Detailed Description

Base class for providing Windowing API agnostic access to creating and managing graphics window and events.

Note, the GraphicsWindow is subclassed from osg::GraphicsContext, and to provide an implementation you'll need to implement its range of pure virtual functions, you'll find these all have naming convention methodNameImplementation(..). GraphicsWindow adds the event queue on top of the GraphicsContext, thereby adding a mechanism for adapting Windowing events as well as basics graphics context work, you should wire up custom GraphicsWindowImplementation to push their events through into the EventQueue.
