barebones of a button, one with behavior and simple look (two colors), 
another shows smart vid-arguments (all this "if color if effect" 
etc).

OK, then it really is question of documentation mainly, but still 
- if we can find good ways to make things more consistent, we should 
not hesitate to discuss them ...

Right. And it helps. If you say "i like the pure OO way because of 
..", i start saying "Noo, our way is better because of - because 
of - " and then i have to dig out something. Only that i always forget 
to make notes..

This is OK?

>> 334x252 > 300x300
** Script Error: Expected one of: pair! - not: pair!
** Near: 334x252 > 300x300

Such a comparision doesn't make sense. So > shouldn't work for pair! 
(more specific for two pair!)

So, the error message is a bit confusing.

Is there a way to hide the mouse pointer in view  when its over a 
face ?

No one except playing with Win32 API (good luck)

Maybe a good enhancement request.

mouse pointer handler was previously announced http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-thread.r?m=rmlZNLK

Shouldn't changing FONT/OFFSET have an effect? I must be doing something 
seriously wrong, here ...

I don't think font/offset does anything since I can remember.

Hello y'all. Does anyone know how to correct the following? I have 
a "list" of toggle buttons in four columns. When I select one of 
them, any time I move my mouse, it will continue to select any button 
in the same column that the mouse pointer passes over. The same thing 
happens with text buttons.

show the code

my-list: list 247x300 [
        across space 1x0 origin 0x0
        style cell toggle 60x20 blue mint + 25 center middle [
       
       
        	either found? find selectedtimes face/text [

          remove at selectedtimes index? find selectedtimes face/text head 
          selectedtimes 
        	]
        	[append selectedtimes copy face/text ]
	
        ]
        
        
        c-1: cell cell cell cell
           ] supply [
	        count: count + ml-cnt
	        item: pick data count
	        face/text: either item [pick item index][none]
    	]
    	sld: scroller 16x300 [ 

        if ml-cnt <> (val: to-integer value * subtract length? data visible-rows) 
        [
            ml-cnt: val
            show my-list
        	]
        ]

hmm... now I'm learning again... what does 'supply do? :-)

It's supposed to fill in the face text data as View generates the 
buttons.

faces with state do not work with list. because all the displayed 
faces are the same face internally, and share that state. if you 
change state of one, say toggling, all toggles have that state.

Remember they are all one face, a face which is changing its position 
rapidly.
Now look at the cell face's feel:
	layout [toggle with [?? feel]]

In this code, if you see facets which are modified then those need 
to be stored and restored by the SUPPLY code. (ie. just like the 
list data goes to face/text.)
But wait, let me look for an iterated checkbox example.

if you need such toggles, its easier to make a big layout with a 
real face for each row.

Is there a way to generate buttons on the fly? I've often wondered 
about that.

But thank you all, your explanations make sense.

do http://www.lexicon.net/antonr/rebol/gui/iterated/list-of-checks.r

Yes there is. After all vid-styles are faces, and can be used at 
that level, means put in a face/pane.

Didier's delete-email.r has a text list that seems to work. I'll 
have to check to see what he is doing differently.

the easiest way imho is to make the button in a layout and throw 
the layout away.
  layout/tight[my-button: button "test" [..]]

and now you have a button in 'my-button, which you can use in another 
face/pane

Thanks all.

Hmm, Antons way works too. He has all face-states extra in a block. 
In supply he puts it in the face, and in action-block, when it is 
changed, he puts that value back in the block. That could be used 
now with set-face/get-face with some styles.

I'll check that out.

do http://www.lexicon.net/antonr/rebol/gui/iterated/list-of-toggles.r

Thanks Anton!

Cyphre, my compliments on the nice demos on your site... I like SWIS 
and the vconsole rocks :)

James, cool. Hope it helped. Just uploaded improved version in which 
the list is more self-contained (not so many external variables lying 
around).

(essentially the same.) More fiddling involved with a list of buttons, 
though. The button style feel must be modified to save the state 
when it changes in engage, such as when the mouse drags off the button 
(and then perhaps back on again.)...

Thanks. I'll take a look at it. Man, how do you know this stuff?

Anton, I thought your example was superb. I started to adapt it to 
my "grid" of toggles but as usual I'm not thoroughly understanding 
what's going on and I can't make my 4 x 48 grid without the rows 
being the same toggle.

Is it or isnt it...the mouse-wheel in rebol..? looks not...

it is ...

http://www.rebol.com/docs/view-system.html#section-5.10- look at 
scroll-line and scroll-page events ...

Some week or two ago someone posted kind of visual app to see even-flow 
... maybe link could be reposted here, but dunno if it featured mouse 
wheel events ....

Thanks... !

You can process mouse wheel events in view .... AltMe does it for 
example .... I believe that the event type is  .... event/type = 
'scroll-line

Does anyone have a good performance with Rebol/view and i.e. Hummingbird 
Remote Desktop?  Seems Rebol is quiet slow here where GTK GUI is 
flashing over my screen my Rebol gui's do need far more time..
Any hint of tip is welcome..

I previously used this for buttons with images :


view layout [ button "Reply" 60 font [align: 'right] myimage effect
[] ]

but this doesn't work for btn

view layout [ btn "Reply" 60 font [align: 'right] myimage effect
[] ]

myimage: load 64#{

view layout [btn "Reply" 60 effect [extend draw [image 5x5 myimage]] 
para [origin: 20x2]]

Kewl .. thanks.

James, what do you want to do with your grid of toggles ? (sounds 
like could be used for an audio application, like drum patterns). 
Do you want them to have different texts and colors as well, etc. 
?
