Constructors

   .. classmethod:: new() -> ~gi.repository.Gtk.BuilderCScope

      Creates a new ``GtkBuilderCScope`` object to use with future
      ``GtkBuilder`` instances.

      Calling this function is only necessary if you want to add
      custom callbacks via :obj:`~gi.repository.Gtk.BuilderCScope.add_callback_symbol`.














Methods
-------

.. rst-class:: interim-class

.. class:: BuilderCScope
   :no-index:


   .. method:: add_callback_symbol(callback_name: str, callback_symbol: ~typing.Callable[[], None]) -> None

      Adds the ``callback_symbol`` to the scope of ``builder`` under the
      given ``callback_name``.

      Using this function overrides the behavior of
      :obj:`~gi.repository.Gtk.Builder.create_closure` for any callback symbols that
      are added. Using this method allows for better encapsulation as it
      does not require that callback symbols be declared in the global
      namespace.







      :param callback_name: The name of the callback, as expected in the XML


      :param callback_symbol: The callback pointer
