- The new entry callback function.
- .SH 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.
