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. 92 */ 93 public class Socket : Container 94 { 95 /** the main Gtk struct */ 96 protected GtkSocket* gtkSocket; 97 98 /** Get the main Gtk struct */ 99 public GtkSocket* getSocketStruct() 100 { 101 return gtkSocket; 102 } 103 104 /** the main Gtk struct as a void* */ 105 protected override void* getStruct() 106 { 107 return cast(void*)gtkSocket; 108 } 109 110 protected override void setStruct(GObject* obj) 111 { 112 gtkSocket = cast(GtkSocket*)obj; 113 super.setStruct(obj); 114 } 115 116 /** 117 * Sets our main struct and passes it to the parent class. 118 */ 119 public this (GtkSocket* gtkSocket, bool ownedRef = false) 120 { 121 this.gtkSocket = gtkSocket; 122 super(cast(GtkContainer*)gtkSocket, ownedRef); 123 } 124 125 /** 126 */ 127 128 public static GType getType() 129 { 130 return gtk_socket_get_type(); 131 } 132 133 /** 134 * Create a new empty #GtkSocket. 135 * 136 * Return: the new #GtkSocket. 137 * 138 * Throws: ConstructionException GTK+ fails to create the object. 139 */ 140 public this() 141 { 142 auto p = gtk_socket_new(); 143 144 if(p is null) 145 { 146 throw new ConstructionException("null returned by new"); 147 } 148 149 this(cast(GtkSocket*) p); 150 } 151 152 /** 153 * Adds an XEMBED client, such as a #GtkPlug, to the #GtkSocket.
