Description
This section describes the use of the object SimpleSwatTreeGrid, a possibility to show and work on nested (recursive) data structures.
Some theoretical introduction: The TreeGrid is a complex object type, which combines the nested structure of a tree and the display of multiple columns per entry, which is provided by a grid. To enable such Tree-Structures (which means parent-child-relations), B1 provides a generic datamodel, named Struct-Tables, which hold the relation information (by using the selfHdl). The needed logic (which data should be displayed, which types can have relations) can be achieved by configurations and some mapping in OE Code.

Attributes
attribute | description | Example/Values |
SUBTYPE | Defines, how the TreeGrid will be rendered | - SKIP_LISTBAR: will render only the treegrid and posframe
- TREE-ONLY: will only render the treegrid itself (no listbar, no posframe) |
