Qt 3.0.6 is a bugfix release. It maintains both forward and backward compatibility (source and binary) with Qt 3.0.5 **************************************************************************** * General * **************************************************************************** BINARY COMPATIBILITY WARNING: Qt 3.0.6 is binary compatible with Qt 3.0.5, and is planned to be binary compatible with Qt 3.1. Unfortunately Qt 3.0.5 is not 100% binary compatible with Qt 3.0.3. We did not realise there was a binary incompatibility in the Qt 3.0.3 package until after it had already been widely distributed in various GNU/Linux distributions. We have decided to stick with 3.0.5's ABI, which differs from 3.0.3 in that the QTextEdit class has become a few bytes smaller. This means that programs compiled with Qt 3.0.5 that use QTextEdit or any QTextEdit subclass will not run properly when run with Qt 3.0.3. If you ship dynamically linked exectuables, we suggest putting a QT_REQUIRE_VERSION macro at the beginning of your main function: ... #include ... int main( int argc, char**argv ) { QT_REQUIRE_VERSION( argc, argv, "3.0.5" ) ... } The macro will show a message box with a warning message and then abort the application gracefully with exit(1). **************************************************************************** * Library * **************************************************************************** - QAccessible Windows only: No sound for message boxes without icons. - QAction: Implemented resetting QAction's iconSet property, if a null-iconset is passed as argument. Don't update when nothing has changed. - QActionGroup: Synchronize comboboxes correctly for groups with separators. Set the initial currentItem of comboboxes to the action that is on when adding the group. Emit the activated signal for non-toggle actions selected from a combobox. Apply the state of the action group for new widgets. - QApplication: Windows only: Reserve more space for very long application filenames. - QAquaStyle: Mac only: Eliminate drawing artifacts for lineedits. Fixed painting headers. - QCanvas: setBackgroundPixmap( QPixmap() ) now clears the background pixmap. - QCheckBox: Fixed sizeHint() to be wide enough when showing a pixmap. - QCheckTableItem: Implemented sizeHint(). Use the colorgroup passed in for the background color instead of the viewport's colorgroup. - QColor: Make empty names invalid in setNamedColor(). Windows only: Fixed palette allocation and ManyColor mode. - QComboTableItem: Implemented sizeHint(). - QDataTable: Fixed cancelling inserts/updates with the Esc key. Windows only: If confirmation is switched on and the user cancels an update by clicking in a different field, don't change the current row. Made QDataTable respect read-only columns. Made adjustColumn() work properly. - QDateTime: QDate::fromString( date.toString(Qt::TextDate), Qt::TextDate ) now works for locales where weekdays aren't three letters (e.g. Dutch). - QDesktopWidget: Windows only: Allow explicit creation of QDesktopWidgets. - QDir: Windows only: Reset the directory list before returning from the floppy-drive-case. Return a backslash from QDir::separator. - QDockWindow: Fixed getting the coordinates right when moving dockwindows when there are toplevel dock areas. Don't pass window activation around unnecessarily when the activation is ignored anyway (this fixes repaint errors when dragging dock windows on Windows). Remove floating windows from internal lists when deleting. - QDomDocument: The indent argument of the QDomNode::save() function now works properly for recursive subnodes as well. - QFileDialog: Windows only: Improved population speed. Works properly with network paths. - QFileInfo: Windows only: Fix crash when calling doStat() with a null file name. Lookup file permissions for the current user, not for the owner. - QFtp/QUrlOperator Files of size 0 can now be uploaded. - QGLContext: Added a workaround to get overlays to work on ATi FireGL cards. Windows only: If the current context was swapped without Qt's knowledge it was impossible to actually reset the context properly. - QHeader: Draw the sort arrow at the right position with multi-line header labels. Respect the orientation in sizeHint(). Repainting fixes. - QIconView: Improved Key_Up/Key_Down navigation. Optimize updates on focus/window activation changes. Prevent double insertion, and reset iconview to zero when taking out an item. - QLibrary: Unix only: Compile for a.out platforms. Windows only: