39  * Together with #GtkPlug, #GtkSocket provides the ability to embed
40  * widgets from one process into another process in a fashion that
41  * is transparent to the user. One process creates a #GtkSocket widget
42  * and passes that widget’s window ID to the other process, which then
43  * creates a #GtkPlug with that window ID. Any widgets contained in the
44  * #GtkPlug then will appear inside the first application’s window.
45  * 
46  * The socket’s window ID is obtained by using gtk_socket_get_id().
47  * Before using this function, the socket must have been realized,
48  * and for hence, have been added to its parent.
49  * 
50  * ## Obtaining the window ID of a socket.
51  * 
52  * |[<!-- language="C" -->
53  * GtkWidget *socket = gtk_socket_new ();
54  * gtk_widget_show (socket);
55  * gtk_container_add (GTK_CONTAINER (parent), socket);
56  * 
57  * // The following call is only necessary if one of
58  * // the ancestors of the socket is not yet visible.
59  * gtk_widget_realize (socket);
60  * g_print ("The ID of the sockets window is %#x\n",
61  * gtk_socket_get_id (socket));
62  * ]|
63  * 
64  * Note that if you pass the window ID of the socket to another
65  * process that will create a plug in the socket, you must make
66  * sure that the socket widget is not destroyed until that plug
67  * is created. Violating this rule will cause unpredictable
68  * consequences, the most likely consequence being that the plug
69  * will appear as a separate toplevel window. You can check if
70  * the plug has been created by using gtk_socket_get_plug_window().
71  * If it returns a non-%NULL value, then the plug has been
72  * successfully created inside of the socket.
73  * 
74  * When GTK+ is notified that the embedded window has been destroyed,
75  * then it will destroy the socket as well. You should always,
76  * therefore, be prepared for your sockets to be destroyed at any
77  * time when the main event loop is running. To prevent this from
78  * happening, you can connect to the #GtkSocket::plug-removed signal.
79  * 
80  * The communication between a #GtkSocket and a #GtkPlug follows the
81  * [XEmbed Protocol](http://www.freedesktop.org/Standards/xembed-spec).
82  * This protocol has also been implemented in other toolkits,
83  * e.g. Qt, allowing the same level of
84  * integration when embedding a Qt widget
85  * in GTK or vice versa.
86  * 
87  * The #GtkPlug and #GtkSocket widgets are only available when GTK+
88  * is compiled for the X11 platform and %GDK_WINDOWING_X11 is defined.
89  * They can only be used on a #GdkX11Display. To use #GtkPlug and
90  * #GtkSocket, you need to include the `gtk/gtkx.h`
91  * header.
