glutUseLayer - changes the layer in use for the current window.
void glutUseLayer(GLenum layer);
- layer
- Either GLUT_NORMAL or GLUT_OVERLAY, selecting the normal plane or overlay
respectively.
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).
glutEstablishOverlay, glutSetWindow
