Thank you Lex!
It had also crossed my mind to move the validation to the main app, but of some reason I thought it would be neater to have it where it actually should be taken care of. But your solution will work perfectly ok, and actually also, when I think about it, look quite nice.
So, once again, thank you! And thank you for pointing things out about the delete-event. :o)
Best regards,
Paul

Suggest you do the validation here and if it fails, show the fail
message then loop back to dlg.run to give them another go, note you
haven't hidden the dialog yet so the user won't see any change.
Go on to hide and destroy the dialog when the UP is correct or give up.

As documented, delete isn't emitted on dialogs:
"If a dialog receives a delete event, the "response" signal will be
emitted with a response ID of GTK_RESPONSE_DELETE_EVENT. "
