the code you quote below is from qwsEventFilter, which is called by
notify().  Are you sure you have overridden notify() correctly?  it's a
public virtual member, so there should not be a problem.

Perhaps you are handling the wrong event?  You should be looking for a
KeyPress event, and check if ((QKeyEvent*)event)->key() == Qt::Key_Escape,
otherwise call the base class function as normal.

see http://doc.trolltech.com/2.3/qwidget.html#70dec1 and
http://doc.trolltech.com/2.3/qt.html#WidgetFlags.  the short answer: no.


PS I should also recommend the qt interest mailing list
(http://lists.trolltech.com/qt-interest/), which is a lot more active than
this one...


hope that helps
