[REBOL] R: Dynamic Layout creation
From: riusa:email:it at: 16-Mar-2002 0:15
furthermore, about my previous question, I "discovered" another thing:
if I type, from console:
>> A: "b1: button {prova}"
== "b1: button {prova}"
then:
>> la: to-block a
== [b1: button "prova"]
now if I try to make a layout:
>> view layout la
** Script Error: b1 is not defined in this context
** Where: forever
** Near: set :var new new/var: to-word
but if I directly type the block (not write in string then convert):
>> lb: [b1: button "prova"]
== [b1: button "prova"]
>> view layout lb
It works! WHY?! "la" and "lb" seem the same! where is the difference?
where is my mistake?
thanks a lot!
bye!

Oggetto: [REBOL] Dynamic Layout creation
After some tests, I discovered I could create a block (dinamically, at
runtime) and use this to create a layout.
For example: if I want to create some radio buttons at runtime (I'm
reading some records in a database, and every record generates a radio
button), I can create a block and...
==================================
myBlock: [backcolor gray across]
append myBlock [radio label "test"]
view layout myBlock
==================================
the previous code functions. But how can I do to assign a different
variable to every radio-button (see the hypotetical result below):
var1: radio label "test 1" return
var2: radio label "test 2" return
var3: radio label "test 3" return
I cannot create var...
Can someone help me?
Thanks! bye!
