NAME

       glutTabletButtonFunc - sets the special keyboard callback for the current 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
       window has tablet input focus (normally, when the mouse is in the window) and the user generates tablet button presses. The button  parame-
       ter   will   be	the  button  number  (starting	at  one).  The	number	of  available  tablet  buttons	can  be  determined  with  glutDe-
       viceGet(GLUT_NUM_TABLET_BUTTONS). The state 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 tablet button state changed.

       Registering  a tablet button callback when a tablet device is not available 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
       callback is initially registered.
