NAME¶
glutUseLayer —
    Allows you to switch between normal and layer
  mode.
LIBRARY¶
OpenGLUT - overlays
SYNOPSIS¶
#include
    <openglut.h>
void
  
  glutUseLayer(GLenum
    layer);
PARAMETERS¶
layer
Whether to be in a layer or in the normal window.
DESCRIPTION¶
By default, OpenGLUT operates in "normal" mode, with respect to layers. If you have a layer open and wish to operate on the layer, you must use glutUseLayer().
layer
can take on the following values, indicating the layer mode to use:
  
   -
GLUT_NORMAL
  
   -
GLUT_LAYER
CAVEATS¶
Unimplemented.
It is unclear what the consequences are if you are in
GLUT_OVERLAY
mode and switch to another (or the same) window via glutSetWindow(). What if the target has a layer? What if it doesn't?
