About Hierarchical Trees

The hierarchical tree displays data in the form of a standard navigator, similar to those used in Oracle Forms.

You can populate a hierarchical tree with values contained in a Record Group or Query Text. At runtime, you can programmatically add, remove, modify, or evaluate elements in a hierarchical tree.

The amount of data displayed at any one time depends upon the expansion of individual data nodes, whether through Built-ins or a user clicking on a node. The data set generally will be initially specified in Oracle Forms, and may be modified or entirely replaced at runtime.
