/** Container for widgets from other processes.
* Together with Gtk::Plug, Gtk::Socket provides the ability to embed
* widgets from one process into another process in a fashion that is
* transparent to the user. One process creates a Gtk::Socket widget and,
* passes the that widget's window ID to the other process, which then
* creates a Gtk::Plug with that window ID. Any widgets contained in the
* Gtk::Plug then will appear inside the first applications window.
*
* The socket's window ID is obtained by using get_id(). Before using this
* function, the socket must have been realized, and for hence, have been
* added to its parent.
*
* @code
* Gtk::Socket socket;
* parent.add(socket);
*
* // The following call is only necessary if one of the ancestors of the
* // socket is not yet visible
* socket.realize();
*
* cout << "The ID of the sockets window is: " << socket.get_id() << endl;
*
* @endcode
*
* Note that if you pass the window ID of the socket to another process that
* will create a plug in the socket, you must make sure that the socket
* widget is not destroyed until that plug is created. Violating this rule
* will cause unpredictable consequences, the most likely consequence being
* that the plug will appear as a separate toplevel window. You can check if
* the plug has been created by examining the plug_window member of the
* GtkSocket structure returned by gobj(). If this field is non-NULL, then
* the plug has been successfully created inside of the socket.
*
* When gtkmm is notified that the embedded window has been destroyed, then
* it will destroy the socket as well. You should always, therefore, be
* prepared for your sockets to be destroyed at any time when the main event
* loop is running.
*
* The communication between a Gtk::Socket and a Gtk::Plug follows the
* XEmbed protocol. This protocol has also been implemented in other
* toolkits, e.g. Qt, allowing the same level of integration when embedding
* a Qt widget in gtkmm or vice versa.