Only append ".dll" extension if no extension has been provided. - QLineEdit: Fixed undo redo when selecting text and replacing it with new text. Allow AlignHCenter and AlignRight for Password'ed lineedits. Don't ignore changes of alignment after setting it to AlignJustify once. Fixed background. X11 only: Clear line edit with CTRL+U. - QListBox: Don't call ensureCurrentVisible() in resizeEvent unless the current item was visible when you started resizing. Fixed contextMenuRequested() signal emission (the item parameter was sometimes wrong). Don't select items that are not selectable. - QListView: Emit expanded() and collapsed() _after_ the items have been expanded or collapsed and all calculations have beed done. Don't call cancelRename() when the rename was OK'd. Don't paint contents when columns() == 0. When showing a tooltip make sure it's only for that column and not for the whole item. Set sorting to dirty after renaming an item. - QMainWindow: Emit dockWindowPositionChanged() from moveDockWindow(). Close all the main window's floating dockwindows in the close event. - QMultiLineEdit: Fixed cursorPoint().y(). - QMYSQLDriver: Prevent warnings to be emitted when dealing with date/time fields that have NULL values. - QOCIDriver: Fixed a memory leak. The environment, error and service handles were only released if a connection to a database was made. - QODBCDriver: Fixed two memory leaks. Fixed support for reading/writing BLOBs through ODBC. Added support for connecting to a file DSN. Added a workaround that makes the QODBC driver work with Informix ODBC under unixODBC. Made the PostgreSQL ODBC driver work properly. - QPixmap: X11 only: Allow QPixmap::grabWindow to work on a screen other than the default one. Windows only: Fixed grabWindow() which grabbed one pixel too many. Fixed the rendering and formatting of centered text that ended with a newline. - QPopupMenu: Added Shift+Key combination to auto accelerators. Draw submenu items disabled if the submenu is disabled. - QProcess: Unix only: Avoid zombie processes if you try to start a non-existent program. Don't eat the file descriptors if a lot of processes (with short runtimes) are started immediately one after the other. Windows only: make the tryTerminate() function work for windows applications (it still does not work for console applications, though). - QPrinter: Windows only: Fixed printing 32-bit images. - QPSQLDriver: Prevent warnings to be emitted when dealing with date/time fields that have NULL values. Windows only: Make the driver compile with the standard PostgreSQL source distribution under Windows. - QRadioButton: Fixed sizeHint() to be wide enough when showing a pixmap. - QSettings: Correct documentation for removeEntry. Windows only: Fixed off-by-one for keys ending with a slash. - QSocket: Fixed crash when readBlock() returns 0. - QTable: Less flicker in table headers. Fixed emitting selectionChanged() when selecting cells with the mouse. Crash fix. Fixed adjustRow() and adjustColumn() for multi-span cells. Don't allow the current row/column to be larger than the number of rows/columns in a table. Set the table of the item in insertItem() correctly. Reset table pointer to zero when taking item out of the table. Fixed Tab/BackTab handling. - QTextEdit: Return a useful default in paper(). Support paletteBackgroundColor properly. Fixed ensureCursorVisible() if the text is not completly formatted yet. Crash fix when word wrapping, backspacing and adding a new paragraph. Fixed repaint problems. Windows only: CTRL+Key_A (select all) now also works in a read only text edit. - QThread: Windows only: Avoid unnecessary call to TerminateThread. - QToolButton: Toolbuttons with popups that have a margin align the popup correctly. - QToolTip: Make sure the tooltip is displayed on the correct screen (i.e. on multi-head systems) for big widgets. - QTranslator: Better error checking when loading .qm files. - QUrl: Recognize Windows drive letters not only in the form of "c:/" but also in the form "c:", (i.e. without the '/'). - QVariant: QDate can convert to QDateTime. - QWidget: Pass the old activation state to windowActivationChange(). Avoid endless loops when a popup widget refuses to close. - QWindowsStyle: Made the Windows style use the system's scrollbar width. - Richtext Engine: append() starts a fresh new paragraph and clears list item and depth properties. Parse all entities up to 8 characters. Optimized text drawing speed. Many rendering fixes and improvements. Parsing fixes.
