Thanks .. I can work with that.

When drawing, I would like to translate the X to 0 and Y to ( Y + 
28 ). What the Matrix should be? Thanks.

I mean using the Matrix command in Draw, like MATRIX [a b c d e f]. 
The Matrix command would premultiply the current transformation matrix 
with the given block. What should I assign this block to translate 
the X to 0 and Y to ( Y + 28 )?

Forget about my previous question, I am not going to use matrix in 
this case.


For rendering cahracter images, I thought that relative-positioning 
could be a good idea. After drawing a character image, then shift 
(translate) to the next position, and the next character would be 
in the right position. So I made my draw block some thing like [ 
image char1-img translate rp1 image char2-img translate rp2 ]


It worked, but the rendering performance was slow, way too slow. 
So I go back to my good old absolute positioning. [ image char1-img 
ap1 image char2-img ap2 ]. No more "translate", no more matrix.

Do we need a "User Interface Style Guide"? It may be part of the 
wikibood. I came to think of it when revising some of my scripts. 
I often program the key "Q" to be used to quit my scripts. But maybe 
it should be <ctrl>-q to quit, like it is with AltME!? Then I thought 
about, if anyone of you has made a style guide regarding user interfaces 
in REBOL? REBOL/View is made for different platforms, each with their 
own style guides. Should we stick to those guides, so our scripts 
have to use different keyboard shortcuts on different platforms? 
No, probably not! A REBOL script should work the same across all 
platforms, I think. Then we need a "User Interface Style Guide", 
so us developers can stick to the standard when developing REBOL 
applications, shouldn't we?

*wikibook*

Geomol - such an userguide, would be usefull, because first all usage 
schemas would have to exist on the paper first. It would be clear, 
we first have to think, because it would be even clearer, that new 
VID without things like proper focus system, keyboard support, etc. 
- is a no go ....

I several times posted Gnome usage guide as a reference ...

http://developer.gnome.org/projects/gup/hig/

If someone make such a guide, it should be cleared with Carl, I guess. 
He probably has some ideas, and the wanted user interface should 
be within the frame of how REBOL work (and will work in the future).

I can't get this to work under OSX, so I want to know, if it works 
under Windows.

Does this example make the text position change when pressing the 
button?


view layout [button "Test" feel [redraw: func [face act pos] [if 
face/edge [face/edge/effect: pick [ibevel bevel] face/state] face/para/origin: 
pick reduce [face/para/margin + 0x1 face/para/margin] face/state]]]

it seems to change ....

Down one pixel? Try change 0x1 to e.g. 0x4 to better see the change!

yes ... I have small dot effect on my notebook LCD, so I moved text 
to align with it. I can see it really goes down certain amount of 
pixels

LOL this is really strange! I can get the text to move, if I change 
the position more than 0x1. 0x4 works, so does 0x2. Strange!??

Here under OSX, the text doesn't move, if I only tell it to move 
0x1. I'll report it somewhere.

it definitely seems to move even 0x1 under W2K here ...

maybe OS-X uses two pixel precision ;-)

or isn't kind of font antialiasing on OS-X, which can "blur" it?

The text is rock solid here when using 0x1. Using 0x2 moves it one 
pixel down.

geomol, noticed the menu bar in the viewtop? looks like it's the 
same thing.

the first item is sitting a pixel too high.

Just noticed. Weird!

Sounds like a font rendering bug.

wonder if the cursor bug is also related. on OSX the cursor is sitting 
1-2 pixels too far to the right.

Yes, and it's not just to the side, it's also a couple of pixels 
too far up.

geomol, here's another one.

view layout [area 400x400]


paste a large amount of text in it. place the cursor to the far right 
on the top line and press cursor down. the cursor also moves to the 
left.

It's a bit weird. I had thought, code to control these things were 
the same on all platforms.

anyone know the algorythm by which I can convert raw event/time values 
(an integer which seems to be in milliseconds) into a time value?

event/time is different when comming from the wake-event, it seems.

I need to skip events which are too old... my current event mungings 
work, but are hard to adapt as refresh slows down... having this 
time accurately would allow me skip events

If it's in milliseconds, try: to-time event/time / 1000

hum  good guess.

resize-image: func [
	dest [file!]
	size [pair!]
	file [file!]
	/local im
][	
	im:		load-image file
	save/png 	dest to-image layout [origin 0x0 image (im) (size)]
	im:		none
]

i use the above function to resize images but it leaks on 1.3.2.4.2 
 Am I doing something wrong or is it a bug ?

code looks good to me, though try: draw size [image im 0x0 size]

You might ask rambo group about it being a bug.

(notice you did)

I know it is preliminary, but maybe we should rethink button design 
:-) If you try following, there is some visual effect, you see small 
circles among buttons :-)


do http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=periodictable.r

... but maybe it is because there is zero pixel space amongst buttons

there's nothing wrong with the cirles I think

hey, - there is - they hypnotise me :-))

actually moving the space between the buttons to -1 might improve 
the visuals a bit

as long as they're not changing their color and radius, it's hypnotizing 
level is OK i think ;)

for the VID 2 (or better let's call it VID 3.0?), we should count 
with things like space for hilite and visual focus representation 
....

Rebolek :-))

Electrons should  jump randomly around, no? ;)

but nice app indeed, no?

yes

someone on ml suggested to turn it into plug-in version ...
