call in QGraphicsItem. + + * Fixed mouse grabber book-keeping problems in QGraphicsScene which fell out + of sync when opening modal dialogs or popups from within a mouse event + handlers. + + *

the destination buffer. + + * Avoid rounding errors when drawing parts of a pixmap using the Quartz 2D + engine. + + * Added caching of QGradient's color table for the raster paint engine. + This means that if a gradient with the same stops and colors is used + again, it will be quickly fetched from the cache, avoiding the + expensive calculations of the color lookup table. + + * Fixed a crash

drawn + when drawing a path partially outside the viewport using a dashed pen. + + * Fixed an assert in QImage that was triggered when reading PNG files + with certain palettes. + + * Fixed an issue where stroking and drawing aliased QPainterPaths with a + non-cosmetic pen would produce incorrect results. + + * Fixed an issue where text was cut off when drawn onto a QImage. + + * Fixed an issue where text would be drawn onto a QPicture with an + incorrect position. + + * Fixed an issue where enabling/disabling clipping when drawing into a + QImage did not have any effect. + + * Fixed bug in QImage::createHeuristicMask where the color table was not + initialized properly. + +- Qt Resource Compiler (rcc) + + * Improved handling of relative paths in .qrc files. + +- Style Sheets + + * Made general performance improvements. + + * Fixed crash that could occur when a widget with a style sheet was + reparented into a widget with no style sheet. + + * Ensured that a widget's custom palette is not overwritten when not styled + using a style sheet. + + * Added support to allow colors to be specified with alpha components. + + * Added support for group box styling. + + * Removed broken

platforms where qreal values are + not equivalent to double values; i.e., sizeof(qreal) != sizeof(double). + +- QDateTime/QDateTimeEdit + + * Fixed a bug that allowed you to type in larger numbers than 12 in 12-hour + fields. + + * Fixed a bug that occurred when QDate::shortMonthName() was longer than + 3 characters. + + * Improved the handling of left-to-right languages. + +- QDialogButtonBox + + * QDialogButtonBox now sets the default button to the first button with + the Accept role if no other button has explicitly been set as the + default when it is shown. This is to stop a regression where using the + autoDefault property with the Mac and Cleanlooks styles would set the + Cancel button as the default. + +- QDir + + * Fixed an assert in QDir::entryList() when reading file entries with + names containing invalid Unicode encodings. + +- QFileDialog + * Fixed bug that showed a non-existing folder for every space the user typed + after a dot (.) in the lineedit. + +- QFileSystemWatcher + + * Fixed compilation on Linux/HPPA. + +- QFSFileEngine + + * Fixed broken UNC path support. + +- QIODevice + + * Fixed a data corruption bug when

their dock + widgets when using saveState() and restoreState(). + + * Fixed handling of dock widgets that are non-closable to the user so that + they can be programmatically closed. + + * Fixed regression from Qt 4.1.4 behavior to ensure that palette changes + to main windows are also propagated to their children. + +- QMenuBar + + * Improved event handling to avoid sending events when a menu bar has no + parent widget. + +- QObject + + * Fixed memory leak when calling QObject::moveToThread(0). + +- QPainter + + * Fixed reentrancy issue that would otherwise lead to crashes if more than + one QImage is deleted at the same time (from different threads). + +- QPalette + + * Improved handling of the palette obtained from QApplication::palette() + in cases where QApplication::setStyle() has been called before a + QApplication instance has been constructed (as recommended by the + documentation). + +- QPluginLoader + + * Fixed a potential crash that could occur when calling staticInstances() + from a global destructor. + +- QProgressBar + + * Document that drawing of text in vertical progress bars is style-dependent. + +- QSqlRelationalTableModel + + *

issue where tool button popup menus were positioned incorrectly + on multi-screen setups. + +- QTreeView/QTreeWidget + + * Fixed possible assert when painting if there were layouts pending. + + * Fixed possible segfault when a model emits layoutChanged(). + + * Fixed erroneous expanding/collapsing of items when the user + double-clicked in the checkbox area of an item. + + * Fixed a crash in setRowHidden() caused by hiding then un-hiding items + in a hierarchy. + + * Fixed setSortingEnabled() which could could cause incorrect painting. + +- QVariant + + * Fixed behavior where conversion of invalid variants to integers would be + incorrectly reported as successful. + + * Fixed a crash in the compatibility function QVariant::asByteArray() + when called on a null variant. + +- QWidget + + * Made setWindowTitle() work on hidden widgets that are never shown. + (Fixing a bug in QtSingleApplication on Windows.) + + * Made QWidget::restoreGeometry() restore windows to the correct screen + on multi-screen systems. + + * Fixed a bug where the stacking order of widgets would get out of sync + and cause entire widgets, or parts of them, not to be updated properly. + + * Fixed QWidget::setParent() to not recreate the native window ID of + all child widgets when reparenting the parent to top-level. + + * Fixed incorrect resize handling of dock widgets that are resized to the + extent of the screen or to their maximum defined sizes. + +- QWorkspace + + * Fixed memory corruption that caused crashes inside Visual Studio. + +- QMessageBox + + * Made QMessageBox::setText() adjust the size of the text area + when setting a new text. + +- QXmlInputSource + + * Ensured that QXmlInputSource does not read in the whole document at once, + enabling arbitrarily large files to
