Release 10.1A: OpenEdge Development:
Progress Dynamics Advanced Development

TreeView

The TreeView pane on the left side of the window displays the class hierarchy of the class objects currently defined in the Repository. Each level (node) in the hierarchy displays the node and the class name. There are three top-level nodes: Base, Progress Dynamics object, and Progress Widget. Beneath each of these nodes there is an Attribute node, a Supported Links node, and a UI Events node. If you customize a class, the customized class appears in the hierarchy with its custom name and a custom icon.

When you select a top-level node from the TreeView, information about the class displays in the maintenance pane tabs to the right. From these tabs, you can maintain information about each class node. To expand a node, click on the plus (+) sign next to the node or double-click the node. To collapse a node, click the minus sign (–) next to the node or double-click the node.
