I read your message three times and finally gave up - not understanding
your problem ...

No, it nearly does as you requested. But since I wanted the creation code
to not fire any signals (most people would not love that) I connected last.
A solution would be to mark the widget as hidden (not shown) and call show
in _your_ custom ctor. Should work well.
I was not aware that there was _any_ reasonable reason to swap connect and
show. And I'm still not convinced it would work well in other cases.
## Can someone on the gtkmm mailing list convince me? E.g are there some
signals which would qualify as creation only signals.

Not yet. I'm planning to ask the ximian people - or register a
BerliOS/SourceForge project if they don't cooperate well enough. Since
glade--'s cvs is hosted by gnome.org ... they would be the first to ask.
