ObjectClassRef

public struct ObjectClassRef : ObjectClassProtocol

The ObjectClassRef type acts as a lightweight Swift reference to an underlying GObjectClass instance. It exposes methods that can operate on this data type through ObjectClassProtocol conformance. Use ObjectClassRef only as an unowned reference to an existing GObjectClass instance.

The class structure for the GObject type.

(C Language Example):

// Example of implementing a singleton using a constructor.
static MySingleton *the_singleton = NULL;

static GObject*
my_singleton_constructor (GType                  type,
                          guint                  n_construct_params,
                          GObjectConstructParam *construct_params)
{
  GObject *object;

  if (!the_singleton)
    {
      object = G_OBJECT_CLASS (parent_class)->constructor (type,
                                                           n_construct_params,
                                                           construct_params);
      the_singleton = MY_SINGLETON (object);
    }
  else
    object = g_object_ref (G_OBJECT (the_singleton));

  return object;
}
  • ptr
    Untyped pointer to the underlying `GObjectClass` instance.
    

    For type-safe access, use the generated, typed pointer _ptr property instead.
