Thanks for responding Henry.
I did try that property when I found no hover capability on the Tree widget. I
set the widget to read-only and scripted...
on actionInspect pPath
put the arrayData of widget "Tree" into aContent
replace comma with "][" in pPath
answer aContent & "[" & pPath & "]"
end actionInspect
…however, like the highlightedElement property, this still returns the
element’s key rather than its content, despite my feeble attempts at
post-processing.
Hence the second part of my question which reveals my lack of array syntax
knowledge! :)
Best,
Keith
