glutLayerGet(3GLUT) GLUT glutLayerGet(3GLUT) NAME glutLayerGet - retrieves GLUT state pertaining to the layers of the current window. SYNTAX int glutLayerGet(GLenum info); ARGUMENTS info Name of device information to retrieve. GLUT_OVERLAY_POSSIBLE Whether an overlay could be established for the current window given the current initial display mode. If false, glutEstab- lishOverlay will fail with a fatal error if called. GLUT_LAYER_IN_USE Either GLUT_NORMAL or GLUT_OVERLAY depending on whether the normal plane or overlay is the layer in use. GLUT_HAS_OVERLAY If the current window has an overlay established. GLUT_TRANSPARENT_INDEX The transparent color index of the overlay of the current window; negative one is returned if no overlay is in use. GLUT_NORMAL_DAMAGED True if the normal plane of the current window has damaged (by win- dow system activity) since the last display callback was triggered. Calling glutPostRedisplay will not set this true. GLUT_OVERLAY_DAMAGED True if the overlay plane of the current window has damaged (by window system activity) since the last display callback was trig- gered. Calling glutPostRedisplay or glutPostOverlayRedisplay will not set this true. Negative one is returned if no overlay is in use. DESCRIPTION glutLayerGet retrieves GLUT layer information for the current window repre- sented by integers. The info parameter determines what type of layer infor- mation to return.
