PtCalcSurfaceByAction()
Force all control surfaces associated with an action to calculate their geometry
Synopsis:
void PtCalcSurfaceByAction(
PtWidget_t *widget,
PtWidgetClassRef_t const *cref,
ushort_t action_id );
Library:
ph
Description:
PtCalcSurfaceByAction() forces all surfaces belong to the given widget that are associated with an action to calculate their geometry.
The cref and action_id specify the class and manifest of the action associated with surfaces to be calculated.
