Peas.ObjectModule.register_extension_factory

### Method

# Peas ObjectModuleregister_extension_factory

#### Declaration [src]

    void
    peas_object_module_register_extension_factory (
      PeasObjectModule* module,
      GType exten_type,
      PeasFactoryFunc factory_func,
      gpointer user_data,
      GDestroyNotify destroy_func
    )

#### Description [src]

Register an implementation for an extension type through a factory function `factory_func` which will instantiate the extension when requested.

This method is primarily meant to be used by native bindings (like gtkmm), creating native types which cannot be instantiated correctly using `g_object_new()`. For other uses, you will usually prefer relying on peas_object_module_register_extension_type().

Since libpeas 1.22, `exten_type` can be an Abstract `GType` and not just an Interface `GType`.

#### Parameters

`exten_type`

  Type: `GType`

  The `GType` of the extension you implement.

`factory_func`

  Type: `PeasFactoryFunc`

  The `PeasFactoryFunc` that will create the `exten_type` instance when requested.

`user_data`

  Type: `gpointer`

  Data to pass to `func` calls.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`destroy_func`

  Type: `GDestroyNotify`

  A `GDestroyNotify` for `user_data`.
