Library

OpenGLUT – input

Synopsis

In openglut.h Ft void Fn glutPassiveMotionFunc void( *callback )( int x int y )

Parameters

Bf Em
 callback Ef
    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 Bf Sy
 callback Ef
 with the window coordinates of the mouse.

This callback is bound to the Bf Li
 current window Ef
 .

Caveats

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