TouchpadEvent

An event related to a gesture on a touchpad device.

Unlike touchscreens, where the windowing system sends basic sequences of begin, update, end events, and leaves gesture recognition to the clients, touchpad gestures are typically processed by the system, resulting in these events.

class TouchpadEvent : Event {

protected

GdkTouchpadEvent* gdkTouchpadEvent;

GdkTouchpadEvent* getTouchpadEventStruct(bool transferOwnership);

void* getStruct();

this(GdkTouchpadEvent* gdkTouchpadEvent, bool ownedRef);

static GType getType();

void getDeltas(double dx, double dy);

GdkTouchpadGesturePhase getGesturePhase();

uint getNFingers();

double getPinchAngleDelta();

double getPinchScale();

}

Constructors

this this(GdkTouchpadEvent* gdkTouchpadEvent, bool ownedRef): Sets our main struct and passes it to the parent class.
