Node Image

• Aug 01, 2018

Nodes can display two images.

• Select Image - Typically indicates the node selection (focus) state. However, the same select image can be displayed for a node regardless of the node state. The TreeList provides a mechanism to automatically substitute a select image when a node receives/loses focus.
• State Image - Typically indicates any state of a node.

If both select and state images are specified, the select image is displayed first.

The table below lists the main properties affecting element appearance.
