glutTabletMotionFunc(3GLUT)          GLUT          glutTabletMotionFunc(3GLUT)



NAME
       glutTabletMotionFunc - sets the special keyboard callback for the
       current 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
       window 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
       available 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
       callback is initially registered.
