KXmlGuiWindow provides a full main window view with menubars, toolbars, a statusbar and a main area in the centre for a large widget. For example, the help-menu is predefined. Most KDE applications will derive from this class as it provides an easy way to define menu and toolbar layouts through XML files (this technology is called XMLGUI and is part of the KF5::XmlGui framework). While we will not be using XMLGUI in this tutorial, we will use it in the next.
