World: r3wp

If someone has some spare time to spend, I would like to have some 
tests being done for following case - In our PC shop, we mounted 
big LCD TV for some message/advertising purposes. The problem is, 
that the screen is placed vertically. I wrote small news scroller 
script, which eats some CPU cycles, but is still OK and very simple. 
But - when I tried it on that vertically placed TV, it is practically 
unusable :-(  - too jerky. I would like to know, if it is a driver 
issue, or just another View kernel defficiency? Should there be a 
reason why it should be a difference in performance? Video works 
OK for example.


Here's the script to test - http://www.xidys.com/rebol/news-scroller-r2.r
, so if you are willing to mess with your PC settings, go ahead :-) 
(not sure your icon placement will persist ...)

there are drivers that will rotate the screen display.

I know - they all do. But I would like to know, if you will notice 
similar slow-down/jerkiness ...

did you try using the rate attribute?

no .... what do you mean?

An integer! or time! that specifies periodic timer events for a face. 
This is used for animation or repetitive events (such as holding 
the mouse down on certain types of user interface styles). An integer! 
value indicates the number of events per second. A time! provides 
the period between events. The timer event is sent to the face feel 
Engage function with an event type of time.

from http://www.rebol.com/docs/view-system.html

OK, I know - but why do you think it would make any difference? You 
are asking me to change it in order to do some fps tests?

added fps counter to the file. No difference for rotated display 
on my notebook, the same report received from Cyphre. So - it has 
to be some bad driver on the testing PC. Case closed (hopefully), 
thanks for assistance ...

Is there any way to detect where the mouse is after a double click? 
 I want to popup a menu where the mouse is ...

Graham, the engage function takes 3 parameters: face, action and 
event. The mouse offset in the face is event/offset. Then you have 
face/offset and face/parent-face/offset. Adding all, and you get 
the mouse offset on the screen.

ahh.. I wonder if I can hook into that in rebgui

visualisation,
does somebody knows how to create a map like this in rebol?

a qubic map:
http://gdmap.sourceforge.net/img/gdmap-preview.png

some more examples and radial maps of this are here:

http://wiki.ubuntuusers.de/Festplattenbelegung?highlight=verzeichnisserstell

A hint to a source, algo or raw concept etc. would be nice.

especial the calculation how to find and place to the proper position 
within 
the workspace is what I am looking for.

Have you looked at this paper?
http://www.win.tue.nl/~vanwijk/ctm.pdf

It's with explanation, algorithm and everything. Port it to REBOL! 
:-)

great geomol! exactly I was looking for.

I'm have trouble keeping an inform window in front of the parent 
window.

All otehr inform windows remain in front but this one will hide behind 
parent if I clcik on hte parent. 

All other modal characteristics remain - meaning I can not do anything 
in the parent until I close the inform window...

am I right that an INFORM window can't be used with INSERT-EVENT-FUNC 
or is there a way around that?

INSERT-EVENT-FUNC is inserting events in system/view/screen-face/feel 
while INFORM uses system/view/window-feel as window's feel object.

You can try hacking system/view/window-feel to process events from 
system/view/screen-face/feel like that (quick hack, untested) : 

svwf: second get in system/view/window-feel 'detect 

insert svwf bind [system/view/screen-face/feel face event] first 
pick svwf 5

hmm... I don't think I want to do that. I'll do something with view 
instead.

there is no window list for ordinary windows, like there is for INFORMs 
with system/view/pop-list?

system/view/screen-face/pane seems to be the solution.

Doc, it looks almost as if you are right, but I haven't gotten it 
to work yet, i.e. the feel for the INFORM does not respond like it 
should.

I've got this puzzling problem.  I have a function that brings up 
a rebgui window with some elements in it.  The elements are defined 
as local to that function.  The function is invoked by clicking on 
a table element in another window.

Now if I double click instead in the first window instead of single 
click to bring up that function, the named variables declared as 
local are now none!

If I don't make them local, but leave them as global, then there 
is no problem.

the double click action is an empty block

Hmm.  Doesn't happen in VID so must be a rebgui issue.

; I need 100 rows like these both samples with unshared data access 
for each row.

