; Yep, 'merge instructs the effects engine to compose effects using 
underlying faces:

view center-face layout [
    backtile dots
    image img
    image img effect [blur blur blur]
    image img effect [merge blur blur blur]
]

'merge was added in 1.2.8 or 1.2.10. It was by default in 1.2.1 AFAIK

'fill : to fill a form

view layout [box 100x100 effect [draw [pen 255.0.0 fill-pen 0.0.255 
polygon 0x0 0x90 90x90 fill 50x50]]]

'activate-on-show : like the name said.

There is different behaviour with it. I notice that on Win2k, the 
window come to front but don't take the window focus. sometimes, 
the window stay behind and just the task button blink (the current 
active window remain active).

But on WinXP, the window become active and take the window focus. 
Very annoying when you are typing something.

I use it to bring a window to top when there is something new (lecture-forum 
script).
I don't w=know how it works on Linux.

merge (with Chris's example) behaves differently under 1.2.10 and 
1.2.48 (later is correct)

fill (DideC's example) dosen't seem to do anything (same result by 
removing the "fill 50x50" bit)

I know that fill is not working on AGG alpha version (problem due 
to antialias).
On what version did you found 'fill not working ?

what=witch

My example give different results :

on 1.2.1, 1.2.8 and 1.2.10, fill is OK, but there is not the red 
line.
on 1.2.48, it's ok

'min-size : I missed that. Nice thnigs to know :-)

Tried on both 1.2.10 and 1.2.48. Note that the lack of a red line 
on 1.2.10 is due to a known bug with polygon (fixed in 1.2.48).

On 1.2.48 I can't see a difference between:


a) view layout [box 100x100 effect [draw [pen 255.0.0 fill-pen 0.0.255 
polygon 0x0 0x90 90x90 fill 50x50]]]

b) view layout [box 100x100 effect [draw [pen 255.0.0 fill-pen 0.0.255 
polygon 0x0 0x90 90x90]]]

So I'm still not sure what 'fill is supposed to do. ;)

same on 1.2.1 - DideC, are you sure it's not 'flood? in your example, 
it's specifing the fill-pen who fills the 'polygon (by default, fill-pen: 
none)

Yes, I'm wrong. 'fill is ignored on 1.2.8 and 1.2.48 :

view layout [box 100x100 effect [draw [pen 255.0.0 fill-pen 0.0.255 
polygon 0x0 0x90 90x90 fill 90x0]]]

 view layout [box 100x100 effect [draw [pen 255.0.0 fill-pen 0.0.255 
 fill 0x0 0x90 90x90 90x0]]]

Not meaning to be a pest ;) , but I could really use some help with 
the problem I posted above (my latest posts).  It's a problem with 
button text disappearing when using a rebol function.

You're correct -- it is 'clear-fields.  When you set the text value 
for the 'application field, it comes directly from the face/text 
of the last clicked toggle button, ie. it is the same value.  When 
you 'clear-fields the application field, it does 'clear on that value 
clearing the field and the last clicked toggle.  A quick fix would 
be:
    if last-sgrp <> "" [application/text: copy last-sgrp]
or
    if last-sgrp <> "" [change clear application/text last-sgrp]

; the latter retains the same string value for the application field...

(I make that line 49...)

; A bonus tip -- each of the tog actions in dex-pane2 are essentially 
the same.  You could clean up as follows:
tog-action: [
    write clipboard:// join "se sa**/" [
        last-sgrp: face/text "ca datp/" get-report-date/delim
    ]
]

dex-pane2: layout [
    across
    label "Search Criteria:"
    t1: tog "o79" tog-action
    t2: tog "p23" tog-action
    t3: tog "o88" tog-action
    t4: tog "p11" tog-action
]

Brock, check out the source of CLEAR-FACE, and you will see that 
it tries to do  
	face/access/clear-face*

, therefore you should look at the access object to see what it really 
does:
	layout [text with [?? access]]

There, you will also see RESET-FACE, which would have also solved 
your problem

because it does a COPY as well. I think COPYing to start with as 
Chris showed is a safer way, though.

Chris and Anton, thanks for taking a look and making the above suggestions. 
 It looks like there is a simple solution mentioned by Chris and 
I will study the additional suggestions from Anton.  Thanks again.

I didn't get to code cleanup you suggested, but it was on my mind, 
I didn't want to post it that way - you caught me  ;)

Chris, looking at your [change clear application/text last-sgrp] 
suggestion.  I don't see any obvious reason I would want to use this 
method other than it being more REBOLish, and/or avoids falling into 
the trap of missing the 'copy statement.  Can you please suggest 
why?

When you press a tog, this happens:
	last-sgrp: t1/text
Now  t1/text  and  last-sgrp  are pointing to the same string.
When new-ticket is done, this happens:
	application/text: last-sgrp

Now  t1/text, last-sgrp and application/text are all pointing to 
the same string.

These two examples show the difference more clearly:

view window: layout [
	f: field
	b: button "clone me" [f/text: b/text show window]
	button "clear-fields" [clear-fields window show window]
]

view window: layout [
	f: field
	b: button "copy me" [f/text: copy b/text show window]
	button "clear-fields" [clear-fields window show window]
]

AntonThanks for providing further info on the use of 'copy in this 
situation.

No worries. Usually these problems are result of a missing COPY. 
The rule is; whenever you set a string, think if it could be modified 
by anything.

(not just strings - all series! types actually)

Here is another small optimization:
s: join rsd/year either delim [
	["/" two-digits rsd/month "/" two-digits rsd/day]
][
	[two-digits rsd/month two-digits rsd/day]
]

http://www.opentv.com/onair/shopping/- kind of apps which View could 
excell at. Do you remember Gateway catalog demo?

Brock: where I am tempted to use 'copy, I'm often try and think of 
any potential benefits of using series modifiers instead.  Depends 
on the situation I suppose...

howto: append a block to list (view) during runtime from a function. 
how can I address the data from the listobject ?

Is there a way to constrain the size of a Draw text object?  eg. 
[pen black text 10x10 200x200 "My Text Here"]

Guest: that depends on how you are using the List style as it is 
fairly open-ended.

list or text-list? with list you keep your own data. with text-list 
 append tl/data [lines]  show tl/update
IIRC

size of draw-text: you want wrapping? afaik not. there is a complicated 
handmade way, you make a face of that size with 'wrap and use that 
to calculate the lines.

Max has a function to calculate the wrapping: http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-message.r?m=rmlMYRC

I have a text-list in a layout and I have a simple log-function:
log: func [message [string! block!]][
	append log-list/data rejoin [now/date "/" now/time " " message]
	show log-list
]

If MESSAGE is longer than the width of the text-list MESSAGE isn't 
shown. Why this? The first two parts NOW/DATE and NOW/TIME are shown.

I expected that MESSAGE gets clipped

yeah, but it doesn't. .it just gets dropped from the display

That has been annoying me for some years.

Hmm... is there a simple fix, patch available?

I don't recall ever running into that specific problem before but 
I know that I've always done more than just SHOWing the text-list 
after updating its data...

Ok, that's a hint. So Ammon, what have you done? :-)) Shoot it?

What version of REBOL are you using?

Link

REBOL/Link 1.0.6.3.1 3-Aug-2002

text-list/update

Sounds like a wrapping issue in the iterated faces...
