An alternative appears to be to assign the new block to the text-list lines path. This is demonstrated below, as well as, the way to reset the slider for a new list that is longer than the original: view layout [ t1: text-list 100x50 data ["1" "2" "3"] b1: button "click" [ t1/lines: ["a" "b" "c" "d" "e" "f"] ;alternative assignment t1/sld/redrag t1/lc / max 1 length? head t1/lines ;resets slider show t1 ] ] I really don't know if one method of reassigning a text-list is "preferred" or not. Given that the slider is internally set based on /lines, I assume it will be safe from deprecation. The documentation does not address these points to my knowledge. --Scott Jones
