Use the Multi-Class Hierarchy Window or the Single-Class Hierarchy Window to analyze inheritance in your source code. Look for the small triangle to the left of a class name, as shown in Figure 7.7. This triangle indicates that the class has multiple ancestors. Use the associated Ancestor Class pop-up menu to jump to any ancestor class to study its descendants (or ancestors). Use the Hierarchy expansion triangle to expose or conceal subclasses.
