Show Tree widget row contents on hover?

[Keith Clarke]

Hi folks,
I’m experimenting with a tree widget and indentation means that row content gets truncated, so I’m wondering if there is any simple way to show the current row’s content in a tooltip on hover?

The dictionary doesn’t mention any mouse-related messages and the highlightedElement property returns a path as a comma-delimited list of array keys but not the row’s content.

Am I missing some LiveCode magic here that’s too obvious to document?

Thanks in advance.
Keith
