    The preferred usage in GTK 2.0 for modal dialogs is to
    do gtk_dialog_run(). The buttons all emit a response
    code when they're pressed. Escape emits a "cancel"
    type signal.

    This is the normal way things are done in GTK 2.x. I
    made a convenience method to set the window's parent,
    connect it to its help page, set the default button
    and widget, etc...

    The only time I'd see the "OK" button getting disabled
    is when 'To' is greater than 'From' or if the # of
    copies is 0. Then again, I might set up the UI so that
    those choices could never be entered. Feel free to
    make such a change. I personally advocate using the
    Gnome build and the GnomePrintDialog.
