gluttabletmotionfunc(3)
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 win
dow is called when the window has tablet input focus (nor
mally, when the mouse is in the window) and the user gen
erates 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 genera
tion of tablet motion callbacks. When a new window is cre
ated, no tablet motion callback is initially registered.
