/**
* A QXEmbed widget serves as an embedder that can manage one single embedded
* X-window. These so-called client windows can be arbitrary Qt or non Qt
* applications.
*
* There are two different ways of using QXEmbed,
* from the client side or from the embedder's side.
*
* Embedding from the client's side requires that the client knows the
* window identifier of the respective embedder widget. Use either
* embedClientIntoWindow() or the high-level wrapper processClientCmdline().
* This is only possible when the client is a Qt application.
*
* When using it from the embedder's side, you must know the window
* identifier of the window that should be embedded. Simply call embed()
* with this identifier as parameter. If the client is a Qt application,
* make sure it has called QXEmbed::initialize(). Otherwise you should
* probably call setProtocol(XPLAIN) before embed().
*
* Reimplement the change handler windowChanged() to catch embedding or
* the destruction of embedded windows. In the latter case, the
* embedder also emits a signal embeddedWindowDestroyed() for
* convenience.
*
* @short The QXEmbed widget is a graphical socket that can embed an external X-Window.
