To graph a class hierarchy:
Choose Browse > Graph Classes, or select a class in the source code or Debugging window and choose Browse > Graph Classes.
Type a class name in the Class text box and click Add Current Class or press Return.
To display information about a class:
Click a node to select it.
Click one of the buttons below the Class Graph pane to display the information you want. The footer of the window displays the number of nodes added and the number of nodes displayed out of the number that exist for the current function.
From the Nodes menu, choose commands for other viewing options such as showing, hiding, expanding, or collapsing nodes (see "Showing or Hiding Nodes").
Select a node and click Show Source to view the source in the editor window.
You can change the display of the Class Graph window using the commands on the Graph menu (see "Changing the Look of a Call or Class Graph"). You can also print the class graph, as described in "Printing a Graph".