; I have also tried with stylize/master (panel with) to construct/compose 
a master 

; row like this but doesn't succeed. any change to make this work?


list-func: func [] [ layout/tight [across x: text "x"  y: text "y" 
z: progress 0.5   w: box 40x20 effect [ draw arrow blue rotate  60 
]   ] ]

view layout [
	a: box 300x50
	b: box 300x50
	do [a/pane: list-func]
	do [b/pane: list-func]

 btn "set a" [a/data: [x/text: "1" y/text: "2"  z/data: 0.8 w/effect: 
 [ draw arrow red rotate  180 ]   ]  show a ]

 btn "set b" [b/data: [x/text: "1" y/text: "2"  z/data: 0.8 w/effect: 
 [ draw arrow red rotate  180 ]   ]  show b ]

 btn "set"   [x/text: "1" y/text: "2"  z/data: 0.8 w/effect: [ draw 
 arrow red rotate  180 ] show b  ]
]

quit

or how to supply data to a standard list containing progress and 
draw elements like this one above?

view layout [
        below
        p-list: list 550x180 [
                across origin 2x2
                chk: 	check true 
		a1: 	text wrap 100
                a2: 	text wrap 100
		pg1: 	progress 40x20 0.5
		pg2: 	progress 40x20 0.2
		a3: 	text wrap 20
		arr-1: 	box 40x20 effect [ draw arrow red rotate  180 ]
        ] supply [
                if count > length? t [face/show?: false exit]
                face/show?: true
                face/text: t/:count/:index
		;; face/data: d/:count/:index
        ]
	
	btn "set" [ ] 
]

LIST doesn't iterate styles that need state (IIRC). I would generate 
the layout dynamically and put the whole thing into a scrolling pane, 
unless that ends up being too slow or memory intensive.

I agree. It's very difficult to make a lot of styles behave properly 
when iterated by a LIST. (And I've tried, believe me.) It's better 
to make a window full of real faces and scroll your data through 
them yourself.

thx for direction gregg and anton, will create a custom face for 
this.

anyone had issues with view popups when inserting a custom event-handler?


I'm doing something in view, nothing patched, wake event left as-is... 
I have an inserted an event-handler, and the moment I click on a 
choice, all the events stop... even time events.


I don't even receive events at my handler, so its not a "returning 
none from event-handler" type bug... any ideas, fixes, similar unsolvable 
observations?

this is mighty strange... doesn't seem related to the event handler 
finally... I commented-out that part of my code and the choice still 
hangs my app!

found it... related to some hierarchichal library loading... which 
inadvertently ended up loading glayout which replaces the popup handling 
by its own. so all is good... sorry for jumping the gun.

Is 'image-filter implemented in R2 ? Or is there another interpolation 
 means to improve the display of an image when changing it's size? 
Of course, I do not want to use external means like ImageMagick.

jocko, only for upwards scaling unfortunately. No, you can't make 
good looking thumbnails in R2. :-/

I am not looking for thumbnail generation, but for image display 
with rescaling with fractional zoom factor (let's say between 0.5 
and 2.0). When using effect resizing in a layout, the interpolation 
mode is nearest. Is it possible to set it differently (i.e. bilinear) 
?

I'm not sure the View engine supports filtering at all. The DRAW 
engine does for upward scaling, but not downward scaling < 1. I only 
mentioned thumbs, because it's a common scenario. :-)

ok, anyway,  to my opinion, it'a a must for the R3 engine.

R3 does this elegantly already: It's based only on DRAW and all options 
for filtering from AGG are exposed. It fully supports high quality 
down and upscaling. :-)

Nice ! Another reason to expect a close beta release !

Hey what are you saying, you can do the scaling you want  with Draw...

yes for the scaling,  but it seems that there is no interpolation 
(apart from nearest)

is there a definite documentation on the systray support in windows? 
 I have some working code (from Izkata) but I am wondering if there 
is more to the interface than what I am using.

an exhaustive code example could also suffice

I don't even think I used systray in REBOL since going to Vista. 
 So dunno if it works on Vista.

I would give you what I got but it is in archives as part of my easyserv 
project long ago.

anyone know how to change the system tray icon dynamically?  by this 
I mean... the winapi calls which play around with that?

can anyone explain to me why offset on para and font do nothing every 
I try to use them?
