+/**
+ * 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.
