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.
