So, it opens up the RebGUI window on clicking the button?

Yes

Graham: don't you have %user.r patched somehow?

My user.r is full of patches and when I'm not sure, where's problem, 
I rename %user.r to somethuing else to make sure I've got clean rebol.

no, I don't.

I'm going to try a new PC and see what happens.

REBOL/View 1.3.2.3.1?

>> rebol/version
== 1.3.2.3.1

Create a file called %test.r in view-root/public/www.dobeash.com/files/rebgui/ 
with the following:

	REBOL []

	do %rebgui.r


 view layout [text form system/version button "RebGUI" [display "" 
 [text "RebGUI from VID"]]]


and then run by double-clicking it. I see "1.3.2.3.1" in the text 
and clicking "RebGUI" displays the RebGUI window.

This is totally weird.

Your script runs okay.

I see the "RebGUI from VID" popup.

*BUT* if I run the same script from the console ... it does not work 
!

ie. if I type each command one by one.

do %test.r works

do %rebgui.r
and then 

view layout [text form system/version button "RebGUI" [display "" 
[text "RebGUI from VID"]]]
does not work.

You're not alone:

Script: "RebGUI system" (6-Dec-2005)

fails for me too!

so, I'm not crazy!!!

Even odder, creating a script with just:

	REBOL []

	halt

and then typing the exact same commands as above works!?

back later ..

what is the problem?

do http://www.dobeash.com/files/rebgui/get-rebgui.r
change-dir view-root/public/www.dobeash.com/files/rebgui
do %tour.r

if i do paste that, i get the tour running. (linux)

That works, it's the interaction of VID/RebGUI when REBOL is started 
in a certain way that's the problem.

Here too..

that halt-trick works here too. portable bug.

Maybe this:
probe system/script/header
do %scratch.r
probe system/script/header

yep.

view layout [text form system/version button "RebGUI" [display "!!!" 
[text "RebGUI from VID"]]]

foreach window system/view/screen-face/pane [
        if title = window/text [return]
    ]

default title depends on system/script/header. with the halt in a 
script, you have a real title.

better compare faces with 'same? then by title?

btw if i vidify rebgui, is there a chance to get it accepted? or 
do you insist on the api-clashes?

Not sure what you're discussing Volker. This part "text form system/version" 
is not necesary for the script to fail.

Ahhh...

do %rebgui.r
and then 

view layout [text form system/version button "RebGUI" [display "This 
is needed!!" [text "RebGUI from VID"]]]
works :)

What's the technical reason for this failing with no window title?

the foreach above is from 'display. if you have a window with your 
title already, it simply returns. the default title with no header 
(no script) is "" ;)

so, the bug is with 'display

Must be an optimisation :)

yes. a hidden feature :)

Perhaps back then Ashley thought that he would be saving memory, 
by storing a block of strings instead of a block of window faces 
?

(I'm not sure of his intent with this, though...)

It's an optimization that prevents multiple windows with the same 
title from being displayed. Quite useful in apps where you don't 
want someone clicking on a button multiple times and getting multiple, 
identical displays. I avoided basing it on face comparisons as two 
windows could be "identical" except for a single sub-face such as 
a timestamp. Must be working reasonably well as no-one has noticed 
it in almost a year. ;)

BTW, good spot Volker. As for your two questions:

1) If i vidify rebgui, is there a chance to get it accepted?


I'll except anything that makes writing a REBOL GUI (View, VID, RebGUI, 
whatever) easier. ;)

2) Do you insist on the api-clashes?

Not sure what the issue is here, please elaborate.

I guess he means the name clashes for select-colour, date etc. which 
you already have noted.

request-*

No, argument-lists for actions, init is a block in vid (i suggest 
a rename, init: [rebgui-init] and both are happy.) maybe some others.

some vid-fields supported, like /flags, /access. So that 'layout 
and firends do not crash.

means i have to patch nearly everywhere a little bit, although close 
to find/replace. Can do that.
