From 10dba674d366260589f3b742e5b1b87ce9ddd47c Mon Sep 17 00:00:00 2001 From: Alexis Menard Date: Mon, 5 Oct 2009 10:20:38 +0200 Subject: Make QEventTransition works with QGraphicsObject. QStateMachine framework installs QObject event filters to catch events in order to triggers the proper transition. But installing a QObject event filter on a QGraphicsObject gives nothing because QGraphicsView events filters works differently. In order to make this works we now post events using QApplication::postEvent in addition to the QGraphicsView events.
