REVISION SUMMARY This change adds global touchpad swipe gestures to the GlobalShortcutsManager and hooks up the swipe gestures as defined at the Plasma Affenfels sprint: - swipe up: Desktop Grid - swipe down: Present Windows - swipe left: previous virtual desktop - swipe right: next virtual desktop The main work is handled by two new classes: SwipeGesture and GestureRecognizer. This is implemented in a way that it can be extended to also recognize touch screen gestures and pinch gestures. The SwipeGesture defines what is required for the gesture to trigger. Currently this includes the minimum and maximum number of fingers participating in the gesture and the direction. The gesture gets registered in the GestureRecognizer. The events for the gesture are fed into the GestureRecognizer. It evaluates which gestures could trigger and tracks them for every update of the gesture. In the process of the gesture tracking the GestureRecognizer emits signals on the Gesture: - started: when the Gesture gets considered for a sequence - cancelled: the Gesture no longer matches the sequence - triggered: the sequence ended and the Gesture still matches The remaining changes are related to hook up the existing shortcut framework with the new touchpad gestures. The GlobalShortcutManager gained support for it, InputRedirection and EffectsHandler offer methods to register a QAction. VirtualDesktopManager, PresentWindows and DesktopGrid are adjusted to support the gesture.
