New error for me ..


An error has occurred.  If this occurred with an upgrade, please 
revert to the older version for the meantime, and report the error 
message as documented below.

Well, that looks like the face-iterator logic (used by table and 
text-list) ... any idea what was being done at the time (i.e. table 
just about to be displayed, row double-clicked on, etc)?

None of those as I recall.

Build#95 uploaded to SVN. Contains new 'on keyword and request-char 
function. 'on is used to specify multiple action handlers at once, 
as in:

	display "" [
		field
		field on [
			scroll [print scroll/y]
			focus [print "Got here!"]
		]
	]

%tour.r updated to demonstrate new request-char function.

Ashley;  How hard would it be to allow set-path! for widget variables? 
 Or am I missing

something that would allow widget variables to be held in an object!? 
 I'm fairly prone
to missing things  :)

You mean something like:

	b: "Bob"
	display "" [a: field b]

which is already supported, or something else?

No I mean something like

fields: make object! [
   a: b: c: none
]

display "Test" [fields/a: field  fields/b: field  fields/c: field]

No [to supporting that]. The preferred approach would be:

	obj: make object! [
		a: "Bob"
		f: does [display "" [field b]]
	]
	obj/f

typo "field b" -> "field a"

Thanks Ashley.

Would pathes help? I think the change to support that could be small.

I was looking at (and don't grasp all the implications of) the parsing 
 set-word!  occurances and how a set-path! may be inserted.  But...it 
looked too simple, so it had to be wrong.  :)  And again, I don't 
get all the implications, so I'm completely accepting of Ashley's 
nice short no.

face-iterator init func as it tries to create a table ... now that 
one should be reproducable?

I'm just logging errors here as they occur!

so I can add traps around them and then log them to the rebgui.log

Are these errors you're generating or your users are generating? 
I've got a dozen or so users who've been pounding away at a large 
RebGUI app for almost 2 years now, and the rebgui.log files on their 
PC's are pretty much empty. Might just be a case of YMMV ;)

these are ones I am generating :(

btiffin, maybe this works:
fields: context [a: b: c: none]

display "test" compose [(to-set-word in fields 'a) field (to-set-word 
in fields 'b) field]

Hey...that should get rid of a few more globals, cool.  Thanks Ashley. 
 First tests worked great. :)

Anton, very cool. I'll think I'll add that trick to the [RebGUI] 
cookbook.

Anton;  Yep, thanks.  This has opened up all kinds of RebGUI goodness.

well, but will it bind those variables to those one in 'fields object?

Ah it works, good :) I couldn't remember if the binding was kept 
or not.

Pekr, do you know what   in fields 'a   means ?

yes, from the help ....

I am just not sure, if the 'a in the 'display is the same as in the 
'fields ....

Check this out:
>> o1: context [a: 1]
>> o2: context [a: 200]
>> print probe compose [(in o1 'a) (in o2 'a)]
[a a]
1 200

I mean - does it create global 'a, referencing fields/a?

The only concern for me was if to-set-word kept the binding. (I guess, 
possibly, long ago it did not.)

yes, but you are creating global var anyway, no? via the set-word?

sorry ... not good at those topics :-)

No,   in object 'word   actually refers to the word that is in that 
object. :)

Try the above example, then see if 'a has a value globally.

eh .... can't believe it :-) it should translate into: display "text" 
[a: field b: field]

your above example does not use setword

No, to-set-word keeps the binding of the word (thankfully).

shit, it works :-)

o: context [a: 1]
print o/a
reduce compose [(to-set-word in o 'a) 5]    
print o/a
value? 'a

results:
1
5
false

it is just not clear, how to-set-word could bind it to o's 'a

>> blk: compose [(to-set-word in o1 'a) (to-set-word in o2 'a)]
== [a: a:]
>> get blk/1
== 1
>> get blk/2
== 200

to-set-word is not doing any binding. The word retains its binding. 
Each word knows to which context it is bound.

So, as the word travels around the place, it knows in which object 
its associated value can be found.

ah, that is like sucking 'a from object to upper context, while 'a 
still remembers, where it belongs ;-)

We should move to Core group.

Just ran RebGUI from the Desktop Demos folder:

** Script Error: yello has no value
** Where: append-message
** Near: get msg-color

yello is a new colour since....

since View1.3.2

I'm post-1.3.2, but clearly a little behind...

system/version?
