So the recommended way to do it is just do the following (in pseudo code)
do {
response = gtk_dialog_run (....)
} while (response == OK && !validated )
I thought of using this but it did not really seem like an elegant way
to do it. I was thinking that there might be some signal handler which
could do the checking and that gtk_dialog_run would only return if OK
was pressed and the data was valid
