Usage

Arguments

func: The new entry callback function.

Overview

glutEntryFunc sets the mouse enter/leave callback for the current window. 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.
