Class hierarchy of an individual class

So far we've looked at an overview of the complete class hierarchy. Let's now take a look at the superclasses and subclasses of an individual class. To see the superclasses and subclasses (i.e. only the immediate relatives) of class

Button :

Right-click anywhere in the Project Tree.

Right-click in the Hierarchy view and choose
Context menu > Show Button Relatives
