Methods
-------

.. rst-class:: interim-class

.. class:: WebProcessExtension
   :no-index:


   .. method:: get_page(page_id: int) -> ~gi.repository.WebKitWebProcessExtension.WebPage

      Get the web page of the given ``page_id``.



      .. versionadded:: 2.40





      :param page_id: the identifier of the :obj:`~gi.repository.WebKitWebProcessExtension.WebPage` to get





   .. method:: send_message_to_context(message: ~gi.repository.WebKit.UserMessage, cancellable: ~gi.repository.Gio.Cancellable | None = None, callback: ~typing.Callable[[...], None] | None = None, *user_data: ~typing.Any) -> None

      Send ``message`` to the ``WebKitWebContext`` corresponding to ``extension``. If ``message`` is floating, it's consumed.

      If you don't expect any reply, or you simply want to ignore it, you can pass :const:`None` as ``calback``.
      When the operation is finished, ``callback`` will be called. You can then call
      :func:`~gi.repository.WebKitWebProcessExtension.WebProcessExtension.send_message_to_context_finish` to get the message reply.



      .. versionadded:: 2.40





      :param message: a :obj:`~gi.repository.WebKitWebProcessExtension.UserMessage`


      :param cancellable: a :obj:`~gi.repository.Gio.Cancellable` or :const:`None` to ignore


      :param callback: A :obj:`~gi.repository.Gio.AsyncReadyCallback` to call when the request is satisfied or :const:`None`


      :param user_data: the data to pass to callback function





   .. method:: send_message_to_context_finish(result: ~gi.repository.Gio.AsyncResult) -> ~gi.repository.WebKit.UserMessage

      Finish an asynchronous operation started with :func:`~gi.repository.WebKitWebProcessExtension.WebProcessExtension.send_message_to_context`.



      .. versionadded:: 2.40





      :param result: a :obj:`~gi.repository.Gio.AsyncResult`











Signals
-------

.. rst-class:: interim-class

.. class:: WebProcessExtension.signals
   :no-index:
   

   .. method:: page_created(web_page: ~gi.repository.WebKitWebProcessExtension.WebPage) -> None

      This signal is emitted when a new :obj:`~gi.repository.WebKitWebProcessExtension.WebPage` is created in
      the Web Process.



      .. versionadded:: 2.40





      :param web_page: the :obj:`~gi.repository.WebKitWebProcessExtension.WebPage` created





   .. method:: user_message_received(message: ~gi.repository.WebKit.UserMessage) -> None

      This signal is emitted when a :obj:`~gi.repository.WebKitWebProcessExtension.UserMessage` is received from the
      ``WebKitWebContext`` corresponding to ``extension``. Messages sent by ``WebKitWebContext``
      are always broadcasted to all web extensions and they can't be
      replied to. Calling :func:`~gi.repository.WebKitWebProcessExtension.UserMessage.send_reply` will do nothing.



      .. versionadded:: 2.40





      :param message: the :obj:`~gi.repository.WebKitWebProcessExtension.UserMessage` received
