#### Declaration [src]

    gfloat
    clutter_pan_action_get_constrained_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`, and respecting the constraint specified by the `ClutterPanAction:pan-axis` property.

#### Parameters

`point`

  Type: `guint`

  The touch point index, with 0 being the first touch point received by the action.
