Structure members

type: GdkEventType: The type of the event (GDK_TOUCHPAD_PINCH).
window: GdkWindow: The window which received the event.
send_event: gint8: TRUE if the event was sent explicitly.
phase: gint8: The current phase of the gesture.
n_fingers: gint8: The number of fingers triggering the pinch.
time: guint32: The time of the event in milliseconds.
x: gdouble: The X coordinate of the pointer.
y: gdouble: The Y coordinate of the pointer.
dx: gdouble: Movement delta in the X axis of the swipe focal point.
dy: gdouble: Movement delta in the Y axis of the swipe focal point.
angle_delta: gdouble: The angle change in radians, negative angles denote counter-clockwise movements.
scale: gdouble: The current scale, relative to that at the time of the corresponding GDK_TOUCHPAD_GESTURE_PHASE_BEGIN event.
x_root: gdouble: The X coordinate of the pointer, relative to the root of the screen.
y_root: gdouble: The Y coordinate of the pointer, relative to the root of the screen.
state: GdkModifierType: A bit-mask representing the state of the modifier keys (e.g. Control, Shift and Alt) and the pointer buttons. See GdkModifierType.
