module Graphics.UI.Gtk.Embedding.Plug (
-- * Detail
--
-- | Together with 'Socket', 'Plug' provides the ability to embed widgets from
-- one process into another process in a fashion that is transparent to the
-- user. One process creates a 'Socket' widget and, passes the ID of that
-- widgets window to the other process, which then creates a 'Plug' with that
-- window ID. Any widgets contained in the 'Plug' then will appear inside the
-- first applications window.

-- | Creates a new plug widget inside the 'Socket' identified by @socketId@.
-- If @socketId@ is @Nothing@, the plug is left \"unplugged\" and can later be
-- plugged into a 'Socket' by 'Graphics.UI.Gtk.Embedding.Socket.socketAddId'.
--
-- If a NativeWindowId is supplied the foreign application window will
-- immediatly appear in this 'Plug' once it is shown. If @Nothing@ is passed
-- then a 'NativeWindowId' can be extracted from this 'Plug' using 'plugGetId'
-- and be passed to the application which is to be embedded.
