They will often fail with g_critical() or g_warning(), but 87 * this must not be relied on. 88 * 89 * Users of objects implementing this are not intended to use 90 * the interface method directly, instead it will be used automatically 91 * in various ways. For C applications you generally just call 92 * g_initable_new() directly, or indirectly via a foo_thing_new() wrapper. 93 * This will call g_initable_init() under the cover, returning NULL and 94 * setting a GError on failure (at which point the instance is 95 * unreferenced). 96 * 97 * For bindings in languages where the native constructor supports 98 * exceptions the binding could check for objects implemention GInitable 99 * during normal construction and automatically initialize them, throwing 100 * an exception on failure. 101 */ 102 public template InitableT(TStruct) 103 { 104 105 /** the main Gtk struct */ 106 protected GInitable* gInitable; 107 108 109 /** Get the main Gtk struct */ 110 public GInitable* getInitableTStruct() 111 { 112 return cast(GInitable*)getStruct(); 113 } 114 115 116 /** 117 */ 118 119 /** 120 * Initializes the object implementing the interface. 121 * The object must be initialized before any real use after initial 122 * construction, either with this function or g_async_initable_init_async(). 123 * Implementations may also support cancellation.
