winEvent()

bool QETWidget::winEvent ( MSG *  message, long *  result  )

inlinevirtual

This special event handler can be reimplemented in a subclass to receive native Windows events which are passed in the message parameter.

In your reimplementation of this function, if you want to stop the event being handled by Qt, return true and set result to the value that the window procedure should return. If you return false, this native event is passed back to Qt, which translates the event into a Qt event and sends it to the widget.

Warning

This function is not portable.
