[REBOL] list: multiple columns update
From: robert::muench::robertmuench::de at: 13-Feb-2002 21:00
Hi, I'm trying to use a list with at least two columns and have the following
supply function in use:
_supply: [
; do we have enough data?
if count > length? project-list [face/show?: false exit]
face/show?: true
; get project
current-project: pick project-list count
; add stripes look to the list
face/color: ivory
if even? count [face/color: ivory - 50.50.50]
; change color if project is selected
### if current-project/selected [face/color: yellow]
; we use the current index to pick the entry from our object to display
; first current-project gives the list of fields in the object
; +1 skips the self reference
field: pick first current-project index + 1
face/text: current-project/:field
; store the project index into the predefined user-data field of the face,
; so that we can later access it
face/user-data: count
]
The line marked with ### should set the color of each column to yellow but only
the first column is displayed with a yellow background color. The other columns
change the color as soon as I click on the face. Why aren't the other faces
color get updated too?
