glutTabletButtonFunc(3GLUT)	     GLUT	   glutTabletButtonFunc(3GLUT)

NAME
       glutTabletButtonFunc  - sets the	special	keyboard callback for the cur-
       rent window.

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

ARGUMENTS
       func	 The new tablet	button callback	function.

DESCRIPTION
       glutTabletButtonFunc sets the tablet button callback  for  the  current
       window. The tablet button callback for a	window is called when the win-
       dow has tablet input focus (normally, when the mouse is in the  window)
       and the user generates tablet button presses. The button	parameter will
       be the button number (starting at one). The number of available	tablet
       buttons	can be determined with glutDeviceGet(GLUT_NUM_TABLET_BUTTONS).
       The state is either GLUT_UP or GLUT_DOWN	indicating whether  the	 call-
       back  was  due to a release or press respectively. The x	and y callback
       parameters indicate the window relative	coordinates  when  the	tablet
       button state changed.

       Registering a tablet button callback when a tablet device is not	avail-
       able is ineffectual and not an error. In	this case,  no	tablet	button
       callbacks will be generated.

       Passing	NULL to	glutTabletButtonFunc disables the generation of	tablet
       button callbacks. When a	new window is created, no tablet button	 call-
       back is initially registered.
