REVISION SUMMARY The Effect class is extended by three new virtual methods: - touchDown - touchMotion - touchUp The methods return a boolean value so that the events can be filtered out. E.g. an effect which has also a mouse grab installed wants to filter out all events, other effects don't need the events exclusively. This is a difference to how e.g. keyboard and pointer events are handled. But is more close to how KWin's internal input event passing works and makes it easier to get touch event: one does not explicitly has to grab the events. It's also closer to Wayland where all input events are available. As a first example the Present Windows effect is adjusted and allows to activate windows through the touch screen. As much code as possible is shared with pointer input.
