The thing I want to show today, is enhancing the little application with a toolbar, so let's dig into this...

(Most of the applications which have menus, also have a toolbar. And it is realy easy to set up.)

The nice thing, all toolbar entries should be connected to an existing callback-method in our application, which is reachable already by an menu-entry. A toolbar is only a shortcut to an entry in the menu. So, we only have to design the user-interface, no additional business-logic is needed.
