#include <openglut.h>

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

Client mouse-glide hook.

If you set this callback on a window, then every time that OpenGLUT detects a change in the mouse position inside that window, with no buttons pressed on that mouse, OpenGLUT will invoke

with the window coordinates of the mouse.

This callback is bound to the


current window
.

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