SAP Tree is a control that allows you to display tree structures on a screen. It has been developed by SAP, and while it fulfills the basic requirements of a tree control, it has not been adapted for individual applications.
The SAP system contains the following example programs: SAPCOLUMN_TREE_CONTROL_DEMO, SAPSIMPLE_TREE_CONTROL_DEMO, and SAPTLIST_TREE_CONTROL_DEMO.

List structure: Each node may have more than one entry. The entries are displayed from left to right.
Column structure: Tree structure with freely-definable columns.
