From d7ca800a87a2291c94c6580f0cfe068bb2280caf Mon Sep 17 00:00:00 2001 From: Frederik Gladhorn Date: Thu, 12 Jun 2014 23:42:59 +0200 Subject: Clean up ShortcutOverride handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Instead of sending the event from random places, send it from QWindowSystemInterface. This allows to send override events on OS X to menus before doing other key processing and reduces the number of ShortcutOverride events on all platforms to exactly one per key press event. Additional test by Friedemann Kleint.
