You can view hierarchy of classes, interfaces, and types in the Class Explorer.
To show the tree of classes, interfaces, and types hierarchy
- Open the Delphi Class Explorer window by choosing ViewDelphi Class Explorer.
- Place the cursor inside the Class Viewer pane (the top area of the Class Explorer window). Click a node in the tree showing classes, interfaces, types, and namespaces declared in your project. Initially the tree displays only the one level of the most parent classes/interfaces declared in your project; therefore, all nodes are collapsed and the icons are displayed before them.
- Click a tree node to expand it. Sub-tree growing from the node will appear. Also the Member List pane will display members declared in this node.
