When a new 40 * connection is made to the service the #GSocketService::incoming 41 * signal is emitted. 42 * 43 * A #GSocketService is a subclass of #GSocketListener and you need 44 * to add the addresses you want to accept connections on with the 45 * #GSocketListener APIs. 46 * 47 * There are two options for implementing a network service based on 48 * #GSocketService. The first is to create the service using 49 * g_socket_service_new() and to connect to the #GSocketService::incoming 50 * signal. The second is to subclass #GSocketService and override the 51 * default signal handler implementation. 52 * 53 * In either case, the handler must immediately return, or else it 54 * will block additional incoming connections from being serviced. 55 * If you are interested in writing connection handlers that contain 56 * blocking code then see #GThreadedSocketService. 57 * 58 * The socket service runs on the main loop of the 59 * [thread-default context][g-main-context-push-thread-default-context] 60 * of the thread it is created in, and is not 61 * threadsafe in general. However, the calls to start and stop the 62 * service are thread-safe so these can be used from threads that 63 * handle incoming clients. 64 * 65 * Since: 2.22 66 */ 67 public class SocketService : SocketListener 68 { 69 /** the main Gtk struct */ 70 protected GSocketService* gSocketService; 71 72 /** Get the main Gtk struct */ 73 public GSocketService* getSocketServiceStruct() 74 { 75 return gSocketService; 76 } 77 78 /** the main Gtk struct as a void* */ 79 protected override void* getStruct() 80 { 81 return cast(void*)gSocketService; 82 } 83 84 protected override void setStruct(GObject* obj) 85 { 86 gSocketService = cast(GSocketService*)obj; 87 super.setStruct(obj); 88 } 89 90 /** 91 * Sets our main struct and passes it to the parent class. 92 */ 93 public this (GSocketService* gSocketService, bool ownedRef = false) 94 { 95 this.gSocketService = gSocketService; 96 super(cast(GSocketListener*)gSocketService, ownedRef); 97 } 98 99 /** 100 */ 101 102 public static GType getType() 103 { 104 return g_socket_service_get_type(); 105 } 106 107 /** 108 * Creates a new #GSocketService with no sockets to listen for. 109 * New listeners can be added with e.g. g_socket_listener_add_address() 110 * or g_socket_listener_add_inet_port(). 111 * 112 * Return: a new #GSocketService. 113 * 114 * Since: 2.22 115 * 116 * Throws: ConstructionException GTK+ fails to create the object. 117 */ 118 public this() 119 { 120 auto p = g_socket_service_new(); 121 122 if(p is null) 123 { 124 throw new ConstructionException("null returned by new"); 125 } 126 127 this(cast(GSocketService*) p, true); 128 } 129 130 /** 131 * Check whether the service is active or not.
