Control tab focus (choose next element to focus) with GTK / PyGTK

How can I force the Tab to focus the element I want, is it possible to give my software a list of elements to c开发者_如何学运维ycle focus ?

I remember once using a property called tabindex, but I can't find it anymore.

Yes, you can set the order of focusing for each widget in a container, using the function container.set_focus_chain().
