Andrew,
This sensor use might be what you want.
---Some limitations:
a. applies to the whole window not just the text-list so
you can't have several together
b. does not interact with previous mouse selections.
c. I don't believe it will scroll a list. at least it does not in easyvid.r
when the list of screens gets long.
---Sample
i: 1
show-pick: func [tl direction] [
i: either direction = 'up [i - 1] [i + 1]
i: max 1 min length? tl/data i
tl/picked: compose [(pick tl/data i)]
show tl
]
view layout [
days: text-list 200x140 data ["Monday" "Tuesday" "Wednesday" "Thursday"
"Friday" "Saturday" "Sunday"]
sensor keycode [up left] [show-pick days 'up]
sensor keycode [down right] [show-pick days 'down]
]
