	\class BWindow
	\ingroup interface
	\ingroup libbe
	\brief Window base class.

	A BWindow is an on-screen window which contains views and is the target of
	keyboard and mouse events. A BWindow instance is nearly always subclassed.

	BWindow draws by talking to App Server. If you want draw directly into the
	graphics card by-passing App Server, you need to use a BDirectWindow or
	BWindowScreen.

	Despite the fact that BWindow inherits from BLooper, you should not invoke
	Run() on a BWindow, instead, call Show() to get the message loop started and
	show the window on screen. Once you've called Show() you may remove a window
	from the screen without interrupting the message loop by calling Hide(). Other
	message loop details such as locking and quitting are detailed in the BLooper
	class.

	BWindow has the following built-in shortcuts:

	<table>
