The state callback parameter is either GLUT_LEFT or GLUT_ENTERED depending on if the mouse pointer has last left or entered the window. Passing NULL to glutEntryFunc disables the generation of the mouse enter/leave callback. Some window systems may not generate accurate enter/leave callbacks. X IMPLEMENTATION NOTES An X implementation of GLUT should generate accurate enter/leave callbacks. .SH SEE ALSO glutMotionFunc, glutCreateWindow .SH AUTHOR Mark J. Kilgard (mjk@nvidia.com)
