Cannot subclass objects with constructor arguments

[Kerrick Staley <mail kerrickstaley com>]

Hello,
I am having exactly the same issue (when trying to subclass Clutter.Box) as that described in this thread:
http://lists.clutter-project.org/pipermail/clutter-app-devel-list/2011-September/000742.html

Using the workaround that Martin described, I was able to get my code to function, but I'd like to know how to solve this problem in general. If a GObject's .new() method takes arguments, how can you supply those arguments in the __init__() method of a subclass? Here is my code:

from gi.repository import GObject, Clutter
class Editor(Clutter.Box):
    def __init__(self):
        # does not work:      "TypeError: GObject.__init__() takes exactly 0 arguments (1 given)"
        # super(Editor, self).__init__(Clutter.BinLayout.new(4,4))

        
        # also does not work: "TypeError: __init__() takes exactly 1 argument (3 given)"
        # GObject.__init__(self, Clutter.BinLayout.new(4,4))
        
        # workaround
        self.set_layout_manager(Clutter.BinLayout.new(4,4))

Thanks,
