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.
