face/lines provides an index to which line in the list has just been
clicked on, so that can be used as a pointer to your data. There's
also a face/user-data which could be used to store your values.
Using this approach, you could have something like this...
REBOL []
my-labels: [
"ten"
"eleven"
"twelve"
"thirteen"
"fourteen"
"fifteen"
"sixteen"
"seventeen"
"eighteen"
"nineteen"
]
my-data: [10 11 12 13 14 15 [this is number 16] 17 18 19]
view layout [
text-list 200x70 data my-labels user-data my-data [
probe pick face/user-data index? face/lines
]
]
(The [this is number 16] is just to show you you could have any data
you like in my-data.)
HTHs.
