We have implemented menus, a toolbar and a main widget (a TQWidgetStack). We've also created signal and slot connections and implemented many custom slots. In the following chapter we will complete the application by implementing custom dialogs, and by making use of common dialogs where appropriate.</p> <!-- eof --> |
