The lines in a text-list are held in a block called data, so...
view layout [
button "Add Line" [
append t/data to-string random 10000
button "Clear" [
; Sort example added while I'm at it...
button "Sort" [
sort/compare t/data func [a b][(to-integer a) < to-integer b]
(Note you can cut and paste that layout directly into the View Console
to test it, just in case you've not discovered this feature yet.)
to check how many items are in the above list.
There are of course ways to update the scroll-bar, but I can't
remember the current best method, (it's been improved with the beta
versions I think), so someone else would be best to explain that.
Hope that helps.
