If an object implements this interface the 82 * g_initable_init() function must be called as the first thing 83 * after construction. If g_initable_init() is not called, or if 84 * it returns an error, all further operations on the object 85 * should fail, generally with a G_IO_ERROR_NOT_INITIALIZED error. 86 * Users of objects implementing this are not intended to use 87 * the interface method directly, instead it will be used automatically 88 * in various ways. For C applications you generally just call 89 * g_initable_new() directly, or indirectly via a foo_thing_new() wrapper. 90 * This will call g_initable_init() under the cover, returning NULL and 91 * setting a GError on failure (at which point the instance is 92 * unreferenced). 93 * For bindings in languages where the native constructor supports 94 * exceptions the binding could check for objects implemention GInitable 95 * during normal construction and automatically initialize them, throwing 96 * an exception on failure. 97 */ 98 public template InitableT(TStruct) 99 { 100 101 /** the main Gtk struct */ 102 protected GInitable* gInitable; 103 104 105 public GInitable* getInitableTStruct() 106 { 107 return cast(GInitable*)getStruct(); 108 } 109 110 111 /** 112 */ 113 114 /** 115 * Initializes the object implementing the interface.
