glutTabletMotionFunc(3GLUT)          GLUT          glutTabletMotionFunc(3GLUT)

NAME

       glutTabletMotionFunc  - sets the special keyboard callback for the cur-
       rent window.

SYNTAX

       void glutTabletMotionFunc(void (*func)(int x, int y));

ARGUMENTS

       func      The new entry callback function.

DESCRIPTION

       glutTabletMotionFunc sets the tablet motion callback  for  the  current
       window. The tablet motion 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 motion. The x and y callback parameters
       indicate the absolute position of the tablet ``puck''  on  the  tablet.
       The  callback  parameters are normalized to be within the range of 0 to
       2000 inclusive.

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

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