I where not exactly able to solve the problem, but I may have understood
something more: the problem is that the action_area is a gtk.HBox, but
it seems it doesn't behave as a HBox in the fact that it doesn't take
care of the "homogeneous" property. Since the text field you add is 160
pixels wide, every other widget in the action_area takes up the same
space, and hence the window is huge.
Take a look at the attachment: I just stopped using the action_area and
added a new HBox, and it works. If instead you uncomment the
"set_homogeneous(True)" call, the problem is here again.
Now: I realize this is not a solution, and if I made no mistakes you may
also want to file a bug about that HBox not behaving like a HBox;
however, about your problem, my advice is that you're using the action
area - and, in general, the Dialog object - in a way that it is not
intended to be used: usually a dialog is really a lot of stuff, and some
_buttons_ in the bottom of the window (the action_area), so if I was in
you I would:
- just use a gtk.Window, or
- just move those controls, which are atypical for an action_area, in
other parts of the dialog.
