If I could switch it from a text to a label it would be nice. As 
yet I have this puzzling experience:
REBOL []
high-on: high-on-odd: false
swap-even: func [/local n] [

    either high-on [for n 2 8 2 [ panel-rechts/pane/:n/font/color: 'white] 
    high-on: false

    ][              for n 1 7 2 [ panel-rechts/pane/:n/font/color: 'black] 
    high-on: true ]
    show panel-rechts]

swap-odd: func [/local n] [

    either high-on-odd [for n 1 7 2 [panel-rechts/pane/:n/font/color: 
    'white

                                     panel-rechts/pane/:n/style: 'lbl-h-la-white] high-on-odd: false
    ][for n 1 7 2 [panel-rechts/pane/:n/font/color: 'black

                   panel-rechts/pane/:n/style: 'lbl-h-la-normal] high-on-odd: true]
    show panel-rechts]

spiegel-styles: stylize [
    lbl-h-la-normal: text left middle 40x100
    lbl-h-la-white: label left middle 40x100]
    
view layout [styles spiegel-styles
	across
	panel-rechts: panel [below space 0x0

    lbl-h-la-white "_" lbl-h-la-white "_" lbl-h-la-normal "_" lbl-h-la-normal 
    "_"

    lbl-h-la-normal "_" lbl-h-la-normal "_" lbl-h-la-normal "_" lbl-h-la-normal 
    "_"]
    return
    button "Even" [swap-even] button "Odd" [swap-odd]
    button "Debug" [print dump-face panel-rechts
    print panel-rechts/pane/1/font/color
    print panel-rechts/pane/1/color
    print panel-rechts/pane/1/style]
]

Where the first two labels change when button Odd is clicked. and 
then stay unchanged and the debug button shows the changes as expected 
(by me)

You can't simply switch the style by putting a new word in the STYLE 
facet. Each style is a prototype object with very different code 
to manage its internals. Generating a style using layout therefore 
involves getting a face from the style library, performing a set 
of operations on it for correct size and offset and run its initialization 
procedure. Only then is it inserted at the right localtion in the 
pane of the parent panel.

(But otherwise, it would be handy, if you could just do that :-))

You can study different styles using GET-STYLE.

For example:

probe get-style 'field


It's a bit misleading, though, as many styles share the same code. 
To really see how styles are built, you need to read the sourcecode 
for VID.

That is now on the wish-list!

When I name the labels lr1 thru lr8 and use the trick I found on 
www.pat665.free.fr/gtk/rebol-view.html which is w: to-word rejoin 
["lr" n] (for n is 1, 2, 3 or    8 you get the picture.) and f: get 
:w 

f/font/color: white and directly show the label: show f I can set 
them seperately. But it is a bit ugly to do it like this if I may 
say so.

Hi! Have a quick question:

Hi! Have a quick question:

i have a block of objects:
each object is constructed like...
  c: #object! [
    name: "wonderwoman"
    attribs: [
      Y1991: #object! [ a: 1 n: 2]
      Y1992: #object! [ a: 1 n: 2]
    ]
  ]

i need to sort the series based on fields of the attribs inner object
i dont want to create a new series...any ideas?

use the /compare refinement of sort (which can be a function).

>> help sort
USAGE:

    SORT series /case /skip size /compare comparator /part length /all 
    /reverse


DESCRIPTION:
     Sorts a series.
     SORT is an action value.

ARGUMENTS:
     series -- (Type: series port)

REFINEMENTS:
     /case -- Case sensitive sort.
     /skip -- Treat the series as records of fixed size.
         size -- Size of each record. (Type: integer)
     /compare -- Comparator offset, block or function.
         comparator -- (Type: integer block function)
     /part -- Sort only part of a series.
         length -- Length of series to sort. (Type: integer)
     /all -- Compare all fields
     /reverse -- Reverse sort order

hi maxim!

thanks - saw that in the docs, and also saw brett;s sort-object-series 
function on the mailing list
not quite sure how it works with an inner object though

the compare function should return true of false based on order of 
the two input arguments.

this works great for fields in a simple object series:
sort-object-series: func [
  series
  field
] [

  sort/compare series func[a b][lesser? get in a field get in b field]
]

am fumbling with the get in bit...

sf: func [a b][   a/attribs/Y1991/n > b/attribs/Y1991/n  ]

sort/compare series :sf

that was stupid of me to miss!
thanks!

no, its so simple we often think that there is more to it :-)

:)

can i introduce an additional complexity?
what if i need to sort a hash?
m: #hash! [key-a obj-a key-b obj-b]

sort/compare/skip series :sf 2
??

yep

cool! love rebol :)

but if you need to sort with sf above (which uses obj data) then 
you also need to add the index within the skip. (because the obj 
is not the first item of the fields marked with /skip

so it would be:
sort/compare/skip/index series :sf 2 2

testing it now...

doh... that's my old modified sort func...

compare is used for the index and the func... hum.

I think you get blocks of fields when you use /compare with /skip

>> blk: [1 [2  3] 0 [4 8] 5 [4 3]]
>> sort/skip blk 1
== [0 [4 8] 1 [2 3] 5 [4 3]]

sorry - that should read 
>> sort/skip blk 2

ok - am failing with the test, probably because i specified the problem 
wrongly

h: #hash! [k-a object! [
    name: "wonderwoman"
    attribs: make hash! ["1993-1994" #object! [
            rebal-year: 1993
            m: 160.018245
        ] "1992-1993" #object! [
            rebal-year: 1992
            m: 104.293
        ] "1991-1992" #object! [
            rebal-year: 1991
            m: 26.628
        ]]
...and so on...

my keys - for both the main hash and the inner hash are strings

i need to sort the hash h by the m attribute of the attribs hash
any ideas? would the same :sf work?

ok, so to get complete records, you need the /all refinement...

>> sort/skip/compare/all [1 [2  "a"] 0 [4 "z"] 5 [4 "m"]] 2 func 
[a b][a/2/2 < b/2/2 ]
== [1 [2 "a"] 5 [4 "m"] 0 [4 "z"]]

a, m, z are sorted.

yup - that works...
but would it work for the structure i posted?

yes, you just need to adapt the paths you lookup.  the sort func 
gets a pair of blocks which are the whole records, which is why I 
start with a /2 to get the second field, which is the block ... in 
your case, that would be the object

ok - thanks maxim
trrying it now

any luck with the new release of mod-web-api?

...and the json data structure?

the mod has been so heavily modified, its almost a complete rewrite. 
 its also heavily embeded within our production environement (libs 
and stuff) so that making it a stand-alone mod again will take some 
time... some time which currently, I don't have.  though note that 
we didin't actually add json support but greatly increased the flexibility 
of the i/o format conversion.

sounds great...since i'm a noob, not sure i can help, but will gladly 
pitch in

we neededed to support, xml rest, SOAP and direct get/post interface 
to the same functions, and that is now working via a configuration, 
which allows you to tweak how the url is read and switch interfaces 
on the fly.

I also added path support for the mod so that you can use the same 
domain for web and api services.

wow - cool!

any chance i can get to play with the code?
