Using 'merge on a  GIF image crashed view.. also the beta's crash..is 
this known ?

How does one shut down all the events initiated by do-events ( wait 
[] ) ?

halt ;?

yeah ... not really.

I'm getting a 100% cpu when I do a wait inside a uniserve protocol... 
so I want to kill all the waits so I can restart the whole process 
after a period.

one way is to break wait is to throw an error, as long as it is not 
catched in between. 

another to use wait with timeout, and "poll" a variable every second 
or so.

hmm, that would fail with nested waits..

'halt may be an option, because you can put code in system/options/prompt, 
and if the console want to draw the next ">>", it restarts the main-loop 
:) but do not know how stable that is.

but do you really need the wait? or could you give the thing you 
wait for a fresh /awake, and return?

seems to be working without breaking the wait .. no longer a busy 
wait.  Odd.

Oh, well, can't complain... :)

what's the facet now for a password field ?  Not value, and not text 
...

/data

thanks...

how do I display a GIF image with a transparent background. The GIF 
image is White and Blue and the background of the image is BLACK. 
I want to make the BLACK part transparent to its background face 
it is floating on. (The image is dragged and dropped). Is this possible 
??

I think im using the wrong GIF format tool..

Ha ..pffff its was PAINT from windows who did it wrong..sorry folks..

You can make any color of an image tranparent with the KEY effect 
keyword.

view layout [space 0 backdrop help.gif image logo.gif effect [key 
254.254.254] image logo.gif effect [key 2.2.2]]

Yes it worked fine.. the problem was the paint program that confused 
me ;-)

Thanks anyway

How do I ctach in which 'face I am when using 'Detect for events?

I have currently this ->

and want to detect per face.. Do i need to Name the face perhpas?

view layout [
	origin 0x0
	space 0x0
	size 400x400
	at 0x0 box 300x300 aqua 
	at 200x100 box 200x300 linen
	at 0x100 box "In the middle" 400x200 khaki feel [
	        detect: func [face event] [
            		if event/type = 'move [	
				popup/text: event/offset - 0x100 
				popup/offset: event/offset + 10x0
				show popup
			]
		return none			
		]

 ] font [ size: 72 ] effect reduce [ 'merge 'colorize 128.64.128 ] 
 	

	popup: box 50x15 font [color: white size: 10 shadow: none ] 

  effect reduce [ 'merge 'colorize 128.64.255 'draw [ pen 0.128.0 box 
  0x0 49x14 ]]
]

Or do i need to create an event per face ? actualy i want to Roam 
over the main face an select the face i am moving over ta that time...uable 
to comply  currently ;-)

OLDES !!! Thanks for your "Bezier Demo!!!" I was seeking for that 
;-)

Does the Bezier demo answer to your question above ?

Using insert-event-func is probably the way to go. event/face should 
have what you want. (if you don't already have an answer)

With insert-event-funcs, face and event/face are the window face 
where the event happens. You have to search yourself what is the 
face under the cursor. Very boring OMO.

I thought the face param was the main face and event face was the 
face getting the actual event, in the case of 'move, etc.

face is always screen-face and face/event is the window.

Oldes: is "Bezier Demo " an public script?

If have a problem with Caching in rebol..seems everytime i need to 
restart view/console to make sure the PICTURE is reloaded to the 
currect on... im using 'IMAGE %file.png to load it... and a recycle 
does not fix the problem

image caches files somewhere.

load-image/clear should help

yes its 'image indeed.. a simple load works.. though load-image also 
has this problem... Ill try your hint!

layout [image with [?? multi]]

You can see under "file:", that LOAD-IMAGE is used. Check the source 
for load-image and the second item (a block) is where the images 
are actually cached.

( see [help load-image]. load-image keeps a cache. load-image/clear 
clears that cache. ah, there is load-image/update too for refresh.)

For every View Question there is an Answer ;-) Thanks...

You're right Dide, I had to look, then realized I used system/view/focal-face 
to get it where I needed it in one app.

If I have a layout is it possible to just add stuff on-the-fly if 
certain conditions are met? Like this:
	layout [
		...
		if my-var > 5 [name: button red return]
		...
	]

Of course it's possible to build the layout block up front using 
normal Rebol code but IMO being able to do it inline makes a lot 
of sense.

I felt this need a few times too. But what syntax is desired ?

layout [

 do [if my-var > 5 [layin [name: button red return]]]  ; something 
 like this ?
]

Woudl be OK. It should be acceptable in that it's easy to remember 
and doesn't interrupt the programming flow.

Anybody of some generic form validation scripts/hints.  I like how 
.Net allows you to validate a group of radio buttons with one command 
rather than having to code a check for each radio button in the group.

interesting idea. I usually use

 compose[ .. (either my-var > 5 [[name: button red return]][()]) ..]
but its a lot of brackets

When I selectively compose in several times like Volker's code above, 
I make a small helper function called FLAG-VAL, to do the same job 
as the EITHER.
