Show Tree widget row contents on hover?

[Keith Clarke]

Thanks Bob for the syntax for setting the widget’s tooltip. That’ll help once I have some sensible data appearing in the answer dialogue box that I can use in the tooltip.

My key problem now is how to translate the comma-delimited path returned by the actionInspect function - pPath - of the form 'Key1,Key2,Key3' …to the correct syntax to have the array return the content of Key3.

My code below converts pPath to LiveCode array key syntax, i.e. [Key1][Key2][Key3] ...and then concatenates this after aContent, the name of the array variable into which the widget’s arrayData has been extracted.

As far as I can tell, this should resolve to... answer aContent[Key1][Key2][Key3] ...which should return the content of Key3 but I’m seeing '[Key1][Key2][Key3]’ in the answer dialogue box.

Any clues?
Best,
Keith
