It can still handle native separators for + Windows. To convert the Qt separators to native separators use + QDir::toNativeSeparators(). + +- QGraphicsTextItem + Tab input is send to the document by default, inserting a <tab> + character. You can get the old behavior of switching Tab focus by + setting setTabChangesFocus(true) (QGraphicsTextItem's Tab handling now + behaves identically to QTextEdit and QTextBrowser). + +- QGraphicsView + QGraphicsView now propagates Qt::Key_Tab and Qt::Key_Backtab to the + scene, which sends this to the items. Similar to how QWidget works, + this event is caught in QGraphicsItem::sceneEvent() and + QGraphicsWidget::event() to handle tab input. Tab input is also + proxied to embedded widgets. This allows and item or widget to handle + Tab keys (e.g., text input). + +- QLocale + The locale database was updated to the Unicode CLDR database + version 1.6.1 + + When the system locale is changed, the LocaleChange event will + be sent to all widgets that don't have a locale explicitely + set. + +- QWebPage + Starting with Qt 4.5, the base brush is used for the default + background color of the web page. Before, it was the background + brush. + +- QWidget + Font and palette settings assigned to QWidget directly take + precedence over application fonts and palettes. + + Focus policies that are set on a widget are now propagated to + a focus proxy widget if there is one. + + Windows with fixed size (that are set with QWidget::setFixedSize() + function or Qt::MSWindowsFixedSizeDialogHint window hint) might + not have a maximize button on the titlebar. + + The behaviour of the window hints was changed to follow the + documentation. When the Qt::CustomizeWindowHint is set, the + window will not have a titlebar, system menu and titlebar + buttons unless the corresponding window hints were explicitely + set. + + Setting Qt::WA_PaintOnScreen no longer has any effect on + normal widgets. The flag can still be used in conjuction with + reimplementing paintEngine() to return 0 so that GDI or + DirectX can be used, as previously documented. |
