Ah, thanks

Ashley: yes, this can be noticable for really large frameworks...say 
with ten thousands functions and more. There you can gain few miliseconds 
with this optimization during the load time.

few milliseconds during the load time? Is it even noticable? :-)

that was my point ;) Well if you create about 1milion functions then 
you can gain for about 50% of time on my CPU during code loading(4seconds 
instead of 8). But I haven't seen a Rebol project with so many functions.(but 
I'm not saying it cannot be developed ;))

Q: Is it possible to create an app that at the same time reads two 
data/ports.

F.ex. load an image from net and at the same time read data from 
GPS and display it on old image?

use async for this

a simple "aktiv: wait[port1 port2]" would be enough, with open/diirect 
or open/no-wait. or such. Never remember what these all do ;)

So am I right:

I need to define before ports:

gps-port:  open ....

url-port: open ... ??? ( read  doesnot fit here?)

user-port: ??? also is needed 

and then loop with wait [ gps-port url-port user-port ] [
	do I need here to catch what port it is 
	and do apropriate actions
]

Gone to Async group!

That's right, READ and WRITE are like a wrappers for OPEN and CLOSE. 
 eg. 
	READ url 
is equivalent to:
	OPEN port
	.... copy data here ....
	CLOSE port

some-port: open/no-wait/binary tcp://something
forever[
 active: wait REDUCE[ gps-port url-port user-port ] [
  new-data: copy active
 ; new-data is some #{...}
]

and decide what to do based on active,
 if same? avtive gps-port[..]

there are also some automatics which accosiate a function with a 
port, but i find this way easier to trace to get started.

and then here is async, which is a bit faster. Because /no-wait still 
does some waiting for error-checks. for async you need a library, 
by gabriele, romano or DocKimbel. Or deep knowledge.

perhpas a silly question, but how do I determine the name of a function 
mi currently in ?

As in, Im creating functions with a random-name and I would like 
to know in what function-name
im currently in... Is this possible ??? Like a 'SELF or 'ME ?

Not officially. IIRC there is some trick with triggering an error, 
somewhere on the ML.

That's not easy to figure out.

Where to find some documentation about systray in Rebol?

rebol.com

http://www.rebol.org/cgi-bin/cgiwrap/rebol/search.r?find=systray&form=yes

Thanks - already found!

What I am missing is what else words I could use for tray controls 
and messages received?
F.ex.
Can I activate tray meny un left click?
Is it possible to make submenus for systary icons?

double click works for me

Cyphre is working on systray enhancements .. stay tuned

there is one bug found with systray :-( you get events only if console 
window is visible ....

This bug is not related to systray directly (ie the current Systray 
support works fine) but it is related to system port.

Regarding bug:

Script of Gabriele works fine for me even no console window is visible. 

Then the question is - does it (systray opeartions) affects other 
event waiting on ports (f.ex. interface events, loading file from 
internet)

Is it possible to change tray icon?

no at the moment

Iterated faces.  A good reference to look at?  The Wiki seems to 
be missing some helpful info

How to change part o f a color in gradient?
F.ex.

	at 535x100 box teal 30x315 effect [
		draw [
			fill-pen linear 0x0 0 315 90 1 1 red yellow green
			box 0x0 30x315
		]
	]


Now I have each color equal, but how to make so that f.ex. green 
is ~50%, Yellow ~30% and red ~20% of box?

This is not possible in the current version of DRAW. You have to 
'compose' more boxes to create linear gradients with different ratio 
of color spread at the moment.

Is it possible to rotate feels, f.ex. progress bar so that it will 
be verical?

Vertical

just change the size

so, progress 5x30 instead of 30x5

I need that progress color will go up!

Ah ok - I was just do not belive that unti testing mysefl!
;-)

Next question:
How to tell that text in 'area face should be auto wrapped?

These are all ways of specifying the same thing:
view layout [area wrap]
view layout [area para [wrap?: yes]]
view layout [area with [para: make para [wrap?: yes]]]

view layout [area with [append init [para: make para [wrap?: yes]]]]

and you can test a little bit faster by making the area nice and 
thin:
view layout [area 40 wrap]

How is about clipboard for last version of view?
Is it possible to insert in clipboard port image?

only text is allowed

I have a small problem regarding event handling in TOOLBAR: Each 
icon consists of an icon frame face with a pane that contains the 
icon image and a text face.


The icon frame face has an ENGAGE event set for highlighting, doing 
the action of the button, etc. The containing faces both have their 
feel set to NONE.


Now when clicking on either the text and the image, the event seems 
to correctly bubble up to the icon-frame face, but OVER and AWAY 
events correspond to the face in which the event occurs, which can 
be for example the text face. So if you click on the text face and 
then drag away, the click is no longer valid, even if the mouse is 
still over the icon-frame face, because it detects OVER and AWAY 
for the face, I'm clicking and not the parent face.


This causes some clicks to be lost if you are clicking at the edge 
of the text face and accidentally moving the mouse away from the 
text face, say, the space between the icon and the text which is 
a natural place to click.


I've tried using DETECT, but this is greatly inefficient, because 
it processes all events.


I've noticed that the standard ICON face in VID behaves the same 
way. which I think is incorrect. Is there a way to transfer OVER 
and AWAY information from the parent face?

view layout [i: icon "Hello!"]


demonstrates this: Click and hold on the text and drag towards the 
icon. Or do the same from the icon towards the text. The click is 
lost.

So the face hierarchy looks like this:

tool-bar
       |
icon-frame
      /  \
    /      \
icon   text


I would suggest blowing away the feels of the icon and text and do 
all your event handling in icon-frame/feel.
Is there any reason you can't do that ?

that's already what I'm doing. the problem is that the OVER and AWAY 
events seem to be from those faces with FEEL set to none anyway.

You're right, that's a confusing aspect of over and away events in 
the engage function.

I am quite positive I solved this before using a combination of feels 
somehow....
