Hi,
This is how I handle this problem in my scripts...
>> ? layout
USAGE:
LAYOUT specs /size pane-size /offset where /parent new /origin pos /styles list /keep
DESCRIPTION:
Return a face with a pane built from style description dialect.
LAYOUT is a function value.
ARGUMENTS:
specs -- Dialect block of styles, attributes, and layouts (Type: block)
REFINEMENTS:
/size
pane-size -- Size (wide and high) of pane face (Type: pair)
/offset
where -- Offset of pane face (Type: pair)
/parent
new -- Face style for pane (Type: object word block)
/origin
pos -- Set layout origin (Type: pair)
/styles
list -- Block of styles to use (Type: block)
/keep -- Keep style related data
'layout takes a block! as arg, so you can compose the block! _before_ submitting it to
the layoutization.
>> block-layout: [Item1: text "Hi!"]
== [Item1: text "Hi!"]
>> view A: layout block-layout
>> append block-layout [Item2: text "Bye!"]
== [Item1: text "Hi!" Item2: text "Bye!"]
>> view A: layout block-layout
With this approach, you're able to compose dynamically your layouts.
Hope this helps !
