Hmm. Here is the comment for Show_All from gtk-widget.ads:

   --  Show Widget and all its children recursively.

So what did you expect?

Apparently you had not done a "show". The default state after Gtk_New
is hidden, so you need to call "show" on all the widgets that needed
to be shown. I guess that's why you did Show_All?

Yep, that's what the documentation says will work.

Well, try using "show" only where you need it, rather than "show_all".

What would be more elegant, in your opinion?
