- The new tablet button callback function.
- .SH 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
- 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 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.
