PtShowSurface(), PtShowSurfaceById()

Show a hidden control surface

Synopsis:

int PtShowSurface( PtWidget_t *widget,
                   PtSurface_t *surface );

int PtShowSurfaceById( PtWidget_t *widget,
                       unsigned char surface_id );

Library:

ph

Description:

These functions show a control surface, restoring it from a hidden state. The widget argument specifies the widget owning the surface. The functions differ in how they identify the control surface:

PtShowSurface()
Uses the surface argument, which points to a PtSurface_t structure that describes the control surface. This pointer must not be NULL.
PtShowSurfaceById()
Searches the control surfaces belonging to the widget for the one with an ID of surface_id.

Returns:

0
Success.
-1
The specified surface couldn't be found or wasn't hidden.

Classification:

Photon

Safety:
Interrupt handler No
Signal handler No
Thread No
