Move a control surface in front of all other control surfaces belonging to a widget
int PtSurfaceToFront( PtWidget_t *widget,
PtSurface_t *surface );
int PtSurfaceToFrontById( PtWidget_t *widget,
unsigned char surface_id );
ph
These functions move a surface in front of all other surfaces
belonging to the given widget.
They differ in how they identify the control surface:
- PtSurfaceToFront()
- Uses the surface argument, which points to a
PtSurface_t structure that describes the control surface.
This pointer must not be NULL.
- PtSurfaceToFrontById()
- Searches the control surfaces belonging to the widget for the one
with an ID of surface_id.
- 0
- Success.
- -1
- The specified surface couldn't be found.
