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.
