\class WindowWrapper client.h
\brief The WindowWrapper class encapsulates a client's managed
window.
There's not much to know about this class, it's completley handled by
the abstract class Client. You get access to the window wrapper with
Client:.windowWrapper(). The big advantage of WindowWrapper is,
that you can use just like a normal QWidget, although it encapsulates
an X window that belongs to another application.
In particular, this means adding a client's windowWrapper() to a
QLayout for the geometry management. See StdClient for an example
on how to do this.
