Any simple way to set a "field", or better serie of fields with the 
same style,  to  read-only  at  runtime?

Plugin sound advanced, so I did not examine,  I just started Rebol 
a month ago.

My programming style has yet  not adapted the Rebol style. It still 
feels like translating directly from procedural languages.
But I'll check the plugins.

I'm just giving those instructions a go now, using Firefox 1.0

Many changes occured on /View during 2004 and that's very good after 
a long period with no updates. What about 2005 now? How far is RT 
from an official cross plateform /View ? What will trigger the next 
new release?

Graham: yes, it's what I did after searching why all my riff-waves 
has unsigned big'endian data :-) 
- but is it a bug - or a documentation problem?

I've got one event that I am processing for timer events, and I want 
to start up another that shows a time elapsed.  But it seems I can't 
have both going at once ?

Is that a bug, or just a by product of the way 'inform works?

Vincent, I'd say that's a bug. I also found just playing different 
sounds (inserting different sounds that were only loaded once each), 
that the audio format would change randomly ! 8-bit <-> 16-bit, 22.05kHz 
<-> 44.1kHz etc... and the sound quality eventually degrades, obviously.

Graham, I'd say that's a problem of the inform system. Check out 
Romano's INFORM patch and WAKE-EVENT patch.

Pekr, those patches still have issues to be dealt with; they are 
very complex, affect a lot of things, and do not have a lot of discussion.

/window open a new window

/window/away is a window which behaves like a menu (disappears when 
user click outside)

s timer inside a layout problem, above ?

I never could get SHOW-POPUP to properly act like a menu so I hacked 
my own solution that may provide some insight for you.  You can find 
it on REBOL.org...  Dropdown.r

where do I find the docs for hide (like to hide a password typed 
in?)  I know I have read it somewhere...

it's just a line, isn't it?

hmm, i think i don't have the svg viewer installed here, i was able 
to open it with inkscape but maybe it doesn't support that? i just 
see a line.

if i click the link i get a file download

isn't that a bit too blurry?

anyway, looks like the same graph rendered twice to make a blorry 
shadow

so you can render it, use the blur effect, and render it again with 
a small translation

Shouldn't be too hard to get a nice result in View with AGG.

I was just playing with the q-plot, and the output seemed a little 
plain ...

>> date-data: [ 1-Jan-2005 2-Jan-2005 3-Jan-2005 1-Dec-2005 ]
== [1-Jan-2005 2-Jan-2005 3-Jan-2005 1-Dec-2005]
>> y-data: [ 1 2 3 4 ]
== [1 2 3 4]

 view quick-plot [ 800x300 x-data [(date-data)] line [(y-data)] x-axis 
 6 ]

which draws a very straight line.

Hmm, that's from a while back (my first RF logo :o)  Allen has the 
keys to the archive...

I got the impression Joel used a Mac ..... and hence no Native View 
or AltME

Graham: re quick plot - yes, I had to make some changes to be able 
to draw xy graph with irregular x values. Unfortunately I didn't 
correct the behaviour for dates. I will probably include XY graphing 
capabilities into  my spider.r, because the "philosophy" of q-plot 
looks a bit "flawed" to me - it is "two-pass" (acceptable) evaluating 
expressions twice , which looks

Ladislav, do you have a fixed version of q-plot for irregular x values? 
 I can use seconds instead of date values.

Graham. I stopped developement of agg_lite.dll and switched to AGG 
v2.2 library which is used in Rebol/View alphas. The agg_lite.dll 
was just a proof of concept.

I'm using internally for testing and debugging 'a clone' of the same 
code(which is written for View with agg) as a .dll. But this version 
is not in state of public release.

I've managed to write a script that generates SVG line graphs that 
look like the one referenced above :)

generates a SVG graph of size 1000x1000, and scales the data automatically

that's a nice looking graph if you ask me.

Looks like your BP was a bit crazy when rebol2 went down :)

I think I should change the code a bit .. as if all the readings 
are distributed near the top of the y axis, then the bottom of the 
graph looks barren.

what does translate 2x2 do in agg-view?  Does it add 2x2 to each 
point until ..a new pen is used?

Hello, I'd like to create a data window like the one you're looking 
at now. This isn't an "area" gadget is it? I've created a "list" 
out of an area but each row is the same height regardless of content 
and it crashes a lot if I try to scroll the individual rows. Any 
suggestions?

Maybe a box like this:


>> l: layout [b: box white font [size: 12 style: none shadow: none 
color: black] "text text text text text text text text"]
>> b/size/y: second (size-text b) + 4x4
== 34
>> view l

so, this little server waits for commands, and then either browses 
to the required page in an iframe, or, opens up a new tab and puts 
the page there.

There might be a way, but probably you can't rely on this technique, 
with browser security being what it is.

That's a good sign.

