Library

OpenGLUT - input

Synopsis

#include <openglut.h>

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

Parameters


callback


Client mouse-glide hook.

Description

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


callback


with the window coordinates of the mouse.

This callback is bound to the


current window


.

Caveats

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