A tree graphic is a graphic that displays objects in a tree structure.

The tree control is an ActiveX control that fulfills the basic requirements of a tree control but is not tailored to the needs of individual applications.

The tree control can be implemented in three different ways:

• Simple tree structure: A simple tree structure with the nodes arranged in a single column
• List structure: A tree with nodes that have several items. The items are displayed from left to right
• Column structure: A tree structure with freely-definable columns
