20 \ingroup gpad
21 
22 A TPaveLabel specialized to process classes inside a TClassTree.
23 A TPaveClass object is used by the TClassTree to represent a class.
24 A TPaveClass has the same graphical representation as a TPaveLabel.
25 
26 Using the context menu on can select additional options in the ClassTree:
27  - Show classes using this class
28  - Show all classes used by this class
