// -*-c++-*- osgWidget - Code by: Jeremy Moles (cubicool) 2007-2008
// $Id: osgwidgetbox.cpp 59 2008-05-15 20:55:31Z cubicool $
// NOTE: You'll find this example very similar to osgwidgetwindow. However, here we
// demonstrate a bit of subclassing of Widget so that we can respond to events
// such as mouseEnter and mouseLeave. We also demonstrate the use of padding, though
// fill and alignment should be working too.