Do any of the demos work?  ( http://www.compkarori.com/reb/) is 
a working demo ...

anyon can tell me how I can fix a web page containing a rebol plugin, 
so it detects the vertical size properly?

talking about saving files in the plugin... I did a simple (very) 
test... 

rebol [] write %test.txt "test"

ran that in the browser and then did a full disk search and I never 
found One file named test.txt  :-(

try a    alert mold what-dir

but if the plugin had a properties page, we could allow some scripts 
domains or ip addresses specific rights.  all set to off by default. 
 and all prefs values encrypted when saved of sent to registry, so 
that no virii or other nasty can allow its site to run unhindered.

Yes, and simply restrict the filesize. Or  better use an virtual 
filesystem, like a  zip.

but so far I am getting no results... and unless someone steps in 
to explain to me how I can write stuff out (read as gives me an example 
snippets which works on their machine)... I won't continue trying.... 
I've got other things to tackle first...


and obviously in normal web dev, the server is the file store, so 
you'd speak to it using http get and post... so as long as you have 
access to adding hooks on the server too, you can work out a virtual 
disk system through your web server... more safe too.

you can call javascript and  get back a string AFAIK.

But byreloading a div?

Our designer. Played a lot with the plugin IIRC.

Hmm, every demo I've tried using a fresh install has issues of some 
type or another.. trying to decide if this this is alpha, or beta 
at best?

has anyone succeeded in embeding the plug within a div which is persistent 
 or resident in some way (like in another frame, or something) so 
that browsing the same page twice actually just shows the previously 
launched plugin (so as to not have to actually restart it everytime...) 
???


I guess this is not just rebol pluging related, as the same effect 
would be desired for a flash based plugin too.

is there a way to store web content in another frame and swap it 
on demand?

Its been a long time since I've played with javascript... so I'm 
not only rusty, I'm shut. ;-)

Hmm....  You could probably just store it in a string and swap it 
in and out of a DIV tag.  Usually much easier than messing with frames.....

yes its possible, the boot sequence of REBOL seems a bit hard to 
manipulate...

I really wanted interactive dos shell session...  :-(  but that meant 
a little bit more code to detect if we where *in* a dos prompt already 
and doesn't seem trivial as per Carl's explanations.

not patching this simple issue was a bit of mistake imo ... community 
could put xy interesting demos online. But it is not worth it, if 
99% of corporate ppl are behind the proxy.

There is a 2.6.2 release that doesn't say "Beta" on it, but I don't 
know if that qualifies, as there may still be some issues, depending 
on how you want to use it. I'm using it, knowing there are limitations.

I want to use it to show a narrated slide presentation on my web 
site. Can it safely be used for that?

I haven't used sound in it, but a slideshow should be safe. If you 
already have a desktop version of the app, it should be easy enough 
to set up a page to try it under the plugin.

and because it took me some time... there is this important difference, 
if you center faces inside plugin:
;system/version == 2.6.2.3.1

center-face: func [
    obj [object!]
    /with face [object!]
][
    if none? face [face: system/view/screen-face]
    obj/offset: max 0x0 face/size - obj/size / 2 + face/offset
    obj
]

;system/version == 2.7.5.3.1
center-face: func [

    {Center a face relative to parent (screen for windows) or a sibling 
    face.}
    obj [object!]
    /with "Center relative to a sibling face." face [object!]
][

    if none? face [face: any [obj/parent-face system/view/screen-face]]

    obj/offset: max 0x0 face/size - obj/size / 2 + either with [face/offset] 
    [0x0]
    obj
]

I did not expect it ... so we don't have proxy here ... hmm ... the 
proxy problem is a pity, because other than that, we could already 
use plug-in ...

there is just a problem that if I drag the window outside, there 
is no chance to get i back... only reload:)

the plugin itself has nothing in common with rebol - it is just a 
wrapper, and latest incarnation of plug-in was able to handle multiple 
instances.

I hope plug-in wrapper is open-source too. Tighter securite is something 
I agree with (after long discussion of Anton and Brian I believe 
it is a necessity). The idea was to limit amount of plug-in writeable 
data to disc, amount of max windows opened, etc., and to have certificates 
based aproach. You would buy certifikace and hence could develop 
full fledged apps with SDK.

what I can see a problem still, is, rebol "windowing". We use dialog 
box aproach. If I have window embedded in plug-in, and want to raise 
requester e.g., it will pop-up, and hece could be blocked. That is 
why I suggested, that maybe VID+ should think of native rebol windowing 
... not sure what others think about it ...

