Yes. I considered that earlier, but thought I might ask first in case 
there was an even simpler way...

Anyhow, I've now tried this, and it nearly looks the way I want, but 
there is one problem: The message dialog will also contain an icon 
indicating the message type. I don't want that, but I can't seem to find 
a way to disable it.

Possibly a dumb question, but how exactly can I do that? I thought that 
it would go away if I did

msgBox.clear();

after creating as

Glib::RefPtr<Gtk::MessageDialog> msgBox=new Gtk::MessageDialog(*this, 
msg, Gtk::MESSAGE_INFO, Gtk::BUTTONS_NONE);

but it doesn't.
