* Win: QLineEdit not updating correctly when embedded in Graphics ViewBjoern Erik Nilsen2009-05-071-1/+2
| | | | | | | | | | | | | | | | | | | | Updates triggered by the line edit itself, i.e. cursor blinking, are not processed after the top-level is resized. This is yet another problem caused by the event dispatcher on Windows (Qt posted events are not sent during top-level resize, task 146849). We added a work-around for that particular case by posting an event via Windows, but the widget is not visible on the screen (hidden from Windows' POV) so it'll never be posted. And of course then we'll never receive it and the backing store is not synced. This work-around is therefore useless for widgets that are not visible on the screen. However, not receiving update requests while resizing the top-level (in this case QGraphicsView), is not a problem for embedded widgets because all items and hence the proxied widgets are repainted by graphics view anyways.

* Mac: Fixes a crash in tst_QWidget::updateOnDestroyedSignalBjoern Erik Nilsen2009-04-291-0/+3
| | | | | | | | | | Addendum to change 9b674ddcea7c0ff7912f185474b7d98bc83bd39f. The problem was that QWidget::paintEngine() (pure virtual) was called while being in the destructor. The use-case itself (see above change) is very very corner case, but still, it shouldn't crash. Reviewed-by: bnilsen
* Fixes wrong QPaintEvent::region() in QGLWidget::paintEvent.Bjoern Erik Nilsen2009-04-271-2/+9
| | | | | | | | | | | | | | QGLWidget does not support partial updates unless the context is single buffered and auto-fill background is disabled. The problem was that QPaintEvent::region() returned the requested update region without taking into account the limitation of QGLWidget. If QGLWidget doesn't support partial updates, it means everything has to be updated, and QPaintEvent::region() must return the whole widget rect. Auto test included.
