Detailed Description

OverridingShortcut is a variation of QShortcut which takes precedence over other listeners for the same key sequence.

It does so by reacting on events of type of QEvent::ShortcutOverride. Since these events are of class QKeyEvent, the overriding works only for key sequences consisting of a single key plus modifiers. For multi-key sequences, the shortcut will work like a normal QShortcut.

OverridingShortcut now ignores a ShortcutOverride event if it occurs immediately (within less than 50 milliseconds) after another. This works around an issue which appeared in Qt 5.1.0 where the event filter receives two ShortcutOverride events for a single shortcut key press.
