This is getting a little off-topic, but I'm doing similar things. I
assume you are using GtkAda (not some other language binding :).

I also have a Clist inside a Scrolled_Window (so I can scroll the list
when it is too big). I did nothing to specify a minimum size; it seems
to request enough to show one line.

You should talk in terms of lines (of information), not pixels. The
user may change their default font to something much larger, in which
case your pixel size will be wrong.

Do you want the minimum size to be more than one line?

If the number was lines of information, I agree that would be useful.
There may be a way to do this with Gtk; I'm still new.
