void QmitkRenderWindow::SetResendQtEvents ( bool  resend ) [virtual]

Whether Qt events should be passed to parent (default: true)

With introduction of the QVTKWidget the behaviour regarding Qt events changed. QVTKWidget "accepts" Qt events like mouse clicks (i.e. set an "accepted" flag). When this flag is set, Qt fininshed handling of this event -- otherwise it is reached through to the widget's parent.

This reaching through to the parent was implicitly required by QmitkMaterialWidget / QmitkMaterialShowCase.

The default behaviour of QmitkRenderWindow is now to clear the "accepted" flag of Qt events after they were handled by QVTKWidget. This way parents can also handle events.

If you don't want this behaviour, call SetResendQtEvents(true) on your render window.
