void
glutMotionFunc(void( *callback )( int x, int y ));

Client hook for dragging mouse.

This function reports the mouse position when the mouse is dragged starting from within your window. (``Dragging'' occurs when you press one or more mouse buttons in one of your OpenGLUT windows, and then move the mouse around.)

This callback is bound to the


current window
.

Events are reported until the mouse button is released, even if the mouse leaves the window.

Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent.
