Insert a control surface in front of or behind another
int PtInsertSurface( PtWidget_t *widget, PtSurface_t *surface, unsigned char brother_id, int behind ); int PtInsertSurfaceById( PtWidget_t *widget, unsigned char surface_id, unsigned char brother_id, int behind );
ph
These functions change a surface's z coordinate by inserting the surface in front of or behind another surface. They differ in how they identify the control surface:
The widget argument specifies the widget owning the specified surfaces. The brother_id argument specifies the numerical ID of the surface to position relative to, and the behind argument specifies how to position the surface:
