GesturePan

#GtkGesturePan is a #GtkGesture implementation able to recognize pan gestures, those are drags that are locked to happen along one axis. The axis that a #GtkGesturePan handles is defined at construct time, and can be changed through gtk.gesture_pan.GesturePan.setOrientation.

When the gesture starts to be recognized, #GtkGesturePan will attempt to determine as early as possible whether the sequence is moving in the expected direction, and denying the sequence if this does not happen.

Once a panning gesture along the expected axis is recognized, the #GtkGesturePan::pan signal will be emitted as input events are received, containing the offset in the given axis.

From GestureDrag

_getGType GType _getGType()
_gType GType _gType [@property getter]
self GestureDrag self(): Returns this, for use in with statements.
builder GestureDragGidBuilder builder(): Get builder for gtk.gesture_drag.GestureDrag
getOffset bool getOffset(double x, double y): If the gesture is active, this function returns true and fills in x and y with the coordinates of the current point, as an offset to the starting drag point.
getStartPoint bool getStartPoint(double x, double y): If the gesture is active, this function returns true and fills in x and y with the drag start coordinates, in window-relative coordinates.
connectDragBegin gulong connectDragBegin(T callback, Flag!"After" after): Connect to DragBegin signal.
connectDragEnd gulong connectDragEnd(T callback, Flag!"After" after): Connect to DragEnd signal.
connectDragUpdate gulong connectDragUpdate(T callback, Flag!"After" after): Connect to DragUpdate signal.
