I may be wrong, but to me it looks the logic is much simpler than what you expect. You expect a left alignment, but there is no reason why it should be. If I understand correctly, "pack_start" and "pack_end" refer to the _order_ of widgets, and not to any alignment of the widgets as a whole. So if there is no left/right alignment rule, the default is just to distribute them on all the available space, leaving the same empty space among them or, if you instead set "homogeneous", allocating to each the same space, which will then possibly be partly empty. Your logic could make sense, it is just based on more assumptions. > [...] > What I would expect : > ------------------- > > 2.a/ > homogeneous = True > expand = False > fill = whatever > -> Objects would be of the same size : the size of the largest one, and they > would be left-aligned (pack_start() being used). > > [| a ||abc|| | ] > > [...] > > This seems more logical to me.

I anticipate that your reaction will be "but those are ugly hacks", and I guess - but again, I might be wrong - the answer of the developers would be "what you're trying to do is ugly". bye Pietro _______________________________________________ pygtk mailing list [email protected] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
