glutEntryFunc - sets the mouse enter/leave callback for the current window.
void glutEntryFunc(void (*func)(int state));
- func
- The new entry callback function.
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.
