Hello there,
Here is a collection of text-list related problems I have gotten so
far:
1. how do I set the slider to the 'correct' position on a rebuild ?
2. is there a way to disable multi-selection of items in the list ?
3. how do I get rid of the white area below the last entry ?
see the example for solutions on how to keep the previous
item selection, and to have the same visible items in the list after
the rebuild.

tl: text-list 100x140 data list-block [
if not none? tl/picked [ print first tl/picked ]

button "Rebuild" [
old-picked: tl/picked ; save old selection
old-sn: tl/sn ; save old visible area
build-layout ; rebuild
tl/picked: old-picked ; initial selection is what was before
tl/sn: old-sn ; make what was visible before visible again
; how do I set the slider to the same position as before, or to match the tl/sn value ?
