Mark a control surface as damaged so that it will be redrawn
void PtDamageSurface( PtWidget_t *widget,
PtSurface_t *surface );
void PtDamageSurfaceById( PtWidget_t *widget,
unsigned char surface_id );
ph
These functions flag a control surface to be redrawn.
The widget argument specifies the widget owning the surface.
The functions differ in how they identify the control surface:
- PtDamageSurface()
- Uses the surface argument, which points to a
PtSurface_t structure that describes the control surface.
This pointer must not be NULL.
- PtDamageSurfaceById()
- Searches the control surfaces belonging to the widget for the one
with an ID of surface_id.
