[REBOL] Re: How to create different context in View?
From: ale870:gmai:l at: 25-Jul-2007 18:26
Hello,
based on the following code:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
rebol []
t: make object! [
myValue: "Z"
getValue: does [ myValue ]
t1: none
f: bind [ t1: button "Show value" [t1/text: getValue show t1] ] 'self
]
a: make t [myValue: "A"]
b: make t [myValue: "B"]
l: layout [
button "Alert <A>" [prin "Valore A: " a/myValue: input]
button "Alert <B>" [prin "Valore B: " b/myValue: input]
pa: box 300x100
pb: box 300x100
]
pa/pane: layout a/f
pb/pane: layout b/f
view l
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Is there any way to dynamically create in context variables (t1) based on
the contents of f?
Why final target is creating vars like t1 with a function, so the final user
does not need to make them one by one.
(as soon as I finished, I will post my final project, almost completed,
called "Laccio". It is a toolkit to create a system to make "components"
reusable, standardized, and based on MVC modelling).
Thank you!
