virtual void OglGui::Carousel3D::MouseFunc	(	int	msg,
		int	btn,
		int	state,
		int	x,
		int	y
	)			`[inline, virtual]`

This function is called by the event handling system everytime the user has moved or clicked the mouse.

So if you want a window which reacts to the mouse in a specific way, you can inherit a class from Window. Another method to implement mouse behaviour is to use a window listener (in this case you have to inherit a class from WindowListener and attach it to this window, see WindowListener for more details)

Reimplemented from OglGui::Window.
