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; glutHideOver-
lay 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.
