Mike, I think you are just killing the algorithms for layout management
by mixing GtkTable and GtkHBox ;) Or maybe it will require refinement
on the layout constraints.
I propose a simpler approch with GtkScrolledWindow :
< t = gtk.GtkHBox ()
< table = gtk.GtkTable (2, 1)
< t.add (table)
< text = gtk.GtkText ()
< text.set_usize (-1, 150)
< table.attach (text, 0, 1, 0, 1)
< scroll = gtk.GtkVScrollbar (text.get_vadjustment ())
< table.attach (scroll, 1, 2, 0, 1, xoptions=gtk.FILL)

If you need to access the scrollbar you'll need to add this :
> scroll = t.vscrollbar
BUT, I noticed that there is a bug in GtkScrolledWindow on
accessing vscrollbar attribute, import the following path
file :
----------------------------------------------------------------
patch.py
----------------------------------------------------------------
# BUG in 0.6.8 : GtkScrollWindow : has_attrs -> has_key
import gtk
from gtk import _obj2inst
import _gtk
def patch(self, attr):
attrs = {
'hscrollbar': _gtk.gtk_scrolled_window_get_hscrollbar,
'vscrollbar': _gtk.gtk_scrolled_window_get_vscrollbar
}
if attrs.has_key(attr):
return _obj2inst(attrs[attr](self._o))
else:
return GtkBin.__getattr__(self, attr)
gtk.GtkScrolledWindow.__getattr__ = patch
del patch
# end bug
----------------------------------------------------------------