I really think the current plugin has its uses, its very cool to 
have an unrestricted plugin for some applications.  but a more protected 
environment would be much easier to disseminate at large.

imagine people's eyes when they will see they can have two browers 
speaking to each other without the need for a server!

hi guys, I can't find ANY example of calling javascript within the 
plugin !    can any one just give an example where I get some values 
from the DOM (I'd like to retrive the current URL from which the 
plugin was called, so I can talk to the server... a tool I built 
needs to be setup for each site... (without changing the code... 
its compressed.)

maxim, I made this a long time ago, shortly after the first plugin 
came out:

http://hmkdesign.dk/dom/curvyclean.html

http://hmkdesign.dk/dom/<-- all files can be seen here

a ha... do-browser  :-)

a ha... just figured it out... simply put the variable as the last 
thing in the script:

rebol []




view layout [ button "test" [view/new layout compose [vtext (do-browser 
{var url = document.location.href; url})]]]

the above will show a small page which has a button... click on it 
and the current URL is poped up in a new window  :-)

yippee!

I was playing around with some of the Demos for the plugin. They 
were working fine and then I got hte request to download the active-x 
component. I downloadred thing perhaps I had an older version installed 
but now the plugin is not working. I get a REBOL/VIEWdll window with 
"Show on face in closed window." printed inside. Anyone?

I downloaded version 7 of he cab file. All the demos point to version 
5. 

You should not need to go serach for a new version and manulaly delete 
old versions.


The docs also state that if there are version #'s in hte rebol head 
of the app the plugin will aluto update the cashed version if a new 
version is pointed to. I can't get this to work. Is this working?

I just discovered Tim Wylie's Wrapper for the rebol plugin. It works 
for FireFox3 Google's Chrome and Opera. It allows you to have multiple 
rebol apps running in seperate draggable windows inside the browser 
window. I tried it on opera mini and although the "dock and Application 
laucher windows show and app windows open the apps do not seem to 
run. I'm not sure how the wrapper works if its on the server side 
or client side. It worked on a fresh install of opera without me 
downloading the plugin dll (but it may have been there from a previous 
experiment.) 
Anyone know if opera mini could run this?
This could be a great way to get rebol apps on my mobile phone

You would need a rebol dll for the operating system and hardware 
of your phone. If it is not running Linux you may be out of luck, 
and if it is you would need to request a build. The WinCE build of 
REBOL is an old port of /Core for the handheld pc version of WinCE 
with no support for onscreen keyboards or Smartphone edition, and 
there is no build for Symbian.

If I use the paint program in the library ... as a plugin

I guess my plugin code will have to pass the image as a parameter 
to the code so that it loads the image.

the fax is on a remote site and will be converted to png by imagemagick

What I am doing now is storing the image in the webapp public area. 
 I think create the embed object with a parameter pointing to the 
image.  the embed object loads the paint program and then loads the 
image as the parameter.

That's the term Cheyenne uses for a password protected area of the 
webspace

did you need a password to draw on it?

let me do a quick video

the paint is a bit sluggish :(

I'lll give that a go.

the browser makes a nice container though allowing me to scroll the 
paint applet

graham, i think i remember the pluging getting a lot of mouse events 
(more than the standalone view). i think this was a IE thing.

Is there a reason to remove them? Adding a note about compatibility 
would be good, but removing them means losing a bit of reference 
material. I don't know the last version of IE it works under, but 
I actually have some old things that use it. I still have IE6 here 
for running those. :-\

Thanks.


I've tweaked the code so the plugin links are only visible to logged-in 
members; similarly the plugin will only attempt to run if you are 
logged-in. So casual visitors will not see it.


If there is ever a viable plugin for modern browsers, I'd be happy 
to reenable the public links.

Wow that is really cool. I downloaded and tested under Opera. Works 
very well.
Just a few notes: bubbles takes too much cpu time,

And gfx effect crushed (Opera hanged) when I tried all the effects 
then back to Invert (the first one)

Yes, bubbles take a little too time the first time it's launched, 
but it's very impressive,; so I put it first.
If you want more scripts, just email me: [maxint-:-tiscali-:-it]

Following wiki article claims, that there is only 15 functions needed 
to produce a plugin interface. I wonder - with R3 and extensions, 
wouldn't it be "rather easy" for a C skilled person, to create a 
R3 plugin for a plugin? :-) 

http://en.wikipedia.org/wiki/NPAPI

I asked Carl to free plugin source several times, sadly with zero 
response each time I tried. I think that plugin was not part of RT's 
revenue stream, so it is a pity it never happened, as someone could 
pick-up, do some fixes, improvements, etc.

There are a million things that are rather easy for a C skilled person, 
and that's the problem: there are fewer C programmers than tasks

I just wonder, if R3 could be made a DLL too? We have R3 core library, 
and the hostkit sources. Then we have rather powerfull extension 
architecture, which could serve to link to plugin library. Having 
R3 available would be much more interesting imo, as it has new gfx 
core.

Ah, need to put the files directly in the Application folder (I had 
created a Plugins folder first).
Thanks Alan.
