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.
