A Graph Window opens displaying the inheritance relationship of the class ATwinkleTimeHandler. The status bar above the Graph Window contents shows you which object-action pair was used to create the currently displayed view. In this case, the object was the class ATwinkleTimeHandler and the action was Graph All Base Classes. When an option is not available for a given program element, the menu item will be disabled. There is a list to the right of the graph which alphabetically lists all the objects currently displayed in the graph.
