button_a: btn "hello" with [data: dat]

so button_a/data will be for the post build access

ok...
Got it...Thanks

I'm building a panel dynamicaly and need to assign data to the face 
as its being built. 
I was not sure of the format: of the with refinement.

back to choose function...
can't get the styl attribute to work. 

If I want my choose menu to be a certain width what syntax do I use?

choose/offset/styl ["One" "Two" "Three"] func [face] [print sec] 
'offset' size = 200] ????

view layout [choice 200x20 "one" "two" "three" [probe face/data]] 
;??

sorry oldes...

Not vid's Choice button style but the choose function from which 
its derived.

(The CHOOSE function uses the CHOICE style, yes.)

view window: layout [
	style choice choice 200x50
	size 300x200 button "choose" [
		choose/window/offset/style ["one" "two"] func [face value][
			probe face/text
		] 
		window 
		(face/size * 0x1 + win-offset? face)
		window/styles/choice
	]
]

soany of you have ideas for the new nale of view ?

nale = name

new name for vid3.4...

no new name has been decided yet

the first name was GIDI ....

Anton,
That works great..Thanks again.

I was looking for syntax where you describe the layout in hte function 
but I guess that's not how its done. 

Funny how I only saw one example of using choice as a drop down menu 
system. It works perfect for what I need witout hte any bloat. (unless 
you need sub-menus this is fine.

You can even leave out hte window refinement and the menu will drop 
outside the main window. Perfect for when you have a need for a menu 
at the bottom of a window.

and in that case, you would use SCREEN-OFFSET? instead of WIN-OFFSET? 
to help calculate the offset of the popup window.

But note, currently in linux, on KDE at least, the popup window has 
a title bar and borders... A limitation of rebol at the moment.

screen-offset? 
I actually figured that one out myself...for once.
how about OSX? Does it display properly?

Does ToSystemTray work on a  Linux box?

Doesn't look like rebview supports any trays on linux

I've revised (and am still working on) my arrow360 style:

load-thru/update http://anton.wildit.net.au/rebol/gui/arrow360.r

do-thru/update http://anton.wildit.net.au/rebol/gui/demo-arrow360.r

And here's why I wanted it - I wanted to explore the abilities of 
TEXT facet rendering, changing parameters in FONT and PARA objects.

do-thru http://anton.wildit.net.au/rebol/doc/text-facet-rendering.r

(still in development, but you can click and drag the pair-edit fields 
to see the arrows appear.)

neat. I'm looking at it through a 256 color remote desktop. Is there 
supposed to be a darker box around the arrow? Maybe it's just an 
artifact of my remote desktop.

Your text-facet-rendering.r gives an error back about 'push has no 
value.

darker box:  Yes. I'm making the face visible to help develop the 
face/offset and size calculations, and also to help demonstrate how 
the arrow360 is implemented.

Henrik, try this to update some dependencies of text-facet-rendering.r 
(1-level deep only), then try it again.

site: http://anton.wildit.net.au/rebol/

foreach [file words] select load-thru site/doc/text-facet-rendering.r 
[include][
	print file load-thru/update (do file)
]

Anton, that's a great style.

Thanks, Brock. I agree ! :-) It's very useful right now, though to 
make it perfect I need to do the vector calculations using decimal! 
instead of pair! to avoid visible loss of precision (when using not-too-extreme 
parameters).

Graham, forgive me if I am wrong but I recall you made a simple draw 
program with annotations and undo feature.  Did you ever publish 
it?

I see Paint.r in the Demo folder from the Rebol Desktop, had you 
done more work than that?  I'm also considering trying something 
with the vector graphics to allow for drawing of arcs etc.

Henrik, I can't figure out the reason for the "'push has no value" 
error you got above. I had an issue with 'push in some other code 
of mine (dir-utils.r, I think), but there's apparently no push in 
any of the dependencies of text-facet-rendering.r.  The only thing 
I can think of is that some files are out-of-date, or perhaps you 
didn't start with a fresh rebol ? What version did you try running 
? I've tested on View 2.7.6.4.2 and 2.7.6.3.1 on linux.

I think I got it... hang on..

My .... memory is getting worse. This was a dependency bug I caught 
and fixed just 7 days ago. :)
Please try:

Is there a way to append an image object (a box for example) to a 
face that has already been displayed. I'm looking to get  simple 
highlight functionality in an app in which a string is scanned for 
in a series of text faces. 


I've been  able to highlight the search word in each face but if 
I click in any of the text faces the face looses the highlight effect 
sort of like loosing focus on normal highlighting. 
I would like the highlight to remain until no longer needed.

you could have the boxes there already and just hide them until you 
need them.

The string is meant to be a search keyword which can change. No predicting 
what one might seach for...

What I got working:

rebol []
pad: 20x30

	bx: box red 0x0
	panel: panel [

The first button hilights a string.
The second button "paint" the string in red.

The last painted string in hte last face remains when  clicked in 
the face but the others disappear when clicked. How can I prevent 
that from happening?

Ignore the commented out lines...

if possible, you should append faces in a pane that belongs to the 
text face. you can do that as you want. it's only a matter of regular 
block manipulation and then SHOWing the text face again.
