glutShowOverlay(3GLUT) GLUT glutShowOverlay(3GLUT)
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 intensive to use these
routines to control the display status of an overlay as opposed to removing and re-establishing the overlay.
