Method
ClutterPanActionget_motion_delta
Declaration [src]
gfloat
clutter_pan_action_get_motion_delta (
ClutterPanAction* self,
guint point,
gfloat* delta_x,
gfloat* delta_y
)
Description [src]
Retrieves the delta, in stage space, dependent on the current state
of the ClutterPanAction
. If it is inactive, both fields will be
set to 0. If it is panning by user action, the values will be equivalent
to those returned by clutter_gesture_action_get_motion_delta().
If it is interpolating with some form of kinetic scrolling, the values
will be equivalent to those returned by
clutter_pan_action_get_interpolated_delta(). This is a convenience
method designed to be used in replacement “pan” signal handlers.
