glutMotionFunc, glutPassiveMotionFunc - set the motion and passive motion
callbacks respectively for the current window.
void glutMotionFunc(void (*func)(int x, int y));
void glutPassiveMotionFunc(void (*func)(int x, int y));
- func
- The new motion or passive motion callback function.
glutMotionFunc and glutPassiveMotionFunc set the motion and passive motion
callback respectively for the current window. The motion callback for a window
is called when the mouse moves within the window while one or more mouse
buttons are pressed. The passive motion callback for a window is called when
the mouse moves within the window while no mouse buttons are pressed.
The x and y callback parameters indicate the mouse location in
window relative coordinates.
Passing NULL to glutMotionFunc or glutPassiveMotionFunc disables
the generation of the mouse or passive motion callback respectively.
