gtk - GTKSocket, widget, and glade -

-

i have following code:

    builder = gtk.builder()     builder.add_from_file(glade_file)     builder.get_object("windowmain").show()     socket = gtk.socket()     socket.add_id(long(openglwindowid))     builder.get_object('alignment1').add(socket)

where alignment1 gtkalignment widget. when run this, get:

fubar.py:64: gtkwarning: ia__gtk_socket_add_id: assertion `gtk_widget_anchored (socket)' failed   socket.add_id(long(self.openglwindowid))

does know widget should use gtk.socket() when building glade file? have mis-understood vital?

i think need add socket alignment before call add_id() method.
