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.

do this in main

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. "
