aha, I see. Thanks Anton
It looks OK, but actually, it's not working.
>> layout [panel with [b: none][face/b: button]]
Misplaced item: face/b:
Anton you're right with 'face in action block, but what I want is 
to have local words not in action but in panel definition block.

oops I see.
That's what happens when I don't test first.

So you might rename CTX to VARS to give it a meaningful name.
The above approach (storing the words in a context) makes it safe 
to add variables of any name (without having to check if it would 
override a some facet of the panel style).

Yes, that works. Great, Anton!

anton:  WRT license,  (I had found that one  ;-) this only tells 
you that a pro license is installed... not the components which it 
enables...
since components of the pro package have changed from one version 
to another... its getting a bit tedious to hope everything is properly 
mapped...
and we aren't talking of other obscure packages like dll, link, sdk... 
for which I have no clue what is enabled.

I tried to create with the following code a circle with a transparent 
background and save it. I tried some different versions, but currently 
I have no glue how to achieve this. The point is I need a file with 
a circle and a transparent background :-) and I thought I quickly 
do this with Rebol instead of using a paintprogram. So am I doing 
something wrong ? It's saving the background from the window and 
if that is set to 'none then it's black ?

view layout [
    b: box 22x22 effect [
        draw [pen red line-width 2 circle 11x11 10]
    ]
    across 
    f: field 200 button "Save" [
        file-name: to-file f/text

        unless find/last file-name ".png" [append file-name ".png"]
        save/png file-name to-image b
    ]
]

Found these words:
   rebol-command?  logic!    false
   rebol-encap?    logic!    false
   rebol-link?     logic!    false
   rebol-pro?      logic!    false

repeat n length? i [t: i/:n t/4: 255 - t/1 poke i n t]

Thanks Gabriele, didn't even know that draw is a function which can 
be used stand-alone. (thanks to Geomol of course as well :-)

Im getting all the time the same errors from /view 1.3.2.3.1 anyone 
kows if thats a known problem?
** Script Error: Invalid path value: dirty?
** Where: evt-func
** Near: if all [
    system/view/focal-face
    event/type = 'down
    not within? event/offset win-offset? system/view/focal-...
>>
>> unview
>> system/version
== 1.3.2.3.1
It always happens during events with the mouse.. like drag and drop 
up/down while dragging out of the window etc..

Maybe you use custom faces not based on 'VID-face but on 'face object, 
so there is some "properties" missing in your faces.


This code is from the global event handler and handle field/area 
loose of focus :

	 probe system/view/screen-face/feel/event-funcs
View set system/view/focal-face to editable face only (field, area).

So if you use it for other type of face that did not have 'dirty? 
property ==> Error!

Seems to work OK here.

Are you sure you don't have any special things in your %user.r file?
It's usually a things to check.

Well now you mentioned it.. I had a look and its stuffed with 'Steel 
configurations.. Let me remove those ;-)
Who created the Images in the document http://www.rebol.com/docs/view-system.html
 ??? I mean the Data-flow images...can the person in question please 
contact me ;-)
Because I wonder if they where made with the draw dialect? If so 
then i would like to know how.. Im unable to immitate that effect...

I think they were from Carl or his son. Just a guess. Non-rebol.

When does this happen -->
** Script Error: Not enough memory

** Near: show main

?
Im using Layout where im appending panes into layouts.. But i dont 
think thats the problem... The problem is resizing an 'effect to 
negative numbers... like a box from 0x0 500x500 to ->  -50x0 -100x100 
...and only using it in the Engage event... Odd?? anyone an explanation 
perhaps ? This is Linux /rebview from SDk262

Sounds like a bug. What is the effect block which shows the error 
?

By the way... Is there any news on the Right Text Formatting inside 
Rebol? Will it be in? or is there a special project for RTF ?

AFAIK RTF is ready, but I'm afraid we have to wait for R3 :/
