I have some dialogs of this sort in my app. For these I don't use gtk_dialog_run(). I construct a dialog widget and let it just "sit there" until it is explicitly destroyed. I have a callback attached to the Enter key and/or an OK button. This callback checks the validity of the dialog data and * if the user input is OK, destroys the dialog and calls the next task; but * if the input is not OK, leaves the dialog open, and superimposes a modal dialog (with a single OK or Dismiss button) saying that the input was invalid. Closing this latter dialog leaves the original dialog as the focused widget. If you follow this model, it's a nice courtesy to offer the user a way out: a Cancel button in the original dialog, which allows them to say, "The heck with this 'invalid input', I'm out of here."
