The following script may be of use to those requiring a simple way of
managing a text-list. Note that the (tab) method may not be appropriate for
more complex data structures (especially if column widths vary greatly),
but I have found this works well for key / value pairs where the key is a
number / code or date of fairly consistent length.
<code>
REBOL []
change svv/vid-styles/text-list/init/75/4/6 'gold
stylize/master [slider: scroller]
record-list: copy []
repeat cnt 20 [insert record-list reform [cnt "^-" now/date]]
modify-list: func [face /update-row row-to-update /add-row row-to-add] [
either update-row [
replace face/data face/picked/1 row-to-update
][
either add-row [
insert face/data row-to-add
][
remove find face/data face/picked/1
]
face/sld/data: 0
face/sn: 0
face/sld/redrag face/lc / max 1 length? head face/lines
]
show face
]
view layout [
lst: text-list data record-list as-is
across
btn "Update" [modify-list/update-row lst reform [random 100 "^-" now/time]]
btn "Add" [modify-list/add-row lst reform [random 100 "^-" now/time]]
btn "Delete" [modify-list lst]
]
</code>
