have made the difficult decision +to withdraw the QCom API from the Qt 3.0 release. We will continue to +develop this API until it is evolved enough for our customers, and +will include the improved version in a later release. + +We apologize for any inconvenience the QCom API change has +caused. This decision was made as part of our ongoing efforts to +maintain the soundness and quality of Qt. + +Please note that the new plugin functionality in 3.0 will still be +provided. This includes using custom widgets in Qt Designer, as well +as runtime addition of styles, codecs, SQL drivers, and image format +handlers. This functionality is now available through a substantially +simplified API. + +Also also note that it will still be convenient to add custom plugin +capabilities to Qt 3.0 applications, since the new QLibrary class will +still be available. This class takes care of the low-level, +platform-dependent issues regarding loading of DLLs and obtaining +pointers to the functions exported by the DLLs. + + +Qt Designer +======================================== + + - Improvements to the Designer reference manual. + + - Improved the C++ code indenter in the editor for numbers and + handling of parenthesis. + + +Qt Assistant +======================================== + + - Added a context menu with common commands. + + - Allow multiple windows to be opened and added the common shortcut + that Shift+Click on a link opens the link in a new window. + + +Qt Functions +======================================== + +QAccel +------ + + - Try harder to ensure that accelerators continue to work when a top + level widget is reparented into another window. + +QColor +----- + + - X11 only: better heuristic to decide if you use black or white when a + color could not be allocated. + - win32 only: improve color allocation on 8bit displays, e.g. when + using a terminal server. + +QComboBox +--------- + + - Added a new function to be able to set a custom line edit. + +New function: + virtual void setLineEdit( QLineEdit *edit ); + +QCString +-------- + + - Implemented a dummy out-of-line destructor for QCString to help the + compiler to optimize the number of conflicts as the location of a vtable + is now known. + +QCursor +------- + + - win32 only: Added a constructor that takes a platform specific handle. + +New function: + QCursor( HCURSOR ); (win32 only) + +QDateTime and QDateTimeEdit +--------------------------- + + - win32 only: better handling of localization settings. + +QDockWindow +----------- + + - Remeber last size of an undocked window, so when it is docked and + undocked again, use this size again. + +QDom +---- + + - Fixed an infinite loop in QDomDocument::toString(). + +QFileDialog +----------- + + - Improved handling of "~" to make it work as a directory. + +QFileInfo +--------- + + - win32 only: permissions respects the read-only attribute now. + +QIconView +--------- + + - Added a function to find out whether an item in a view is currently + being renamed. + - Fixed a crash. + +New function: + bool isRenaming() const; + +QInputDialog +------------ + + - Improved the handling of double input formats. + +QListView +--------- + + - Added a function to find out whether an item in a view is currently + being renamed. + - Fixed a possible infinite loop. + - Improved spacing handling for columns that can show a sort indicator. + +New function: + bool isRenaming() const; + +QMainWindow +----------- + + - Make menuAboutToShow() protected to allow customized dock menus. + - Fixed spacing problem for menu bars. + +QMap +---- + + - Fixed infinite looping in count( const Key& k ). + +QObject +------- + + - The slot deferredDelete() was renamed to deleteLater() to be more + intuitive. Code that used deferredDelete() has to be adjusted for the + new name. + +New function: + void deleteLater(); + +QPainter +-------- + + - Fixed bounding rectangle when printing richtext. + - Restore brush origin in QPainter::restore(). + +QPixmap +------- + + - X11 with render extension only: better support for alpha blending: + - QPixmap::xForm() keeps now the alpha channel information + - alpha channel information is kept when copying QPixamps + - alpha blending works with QMovie + - tiling pixmaps with alpha channel works now + +QPrinter +-------- + + - Unix only: fixed dashed line drawing when using high resolution + printing. + - Better printing detection on Irix. + +QRadioButton +------------ + + - Fixed focus problem for radio buttons in a button group. + +QSqlCursor +---------- + + - Fixed primeInsert() to work if the primary key of the edit buffer has + changed. + - Changing primary index keys now also works if the cursor's position + moved in the meantime. + +QStyle +------ + + - Added a base value (CC_CustomBase) for custom defined primitives, + controls, etc. -- this allows custom widgets to use the new style + engine. + - Fixed spacing problem for custom menu items. + - Improved the look of the Motif plus and the SGI style. + +QTable +------ + + - Fixed a crash when drag source is the current table editor widget. + - Fixed a bug that prevented having different colors in different cells. + +QTabletEvent +------------ + + - Improved Watcom tablet support to allow multiple devices to be used. + +QTextEdit +--------- + + - Better handling for font sizes in the font tag. + - Parse the qt tag again. + - Fixed text() for read-only documents. + - Improved right mouse button menu handling. + - New function to pass the position to the createPopupMenu() function for + improved flexibility. + +New function: + virtual QPopupMenu *createPopupMenu( const QPoint& pos ); + +QThread +------- + + - Unix only: Make sure that the seconds and nano-seconds in the sleep + functions are within the limits. + +QUrlInfo +-------- + + - Added the concept of invalid QUrlInfo objects. This is useful in + conjunction with QUrlOperator::info(). + +New function: + bool isValid() const; + +QWizard +------- + + - Set the previous pages nextEnabled to TRUE if we add a page to the end + of a wizard. + +QWMatrix +-------- + + - mapRect() returns always a valid QRect now. + +QWorkspace +---------- + + - Update the titlebar when toggling shaded/non-shaded. + - Update the titlebar to be deactivated when the application's activation + status changes. + - Improve placement of document windows.
