[!REBOL3 GUI]

Cyphre

...because R3 already supports char! values bigger than 255 so this 
should work transparent IMO
Graham

did you ever figure out how to create GUI event from inside a network 
protocol?
eg. for the purposes of updating a progress face
Cyphre

[2496]
I did that in R2 so I suppose it works also in R3?
Graham

[2497]
How ?

How about a bounty for the text rendering?


To be honest I don't care to much about better quality at the moment. 
We need a way to display text and some formatting (which works) and 
special chars like Umlauts. That's good-enough for us to use R3 for 
commercial development. Optimal text-rendering is nice to have but 
invest to do it must be covered by some revenue first.

The bounty is possible - but who has the skills to do the real work 
apart from Cyphre? :-) And also - how many man-days approximatelly 
would it take? (research plus implementation).

Who knows how long it takes... anybody complaining about the look 
has a chance to find out.
Pekr

[2501]
that contradicts the bounty mechanism, and is typical example of 
bold opinion, which burries and always burried REBOL down ...
Rebolek

No it doesn't contradict nothing. I'm not against bounties at all. 
I'm just against people who complain that first version doesn't do 
everything they want.

Where's the link to the rich text dialect that Richard was talking 
about?

Graham: http://rebol.net/wiki/Richtext
it's probably a good idea to create a wiki page regarding all the 
discovered issues around unicode in View. that way, it's easier to 
create a community project around it.

bounty: This won't cover the total-costs, but it's an additional 
sponsoring from the community that Cyphre can work on it.

Graham: regarding the 'updating GUI from network protocol' question

I have found some older scripts I did and quickly added the progressbar 
to it so you should see how it works.
You can download it from here:
http://www.rebol.cz/cyphre/scripts/r3/net/client.r3
and
http://www.rebol.cz/cyphre/scripts/r3/net/server.r3


just run server and client on localhost and press enter in the client 
console to see how the server shows the progress of upload.

Cyphre, the server link gives a 404

AdrianS: give it another try...it is highly possible Pekr's Apache 
instalation on this server is bugged so sometimes the links works 
and sometimes not ;)
AdrianS

you're right - it looks like a fairly even split between good response 
and 404
Pekr
12-Aug-2010
[2511]
yes - still not solved problem of occassional wrong path dispatch 
of Apache in ClearOS :-(   .... Cyphre, you better put it directly 
onto rebol.cz domain ....

is R3 view coordinate system still using Y at top of window?
my guess is yes.


it would be nice to have a switch to allow this to be switched somehow 
within a drawing operation.  some gfx operations are hard to
adapt from normal vector math which uses Y values incrementing when 
looking up
especially if mixing in 3D stuff.
Graham

[2516]
The Y axis is vertical...
Maxim
12-Aug-2010
[2517]
but pointing down
Graham
12-Aug-2010
[2518]
0x0 is at the top left which I guess suits text .. but most everything 
prefers 0x0 to be at bottom left
BrianH

[2519]
The question is whether positive goes down the axis from the top, 
or up from the bottom.
Maxim
12-Aug-2010
[2520]
exactly.
Graham
12-Aug-2010
[2521]
I think it should be the other way around
Maxim
12-Aug-2010
[2522]
the issue is that reading starts at the top (in western writing ;)
Graham
12-Aug-2010
[2523x3]
text is going to largely computed by the view engine
going to be
so why make everyone else compute when doing graphs etc ??
BrianH
12-Aug-2010
[2526]
User interfaces are usually composed from the top-left too, in western 
cultures.
Maxim
12-Aug-2010
[2527]
its almost impossible to reverse layout when it is expected (and 
much easier to compose) going down.
Graham
12-Aug-2010
[2528]
Just thinking ... dBase used bottom left too
Maxim
12-Aug-2010
[2529]
but it would be nice if we could tell the graphics to use up or down 
on the fly.
Gregg

Postscript does as well.
BrianH
12-Aug-2010
[2531]
Composing UIs from the lop left makes sense when the UIs are specified 
using a declarative language that starts from the top left too, a 
language like REBOL.
Gregg

Can't you use a draw transform?
Maxim
12-Aug-2010
[2533]
even text rendering is more naturally understood looking up, from 
the baseline.
Graham
12-Aug-2010
[2534]
I think that's what Cyphre also argues .. to use a transform
Maxim
12-Aug-2010
[2535]
transforms cause all kinds of complicated issues.  it will also slow 
down calculations since its applied within the pipeline, instead 
of directly within the engine.
Graham
12-Aug-2010
[2536]
whichever gives us the greatest speed should be the one we use
BrianH
12-Aug-2010
[2537]
Is there a problem with having Draw gobs be bottom-left, but text 
gobs top-left?
Maxim
12-Aug-2010
[2538x3]
it won't make a difference in speed.   its just a questing of the 
order of rasterizing, start at bottom or start at top.
yes, the coordinates will be inversed.
unless that is managed internally, which is could.
Graham

TV guys like Carl start at the top
