glutUseLayer(3GLUT)                  GLUT                  glutUseLayer(3GLUT)

NAME
       glutUseLayer - changes the layer in use for the current window.

SYNTAX

       void glutUseLayer(GLenum layer);

ARGUMENTS
       layer     Either GLUT_NORMAL or GLUT_OVERLAY, selecting the normal
                 plane or overlay respectively.

DESCRIPTION
       glutUseLayer changes the per-window layer in use for the current
       window, selecting either the normal plane or overlay. The overlay
       should only be specified if an overlay exists, however windows without
       an overlay may still call glutUseLayer(GLUT_NORMAL). OpenGL commands
       for the window are directed to the current layer in use.

       To query the layer in use for a window, call
       glutLayerGet(GLUT_LAYER_IN_USE).
