OK, submitted this bug and fix to RAMBO.

Thanks! :-)

I have a problem with the arrow style. It's default pointing up, 
but should be able to be rotated (according to the old REBOL/View 
Developer's Guide) like:

view layout [arrow effect [rotate 90]]


I can't get it to work in View 1.3 or View 1.2 for that matter. Is 
it a real old not found bug, or am I doing something wrong?

Oh, this works:

view layout [arrow right]

so maybe the rotation is not needed.

Do this and you will see why your first test didn't work:

layout [arrow with [?? init]]

So to use effect with arrow, you have to do something like this:

view layout [arrow effect [fit arrow black 0.7 rotate 90]]
same as:
view layout [arrow right]

Geomol, what were you doing when you discovered the slider bug, above 
? I would like to know the reason why you needed that functionality. 
It might be good in the bug report.

Anton, I was producing the quick list of VID-styles found on my homepage 
and needed some images to go with it. I saw the bug, when I was making 
the image to show slider functionality.

Great, thanks. That's the same reason (documentation) I stumbled 
on this long ago. Now it's in rambo it can't escape.

work in progress:  do http://krutek.info/rebol/styles/demo.r

there is a bug somewhere ...

knob.r or tachometer.r - run clean View session ....

ah, now it works, strange ...

yes there was a bug

it's fixed now

Visually it is really nice, but it is nearly impossible to move the 
knob. When I drag it around, it does not follow the mouse ...

that's because you must drag mouse up/down and not in circle

I am not sure it should work by dragging the mouse up and down ... 
you should be able to hold the knob and do circular movement imo 
...

I'll probably add circular movement too - but IMO mouse really not 
suitable for circular movements (try to paint a circle with mouse...)

in Cubase there's option for up/down or circular movement for knobs, 
I'll add it later (it's just work in progress)

Pekr, there's a reason why up/down is the preferred way. It's weird 
to start with but it's better control in the long run. The hand is 
more precise in just one direction of mouse movement than two (or 
more, as you might like to see it).

Kru, nice demo ! :) Incidentally, this is just what I have been working 
hard on the last couple of days. Now I must post a demo :)

do http://www.lexicon.net/antonr/rebol/gui/demo-rotate-knob.r

In Reason and FruityLoops (audio sequencing software), up/down is 
the default behaviour.

Anton I'm working on a french rebol software witch names is FaireBo 
it's a weather dashboard  based on METAR/TAF information so I need 
a kind of widget like  the ones you give in your demo to symbolise 
the wind direction  ;)

METAR/ TAF information are comming from airports weather system and 
are usefull in aeronautic

I don't understand why the big view is so aliased

Is it really close to what you need ? If you can show me a picture 
of how the widget should look, I can see if rotate-knob can do it.

The big view is for looking at the pixels. It needs to be non-antialiased.

You can scale each widget by dragging on it then dragging on the 
pair-edit.

what I would like is a cardinal roze of the wind with a dynamical 
arrow that symbolise the wind direction according to the data comming 
from the weather station in the airports

I need to symbolise 8 directions N, NE , E, SE, S, SO, O, NO,

so up, up-right, right, down-right,  down, down-left, left, left-up

this are the direction where the dynamic arrow can be displayed

So, every 45 degres ?

My point is O I make 8 images and show the  right one according to 
the datas

yes ,)

What if there is no wind ?

or I make one image and I make a dynamic arrow using draw effects

Il ne souffle.

there is always wind  ;)

Every 45 degrees can be programmed by setting  rotate-knob-face/divisions: 
45

even if the wind speed is not enought significant

:)

for example today  on paris we have wind from north  N (360) speed 
12 KT.

OK, wind speed is shown by another widget.

in all cases your code is a good example  and a usefull working pass 
for me

Umm, I would need to add the ability to place multiple texts (N, 
NE, E ...) at any position in the face (I will use draw dialect).

Actually in the fairebo's dashboard  I only symbolise weather and 
temperature and for complete weather description we have to report 
to the text report (witch translate the METAR/TAF informations)
