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, e.g. Qt, 83 * allowing the same level of integration when embedding a Qt widget 84 * in GTK or vice versa. 85 * 86 * The #GtkPlug and #GtkSocket widgets are only available when GTK+ 87 * is compiled for the X11 platform and %GDK_WINDOWING_X11 is defined. 88 * They can only be used on a #GdkX11Display. To use #GtkPlug and 89 * #GtkSocket, you need to include the `gtk/gtkx.h` header. 90 */ 91 public class Socket : Container 92 { 93 /** the main Gtk struct */ 94 protected GtkSocket* gtkSocket; 95 96 /** Get the main Gtk struct */ 97 public GtkSocket* getSocketStruct() 98 { 99 return gtkSocket; 100 } 101 102 /** the main Gtk struct as a void* */ 103 protected override void* getStruct() 104 { 105 return cast(void*)gtkSocket; 106 } 107 108 protected override void setStruct(GObject* obj) 109 { 110 gtkSocket = cast(GtkSocket*)obj; 111 super.setStruct(obj); 112 } 113 114 /** 115 * Sets our main struct and passes it to the parent class. 116 */ 117 public this (GtkSocket* gtkSocket, bool ownedRef = false) 118 { 119 this.gtkSocket = gtkSocket; 120 super(cast(GtkContainer*)gtkSocket, ownedRef); 121 } 122 123 124 /** */ 125 public static GType getType() 126 { 127 return gtk_socket_get_type(); 128 } 129 130 /** 131 * Create a new empty #GtkSocket. 132 * 133 * Return: the new #GtkSocket. 134 * 135 * Throws: ConstructionException GTK+ fails to create the object. 136 */ 137 public this() 138 { 139 auto p = gtk_socket_new(); 140 141 if(p is null) 142 { 143 throw new ConstructionException("null returned by new"); 144 } 145 146 this(cast(GtkSocket*) p); 147 } 148 149 /** 150 * Adds an XEMBED client, such as a #GtkPlug, to the #GtkSocket.
