Hi Andrew,
Here's a modified example of one of Jeff Kreis tables to include check box
functionality:
context [
;- The database
tdata: [
["Adamson" "Sarah" 0]
["Adamson" "John" 1]
["Battey" "Nora" 0]
["Roberts" "Julia" 1]
["Spencer" "Frank" 1]
]
;- For the scroll bar
cnt: 0
view layout [
across
space 0
tbl: list 220x400 [across space 0 text 100 text 100 check [tmp:
(face/parent-face/offset/y / face/parent-face/size/y) + 1 if tmp <= length?
tdata [tdata/:tmp/3: either tdata/:tmp/3 = 1[0][1]]]]
supply [
count: count + cnt
face/color: ivory
face/text: none
if even? count [face/color: ivory - 50.50.50]
face/data: false
if none? v: pick tdata count [exit]
switch/default face/style [
check [
face/data: to-logic (pick v index)
]
][face/text: pick v index]
]
sld: slider 16x400 [
c: max 0 to-integer (length? tdata) * value
if c <> cnt [cnt: c show tbl]
] return
]
]
Regards,
James.
