set-face does not allow [a: ...] while it should. I have a fix for 
it if you are interested.

ok, I have to read up on 'panel first :-)

if it's documented...

you could set the window accessor object to the default panel accessor 
objects, so that you can do the above with the window directly too.

using panel is useful if you have more than one panel in the window.

hmm... it actually does exactly what I need

basically I'm interested in taking the contents of an object and 
put it in various faces in a layout in one go

what i do exactly.

my-access: make ctx-access/panel [
    set-face*: func [face value /local val][
        if all [block? face/pane block? value][
            either set-word? value/1 [
                foreach [word val] value [
                    set-find-var face/pane to word! word val
                ]
            ] [
                foreach f face/pane [

                    if any [find f/flags 'input find f/flags 'panel] [
                        if not empty? value [
                            set-face f value/1
                            value: next value
                        ]
                    ]
                ]
            ]
        ]
    ]
]

Gabriele should your fix make it to the default distribution ?

then use Panel with [access: my-access]

Jaime: it should. as soon as I get the chance to work on mezz code 
again.

with that you can do:   set-face panel third object

context get-face panel    gives you back the  object.

(or better make template-obj get-face panel)

; Here's a quickie:
ctx-busy: context load http://www.ross-gill.com/r/busy-style.r

view center-face layout [backcolor snow origin 200x150 busy true 
coal]

Hey that came form OSX! Nice.

nice :-)

Why not use the firefox busy style ... open source.

That's really cute, Chris! :-)

hrm. Having issues getting "show" to work right for me. Time to dig 
a little and see what I can find out...

Ok, I've tried... I have a list of toggles with a scroller attached. 
For the life of me I can't get the "dragger" to size properly. The 
slider button is not proportional to the what is being shown in the 
list. In my case, I'm seeing about 20 of the 24 rows so the dragger 
should be about 80% the size of the panel, no? Thanks in advance 
to anyone who knows.

James,  The code?

Rebol Lesson #3:  "An object can contain variables that refer to 
functions that are defined within the context of the object." Therefore, 
don't assume an object's path leads one to having a value '"shoved 
into" it replacing the current value. In other words, sometimes all 
it takes is noticing that there isn't a ":" (colon) following the 
path. In Judeo-Christian lingo: "Thou shall not murder a function 
held in an object."  Man, I didn't notice that scroller_object/redrag 
holds a function and just requires a value to be passed to it!  When 
will I ever learn? Thanks MikeL. The phrase, "The code?" caused me 
to notice that.

Almost there. What controls the amount of scroll when the user drags 
the bar up or down. I want my bar to move in increments of one row 
at a time but it seems like I have way too fine of a value in there 
to the point where the program has to catch up to the user's movements 
after a while. I would think it would be obj/step.

The code ? :)

I'm expecting you're doing a show every time there is a scroller 
movement. What you want to do is check if the current row (ie. the 
one at the top of your list) has changed If so, show the list. If 
not, ignore. Not all the shows are necessary.

James, this example might help:

do http://www.lexicon.net/antonr/rebol/gui/iterated/demo-vid-list-scroller.r

The STEP facet is what you want to set. This snippet from the above 
script does the work:

	; arrow buttons cause the slider to move by the value of step

 scroll/step: either zero? non-visible-part [0][1 / non-visible-part]

Since customizing buttons comes sometimes up, i just found this link: 
http://www.rebol.com/how-to/btns-cust.html. Did not know that image 
can do that :)

Oh Anton-san, you very wise. The step was set correctly but it was 
indeed the # of "shows" that were being performed. I just check the 
before and after offset and do the show if necessary. Thanks.

Is there a way to draw a dot with the draw dialect? I'm looking for 
a way to do it with the draw dialect, and not just a poke in the 
image, so e.g. line-width will take effect. A line, where start- 
and end-point is the same, is not shown. A circle with radius 1 is 
not a dot, but slightly larger. Any ideas?

does a circle with radius 0.5 work for you?

No, and even smaller does not work either:

view layout [i: image black effect [draw [anti-alias off  circle 
10x10 0.0001]] image (i/size * 5) (to-image i)]

This might be a way:

view layout [i: image black effect [draw [anti-alias off scale 0.1 
1 line 100x10 101x10 scale 1 1]] image (i/size * 5) (to-image i)]

Seems crazy that you can't just draw a dot, doesn't it ?

Here is another way:

view layout [i: image black effect [draw [anti-alias off shape [move 
10x10 hline 10.1]]] image (i/size * 5) (to-image i)]

Really need a SET-PIXEL or DOT command just for drawing single pixels. 
These other ways are a bit unwieldy.

I am sure Cyphre has this on his to do list already.

Is there any documentation on how the windowsXP-like buttons in View1.3 
are made? They are bitmapped, right? I remember the community help 
that Carl had for making this over a year ago for the first betas. 
I will need this for some custom buttons for a project that I'm going 
to do; converting a fully graphical HTML GUI to VID while it keeps 
the same look.

Yes, they use an image and the EXTEND effect, indeed:
	print mold svv/vid-styles/btn/init
	? .png
	layout [b: btn "hello"]  b/effect

thanks

As to making the images, Chris is into this stuff.

Here's an old script of mine you might find useful:
