NAME

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

SYNTAX

       void glutEntryFunc(void (*func)(int state));

ARGUMENTS

       func	 The new entry callback function.

DESCRIPTION

       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.

NAME

       glutMouseFunc - sets the mouse callback for the current window.

SYNTAX

       #include <GLUT/glut.h>

       void glutMouseFunc(void (*func)(int button, int state,
			  int x, int y));

ARGUMENTS

       func	 The new mouse callback function.

DESCRIPTION

       glutMouseFunc  sets the mouse callback for the current window. When a user presses and releases mouse buttons in the window, each press and
       each release generates a mouse callback. The button parameter is one of GLUT_LEFT_BUTTON,  GLUT_MIDDLE_BUTTON,  or  GLUT_RIGHT_BUTTON.  For
       systems	with  only two mouse buttons, it may not be possible to generate GLUT_MIDDLE_BUTTON callback. For systems with a single mouse but-
       ton, it may be possible to generate only a GLUT_LEFT_BUTTON callback. The state parameter is either GLUT_UP or GLUT_DOWN indicating whether
       the  callback was due to a release or press respectively. The x and y callback parameters indicate the window relative coordinates when the
       mouse button state changed. If a GLUT_DOWN callback for a specific button is triggered, the program can assume a GLUT_UP callback  for  the
       same  button  will  be  generated (assuming the window still has a mouse callback registered) when the mouse button is released even if the
       mouse has moved outside the window.

       If a menu is attached to a button for a window, mouse callbacks will not be generated for that button.

       During a mouse callback, glutGetModifiers may be called to determine the state of modifier keys when the mouse event generating	the  call-
       back occurred.

       Passing NULL to glutMouseFunc disables the generation of mouse callbacks.
