the looks are just a VID skin, you can very easily change that...

Ok, uploaded a new version

do http://anton.wildit.net.au/rebol/doc/proportional-resizing-example.r

the wrapping is neat :-)

So, starting small and increasing the size, you can see the buttons 
have a "compressed" state (hard-min), and they stay compressed until 
the location field reaches its min-size, which is the size at which 
the field has "enough" room for most normal location strings. So 
the field has reached its "preferred minimum" size.

Increasing further, the buttons expand to have enough room on either 
side of their text for some nice visual padding, but they don't need 
to get any wider. It is preferred for the field to get all the space.

Maxim, the problem for me with GLayout is the "and much more...", 
if only because it will take me longer to understand it.

its very simple, really...

but I do understand your point.

I think it's better to be modular. But anyway, maybe you could make 
a small demo which shows how each of Glayout's parameters work:

min-size, def-size, init-def-size, manual-min-size, static-size, 
elasticity, stretch... and any other I do not see.

although having someone like you on the wagon would help cleanup 
GLayout itself... Using it for myself has ironed out many little 
issues in the latest week... I've added some new facets like margins...

as I see your demo I see how these two approaches are similar, in 
many respects.  although I don't have a preset max size...

the way GLayout is built is that it just adds a few hooks where you 
can implement the calls themselves.

the actual attributes are style specific.

so you could implement your hpane directly within GLayout, but you'd 
have an automatic way to call the resizing, for example...

but anyways, I understand that at some point we'd have to get a few 
hours so I could explain (and then document the discussion) on the 
basics of those hooks.

Well, for a start -  replace/all read %glayout.r "self/" ""

I've already implemented henrik's toolbar in about one hour

and added a pop up to select icon, or text or both right on the toolbox 
 ;-)

those are details to improve readability.

you are free not to use self in your own code... but I can say that 
the 1 micro second which is spent  to look up a few hundred self/ 
 is nothing when compared to displaying 20x20 pixels of draw.

just ONE field with a linear fill in AGG, I have discovered, will 
bog down the whole display!

in normal view we don't notice as much because its static... but 
when you start adding dynamic resizing and real time scrollpane movement... 
its just sooo slow ... so much that I added a property in the field 
to remove all the prettyness!

so that large GUIs didn't become unuesable.

but I'd be happy to go over the engine with you in another group... 
(just to reduce the noise)

but hey if the above replace is a big turn off... I guess I could 
remove most (probably all) occurences of self/

Sorry, Maxim, now is not the time, I am afraid I must attend to other 
things.

no problem, meet me in the glayout group in a few days?

According to the DRAW Document, the shape is closed automatically, 
i.e. as a polygon, unless you specify a move command at the end of 
the shape block. However, the following example is different. why?

Never mind my previous question, I've just realized what was wrong.

What was it?

Jerry, you can also optimize the line segments a bit by replacing, 
eg:
	line 10x10 line 20x20
with
	line 10x10 20x20
I think this should be more speedy.

Anton, the shape dialect was generated by my REBOL script. So it's 
not easy to optimize it. I wrote a C# program, which get all the 
glyph data of Chinese characters. I put these data in this format 
: x y type x y type ... where type is the type of the point. My REBOL 
script loads the glyph data, and generates a Shape dialect for every 
character.

>> blk: [line 10x10 line 20x20 curve 20x20 line 30x30 line 40x40]
== [line 10x10 line 20x20 curve 20x20 line 30x30 line 40x40]

>> parse blk [any ['line pair! here: 'line (remove here) :here | 
skip]]
== true
>> blk
== [line 10x10 20x20 curve 20x20 line 30x30 40x40]

Gregg, there was a MOVE command, that's why. that was my mistake.

I look for 'line followed by a pair! and another 'line, then I remove 
the second one.
Actually, here is a better one:

parse blk [any [pos: 'line some pair! here: 'line (remove here) :pos 
| skip]]

Anton, thank you. Maybe I should prevent this situation during the 
code-gen, that could save some time. BTW, according to my observation, 
the situation is not common though. Most Chinese character glyphs 
are extremely complex, it's not frequent to see one LINE command, 
not mention two LINE commands together.

For you to have a taste of how complicated the glyphs of a Chinese 
Character can be, The following example shows the last character 
in my Chinese name. there are 238 CURVE commands and 7 LINE commands.

wow ! makes a nice glyph output though.   so this equates to  "Tsai" 
 ?

That's cool!

Wow, indeed! That's very cool Jerry.

I immediately saw a very easy way to condense all of that for in 
ram memory reduction... I'd use a dialect to convert to/from binary 
byte code... it would greatly compress the data... probably a 5 to 
1 ratio !

what about storing differences instead of absolute coordinates?

I don't that is even needed.

since all values are within one byte.

it could probably be done, but it's not worth it without slowing 
it down a lot. I wonder how coords are stored in fonts normally.

that depends how much ram he is using... at some point the GC slows 
down soooo much that speed exponentially decreases.

I wasn't following how the data block is generated. was that with 
a C# program?

Anton, the shape dialect was generated by my REBOL script. So it's 
not easy to optimize it. I wrote a C# program, which get all the 
glyph data of Chinese characters. I put these data in this format 
: x y type x y type ... where type is the type of the point. My REBOL 
script loads the glyph data, and generates a Shape dialect for every 
character.
