Platform-Specific Issues ------------------------ Windows: - Drag and drop Ignore drag and drop events for modally shadowed windows. - Build system Fixed qmake problem with QMAKE_EXTRA_WIN_TARGETS. - QApplication Fixed restoring of windows when minimized using something other than the window menu. When restoring a modally blocked application after using "Minimize All Windows" from the task bar, activate the modal dialog rather than the blocked window. Support Unicode application directories in applicationFilePath() independently of the current locale. Fixed accelerators with Ctrl+@ and Ctrl+[ to Ctrl+_ instead. - QAxWidget Fixed bug that could lead to windows no longer responding to mouse events. Fixed bug that would eat a mouse release event in some cases. - QFileDialog Don't let getOpenFileName() fail immediately, even if passed invalid characters. Fixed bug that gave spurious mouse move events to other widgets when closing a file (or printer) dialog. - QFontDatabase Select correct font when family is empty and style hint is set. Fixed problem where Chinese fonts were a pixel smaller than with older Qt versions. - QFtp Improved performance by increasing buffer sizes. - QLocale Obtain correct locale information on Win95, so that QTextCodec::locale() works properly. - QPixmap Fixed problems when alpha blending in 32bpp depth. - QPrinter Fixed problems caused by printing without first calling setup() when using certain printers. - QSettings Fixed bug that would add unnecessary size to the registry on Win98 in some circumstances. - QSocket Worked around Windows bug which caused bytesAvailable() to be 1, even if no data was available. - QSound Removed race condition. - QTextEngine Draw CJK compatibility characters in the 0xffxx range correctly. Fixed crash on invalid UTF-8 when using the newest Uniscribe library on XP. - QWidget Don't clear the maximized state when moving a maximized window. Don't move the widget to a silly position when showMinimized() is called on a visible widget. Let the size grip respect the same size limits as the window manager. Fixed bug where a widget with an empty region as mask would still have one visible pixel. - QWindowsStyle Always underline accelerator cues on Windows 98. - QWindowsXPStyle Draw up/down buttons of QDateTimeEdit disabled when the widget is disabled. Draw toggle-toolbuttons as toggled even if they are not in a toolbar. Mac: - Drag and drop Fixed bug that would disrupt drag and drop when toggling full-screen status. Ignore drag and drop events for modally shadowed windows. Show the correct cursor when copying. - QApplication Fixed bug that could cause crash when allocating and deleting QApplication repeatedly. Properly animate the toolbar button. - QAquaStyle Made sure that OK and Cancel buttons are big enough when icons are added. Fixed bug that would show focus rectangles around hidden widgets in a QScrollView. Fixed drawing errors in QComboBox and QSpinBox when building on Panther and deploying on Jaguar. Fixed bug that caused artifacts on the focus widget when embedded inside a widget with a background pixmap. - QComboBox Fixed crash when calling setListBox() and later popping up the popup list.

Fixed crash when using the QApplication( Display *,...) constructor without any settings file in ~/.qt/. Fixed bug when passing a Tk Visual* to the QApplication constructor. - QClipboard Fixed race condition in clear(). - QFontDatabase Fixed bug that caused some special TTF fonts to display incorrectly. Fixed bug where Qt would not find some non-scalable fonts. - QFontEngine Fixed bug that caused incorrect metrics and drawing in some cases when a painter scales down very large fonts for display. - QMotif Fixed crash when passing X11 command line parameters. Fixed GUI freeze when using the system close menu on a QMotifWidget window with some window managers. - QPainter Fixed memory leak when more than 256 GCs are allocated. - QPrinter Allow multiple space-separated options in setPrinterSelectionOption(). Fixed printing to A3 sized paper. Fixed printing using certain PFB fonts (e.g. the ones generated from TeX). - QWidget Fixed restoration from fullscreen/maximize on non-EWMH supporting window managers. Do not clear the fullscreen/maximize state if the window manager ignores a resize request from Qt. Worked around bugs in window placement for the SGI 4Dwm window manager. Embedded: Makeqpf tool Use the same way of finding the font directory as the rest of Qt. - QVNCServer It is now possible to have several different VNC servers active on the same machine (and even in the same process). Fixed bug connecting a little-endian client to a big-endian server. - QPainter Fixed bug making thick vertical lines one pixel too wide. Worked around compiler bug in gcc 3.3.1 and 3.3.3 (but apparently not in 3.3.2), causing artifacts when drawing anti-aliased text on 16-bpp displays in release mode. - QWidget Avoid creating a paint event in setMask() if the new mask is the same as the old. - QWSManager Fixed crash when widget is deleted during a window system mouse grab. Only move window on left mouse press. - QWSServer Avoid possible race condition in sendPropertyNotifyEvent() when client quits.
