Rich Tree Expand Icon

[Matt Choate]

Is there a way to always have an expand icon on tree nodes? I would like to perform the lookup of child nodes upon a expand and add them to the tree.

[Nick Belaevski]

Yes, check icon* attributes.

[Matt Choate]

icon attributes on the treeNode tag or the tree tag?

[Ilya Shaikovsky]

you could set icons for all the nodes using tree attributes. Or customize for every node using node attributes.
