World: r3wp

Shame about breaking vid compatibility .. there were somethings I 
could not do in rebgui so I would switch to using ViD in the same 
application.

For instance I use VID to do a print preview ... using a draw dialect. 
 Never tried it with rebgui

Yep, windows media player has a play button that toggles to a pause 
button.

hence no further ability to mix VID with RebGUI
 ... correct.
promise of 

much lower" memory requirements, but the opposite is true" ... not 
quite. A lot has been added, in particular 4 inline images, without 
noticeably increasing memory. Also remember that many of the improvements 
(reduced dependency on View/VID mezz code) will only be apparent 
when using RebGUI with enface/rebface (tour.r uses 13,817Kb under 
rebview here, and 11,223Kb under rebface). Lastly, reduced memory 
usage is not apparent with tour.r as it doesn't reuse a lot of the 
same widgets (i.e. tour.r is a good reflection of "base" memory usage 
not runtime memory usage). If I find the time I'll knock up an example 
that demonstrate runtime memory differences.

looks like the current version of RebGUI is highly matured

 ... thanks, I hope to have an "official" release with updated docs 
 by the end of September.

THAT is very cool news.

And toggle?

I'd like to see an option to use a vertical layout for request-value

is a pretty long requester.

 ... there shouldn't be any. Both VID are RebGUI are just "face factories" 
 ... feed them a spec and they produce a face object. All other functionality 
 is neither VID nor RebGUI specific. I get a lot of emails asking 
 "how do I do x in RebGUI", but 99% of them are really "how do I do 
 x in REBOL", or, "how do I use the SDK to do x" type questions.

I use VID to do a print preview ... using a draw dialect

 ...RebGUI's use of the effect facet (and hence draw) is no different 
 to VID's. Also note that 'draw is available as a native from the 
 console (i.e. you don't event need VID or RebGUI to use it).

And toggle?

 ... does it need to support more than two states? Does it need to 
 support text (like a button) and images (like icon)?

Well, I personally don't use icons for buttons ...

Just something like the VID toggle is fine for me.

different text and different colours for the buttons

more than two states is a rotary widget ...

BTW what's wrong with set-state [ block of widgets to disable ] ?

Ah, I confused the toggle and rotary widgets. OK, I'll add toggle 
(text button version only).

what's wrong with set-state [ block of widgets to disable ] 
 ... do you really mean set-disable and set-enable?

could be .. the function that changes info

options [info] was replaced with set-disable and set-enable .. and 
you can specify disable like this as well:

display "Test" [
	field
	f: field disable
	field
	button "Off" [set-enable f]
	button "On" [set-disable f]
]

I've been looking at the jqGrid ... http://www.trirand.com/jqgrid/jqgrid.html
and many of these grids use a data source instead of a static block 
of data.

(see why I'm keen to redo the docs :) )

why not just ... set-enable f true/false

with a data source you can let the pagination occur within the widget

And let the widget handle the "loading ..." indicators

What I do at present is use a tab-panel and have the loading gif 
in one, and then replace that panel with the table once the data 
arrives

Having pagination would really help a lot ... sometimes i have tables 
full of hundreds of items.

why not just ... set-enable f true/false
 ... makes sense, I'll think on that one
use a data source instead of a static block of data
 ... live data?

sql query

What do you mean by pagination in the context of a table?

say you have 1000 rows... but you only want to display 20 at a time

having all the data inside the table at once means big slow down 
time

better to feed the table from a sql query, or another function that 
holds all the data

so you can use the scroller to move within the 20 items .. but not 
to scroll past them.  You have to paginate to the next 20.

The slow-down is from the query side not the RebGUI/table side. Table 
uses an iterator function so whether the table has 10 rows or 1,000,000 
it should be the same speed ... fetching 10 rows or 1,000,000 across 
a network is another story.

That's not my observation.

Anyway, 20 rows will be faster than 40 right?

Anyway, scrolling thru 1M rows is impractical.

I presume altme uses an iterator function as well... I just switched 
from 1000 to 4000 in preferences and now scrolling is a dog.

Try this on 10, 100 and 1,000 rows:

d: copy []
loop 20 [insert tail d reduce [random 10 random 10]]
s: now/time/precise
display "A" [
	table 20x100 options ["A" left .5 "B" left .5] data d
]
print now/time/precise - s

seems to scale pretty well here (on a Mac).

(replace loop 20 with loop n)

Back to your request-value question, does the prompt for:


 request-value "Enter the url for your website here. It looks h t 
 t p ://www.site.com"


appear on 3 lines? If so, what would you enhancement request (vertical 
layout option) do? (not wrap the prompt and extend the field width 
to match prompt text width?)

the prompt doesn't wrap currently ...

I'd just want an after 1 layout I think

What build# are you running?

I tried your latest

as for the table scrolling ... yes, it is fast.

Did you change the table routines recently?

In my app, I have 24 rows, and there is a definite lag belween the 
scroller and what I see on screen.

ie. the scroller lags behind the mouse as it drags it up and down.
