xml_charts looks interesting but doesn't seem capable of doing what 
I want.  But it might be useful for a website.  Does it do time series?

You'll have to check out all the examples to see it it does.

Has anyone ever seen a view app with several fields and and an area 
 that always minimizes when you hit the return key? In this case, 
I don't want it to do that. I  don't think I' ve ever seen that except 
in this app. What would make it do that?

not sure what you mean. is it like a panel that collapses?

It's actually a contact/address book based on Carl's rolodex ap. 
Basically, where ever you are in interface, when you  hit return 
it minimizes the screen as if you hit the minimize button. Weird.

Graham... Check out http://www.maani.us/xml_charts/index.php?menu=Gallery&submenu=Floating_Bar

If it's a custom app, they could be grabbing the enter key and minimizing 
it. But that seems like a really bad idea, so maybe just a glitch?

James - those aren't time series from what I could see.  Time series 
are fed date values, and are not just equidistant points on an x 
axis labelled with dates.

What was that presentation software that RT used to use ... presenter 
or something?  I'm looking to include educational software inside 
my app

You mean the script that turned Make-Doc documents into slide presentations?

That one was called %show.r and I think is likely available on an 
IOS server -- Developer?

There's a version packaged with Carl's devcon 2007 presentation:

http://www.rebol.com/article/0335.html

Wasn't there enhanced features in this version?

I think so .... I suspect Cark added all the features he needed to 
do the presentation he was writing that day :-)

Carl's latest causes a stack overflow for me

I think it was written by Sterling or Jeff

Pekr will know ... I'll wait for him to wake up!

found it .. http://www.cs.unm.edu/~whip/make-presentation.r

someone should snag it for the library

presentation?

There are two things - the one comes from Jeff  Kreis, and is called 
presentation.r, size 11048 bytes, the other is Carl's slide show 
presenter from DevCon in France IIRC, called show07.r

both of those script run fine here ..

Ah, yes -- I turned that one into a VID style...

I ran show07 on the first script from Carl and after repeatedly using 
the down arrow, it came up with a stack error near the end of the 
presentation.

I am unsure is it the View problem - my app is eating system resources. 
F.ex. when it is started in task manager it shows near 10mb memory 
use, but after a working day it shows around 70mb and comtinues to 
grow up.

I checked my variables, but it does not seems for me, that some of 
them are not releasing data. But probably I am wrong.
Are there some routine/trick how to trace/debug such situation?

My applications is doing some database checks and if finding certain 
data , then sending e-mail and/or sms.

There are some bugs in View that causes leaks when using networking 
and GUI events at the same time. That's only a very rough description 
of the problem. There are more accurate descriptions of this problem 
in RAMBO.

I had a similar issue with a small database server GUI. It continually 
ate memory until it was at 500 MB. Then I rewrote the application 
to be /Core only and memory usage was as it should be (way below 
500 MB).

stats ?

I'm trying to use Antons' Scroll-panel style but I'm having some 
trouble. 
Do you "do" the script or it it more involved? 

I tried to follow his style-gallery.r script but there is a lot going 
on in there and got lost. 
I see some kind of "include.r" script. perhaps that is needed?

Are there workaround the problem with view memory leaks (when using 
networking and GUI events at the same time) ?

not other than trying to avoid the specific cases that are in RAMBO. 
that might be hard, though.

What I found was - RAMBO Ticket #3593.
Is it that case?

I have simple interfaces, that normaly is unviewed, but I have tray 
incon. And in background there is two database connections.

Yes, that's the one. There are other leaks as well:

I got scroll-panel working. I think it was some conflict with cypher's 
tree style which I was also using.
On a related topic...

Is there a way to scroll down teh panel programaticly. (ie: give 
a y axis location and have hte panel jump to that spot) like a link 
on  web page?

And since Cyper's tree widget does not work with Anton's scroll-panel, 
any other tree widget's around?

set the offset/y and then do a show

Thanks. I played around with offset but I did not get it to work. 
Ill try again. 

Is there a way to find the offset for specific text in the panel? 
For example -so a search for a string and get back the location in 
the panel?

dont' think so

Still working with Anton's Scroll-panel...

I found a way to "index" the text location in the scroll panel as 
I build the layout. But when I try to set the offset to a specific 
position in the scroll panel I offset the whole "face" and not a 
reposition of the scroller. 
Example- 
I set my_scroll_panel/offset/y: 200

I feel I should be setting the scroller's value but I can  not seem 
to figure out how...

I got it to scroll to my index point but I acn't find the fuction 
to update the scroll bar.

Got it!
my-scroll-panel/access/set-scroll-offset my-scroll-panel 0x-100
After trying every combo!!!

was the accessor scroll-panel ever incorporated into any vid widget?

I got Cypher's tree widget to work with Anton's scroll-panel...sort 
of. Problem was tree widget uses cypher's scroll-panel style which 
of course works diferently from Anton's. Now I'm forced to use both 
and the tree scroll-panel does not display sliders correctly. 

I'm going to either need to find a way for the tree list to use Anton's 
scroll-panel or add the extra functionality to cypher's scroll-panel 
style...or start from scratch.

New problem with Anton's scroll-panel style. 

When I select text I loose mouse scroll-wheel use and Keyboard scroll 
functionality.


Altme does not have this problem. I guess it's inherent to the style.

sounds like a focus problem

Yes. I tried a feel/event function to trap the up event on the mouse 
and it restores my scroll functionality but I'm not able to highlight 
now!

Should I look to patch the style or place the fix somewhere in my 
code?

I'm able to re-focus the scroll panel within my "clip" function (to 
save the highlighted text) but if I just click in a text area or 
highlight and not save it using hte clip function I can not get scrolling 
back.

I have a similar problem re: scrolling, and I've tried the suggstions 
by amacleod without success, here I've copied a modified version 
of cookbook-scroller in the hope someone can suggest a solution.Hi, 
I'm trying to write a data entry form with many fields, this form 
is longer than a typical
monitor viewing area.

Creating the form is easy, but I cannot work out how to scroll the 
whole form 'up/down'

when the user TAB's out of the last showing field bottom and display 
the 'hidden' fields.

Rebol actually does TAB to the next field and accepts data entry 
but you cannot see it
without manually moving the scroll slider.


How do I programmatically make the form 'move' up/down ? and sync 
the slider ?

 I've tried "all" the example code I can find and none seem to do 
 the trick :-)


In the attached (modified cookbook-scroller.r) program I've added 
a few fields to illustrate the

problem. My need is for rapid data entry and using the mouse is really 
not a option, The program accepts user data, user TABS to navigate 
to next field, form slides as necessary, upon last field, data is 
saved, form cleared, cursor placed at first field, data entry continues.

Thanks for any ideas.

;; ============

You will need to know the offset value of each face you tab into. 
You will also need to detect which ace is currently focused. (Do 
not know how is is done).

If you know these two things you can set the offset and "show" the 
face to junp to that location.


Also, I do not know if all faces can be tabbed into such as your 
month list face..
