Perl/Tk was certainly an inspiration for the way I set things up.
Though I'd like to keep things simpler - Perl/Tk has gotten better
but it still does a whole bunch of of hash thrashing at startup.

IMHO, my Gtk bindings are at least as OO as Perl/Tk. (Though maybe
not as clever.)

I'm ambivalent about exporting - the only thing you gain is one character
(gtk_init instead of Gtk::init). It would allow making Gtk not a
toplevel module though ...

This really doesn't make sense in the context of gtk - parenting
is a much more flexible thing in gtk than in Tk. In gtk the
only heirarchy the user sees is that of containment - unlike Tk
where there are two non-identical heirarchies - that of
containment/packing and that of ancestry.

Since containment can be expressed in many ways, (item in a list,
widget in a table, widget in a box, etc...), I think it needs
a separate command from creation - which is no worse than Tk
where you have to pack things afterwards.

Thanks for the comments,
