glutshowoverlay(3)
NAME
glutShowOverlay, glutHideOverlay - shows or hides the
overlay of the current window
SYNTAX
void glutShowOverlay(void);
void glutHideOverlay(void);
DESCRIPTION
glutShowOverlay shows the overlay of the current window;
glutHideOverlay hides the overlay. The effect of showing
or hiding an overlay takes place immediately. Note that
glutShowOverlay will not actually display the overlay
unless the window is also shown (and even a shown window
may be obscured by other windows, thereby obscuring the
overlay). It is typically faster and less resource inten
sive to use these routines to control the display status
of an overlay as opposed to removing and re-establishing
the overlay.
