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.
Parameters
point-

guintThe touch point index, with 0 being the first touch point received by the action.
delta_x-
Type:
gfloat*Return location for the X delta.
The argument will be set by the function. The argument can be NULL. delta_y-
Type:
gfloat*Return location for the Y delta.
The argument will be set by the function. The argument can be NULL.
