How to create different context in View?

 [1/9] from: ale870::gmail::com at: 24-Jul-2007 7:35


Hello, I have a problem (my friends say that I have a lot of problems... :-( ). Can I create a Rebol/View form, separating the contexts inside? What I want to do, is something like this: view layout [ context1 [ f: field ] context2 [ f: field ] button [ alert context1/f/text alert context2/f/text ] ] Is it feasible? I need to refer the same variable name, insulating it. Obviously, in the previous case, the system renders either context1 or context2. Final output, when program starts, could be something like: |==== field in context1 =====| |==== field in context2 =====| |== button ==| Thank you! -- --Alessandro

Hi Alessandro,
> Can I create a Rebol/View form, separating the contexts inside? >
Yes, you can do so, although it's somewhat cumbersome: ------------------------------------------------------------------------ rebol [] foo: context [field: none] bar: context [field: none] output: does [print ["foo/field:" foo/field/text tab "bar/field:" bar/field/text]] view layout probe compose [ across label "foo/field:" (bind [field:] in foo 'self) field [output] return label "bar/field:" (bind [field:] in bar 'self) field [output] ] ------------------------------------------------------------------------ HTH, Christian

Hi, Anton Rolls came up with this for a RebGUI question I had oneset: context [field: none] twoset: context [field: none] ; Anton's magic to set-word! trick view layout compose [ =C2=A0 =C2=A0 (to set-word! in oneset 'field) field =C2=A0 =C2=A0 (to set-word! in twoset 'field) field =C2=A0 =C2=A0 btn "Show the fields" [alert oneset/field/text =C2=A0alert twoset/field/text] ] On Tuesday 24 July 2007 15:58, Christian Ensel wrote:

hi, my god... why is everyone trying to do strange tricks! even composing a block to get to your ends!!! has everyone forgotten why the do word is defined within VID's dialect? this is THE real solution ;-) rebol [] view layout [ fld: field do [fld_a: context [value: fld]] fld: field do [fld_b: context [value: fld]] button [ print fld_a/value/text print fld_b/value/text ] ] -MAx On 7/24/07, Alessandro Manotti <ale870-gmail.com> wrote:

Maxim; I like your sequence (and thanks for that), but I'm sticking with the trick Anton clued me into. :) It allows for creation of RebGUI and View apps with ONE exposed global name, a master object. Make it an un set-word'ed context and a gui app with full cross field checks and balances, linked scrollers et al, can be made that exposes ZERO namespace entries. The (to set-word! in object 'member) is staying in my bag of tricks. It allows for some pretty powerful object based gui building with the added bonus of not littering. Christian; I like your solution too. A nice exercise in bindology. I learned something by reading it. Cheers, Brian On Tuesday 24 July 2007 21:15, Maxim Olivier-Adlhoch wrote:

Hello, first of all: thank you for everybody. I learned a lot of tips & tricks!!!!! I created a "final " solution for my needs (I will use it). This is the (working) code: t: make object! [ myValue: "Z" getValue: does [ myValue ] t1: none f: bind [ t1: button "Show value" [t1/text: getValue show t1] ] 'self ] l: layout [ do [ a: make t [myValue: "A"] ] do [ b: make t [myValue: "B"] ] 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 I hope this could help someone.

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).

I will do like this: make-panel: func [a /local obj][ obj: construct append cp [panel: none] a obj/panel: bind/copy a in obj 'self obj ] a: make-panel [t1: field 100 [print t1/text]] b: make-panel [t1: field 100 [print t1/text]] view layout [ panel a/panel panel b/panel btn "a" [print a/t1/text] btn "b" [print b/t1/text] ]

hehe, after 7-8 years of doing rebol, I learn there is a panel style in VID ! just funny how some little things slip past our conscience. :-) -MAx On 7/25/07, Steeve ANTOINE <sant4-wanadoo.fr> wrote:
