Revision control
++ Qt 3.0 Beta6 is not binary compatible with Beta5; any programs linked
++ against Beta5 must be recompiled.
++
++ Below you will find a description of general changes in the Qt
++ Library, Qt Designer and Qt Assistant. 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.
