Thanks Brian, Bernd, and everyone else.
When I first saw it (in the form described in Brian's email), I thought
- hmmm, not sure when anyone would use that.
Then I saw an example using split (as described in Bernd's email), and
thought - maybe I can use that some day. :-)
Well - the day has come. I realized that the "Tree View" widget has a
property (hilitedElement) which is the "path" through the array of the
highlighted line - and is the ideal use case for this feature.
And now that I've started using that, I can find *SO* many other uses
My "directory walker" produces an array indexed by folder, then filename
- and the values are some useful info about the file; e.g.
tArray[tFolder][tFilename] === the info I want to keep
I can now put that into a tree view array just by doing
*repeat* foreachkeyK intAflat*
replace*"/"with"/ "intemp* -- trick names to keep folders before
*set the arrayData of widget "Tree" to tA*
