From 0f8ad242fb9c82e542ace1d2595038edf87f7b3d Mon Sep 17 00:00:00 2001 From: Friedemann Kleint Date: Fri, 20 Jan 2012 08:57:17 +0100 Subject: Add a virtual sendPostedEvents() to QEventDispatcherWin32. Reimplement this in QWindowGuiEventDispatcher to send both Qt posted events and queued QPA window system events. We need to do this at a well defined place, instead of sending events outside of the eventloop from the Windows proc. This fixes various hangs for example in tst_qinputdialog, which used a 0-timer to close a dialog.
