You can also write your layout block on the fly. Anton showed a way to add
created faces (using get-style) into a layout. An alternative is to output
the VID code for the required layout on the fly and then view it.
Although not everyone may "get" this example, it just shows that mixing
REBOL code and data as code is a fun and poweful way to create dynamic
layouts.
e.g..
names: ["John" "Fred" "Bill" "James" "Jenny"]
lay: copy [across]
; a reusable action block
press-action: [
; print the text value from the object next to me
probe get in first next find face/parent-face/pane :face 'text
]
foreach name names [
append lay compose [
button "Choose" press-action
text (name) return
]
]
; to see the VID dialect block we have generated
; probe lay
view layout lay

Tomorrow I will post a demo for using Lists.
