0004 Subject: [PATCH 07/43] Fix unbalanced KeyPress/Release events in children of
0005  QMdiArea
0006
0007 When the user presses Ctrl+Tab, QMdiArea is supposed to switch
0008 the active child window. When doing so, it eats the event. The
0009 problem is that is doesn't eat the ShortcutOverride event,
0010 which is kept unbalanced with the absent KeyRelease event.
