[!REBOL3 GUI]

He's right. While:

	g: make gob! [draw: [pen red line 10x10 20x20]]
	g/draw/pen: blue
	view g


is fine for small draw blocks, it's a pain for example setting the 
2nd pen to a different color ... or moving a logical group of draw 
operations around. In reality you are quite often forced to dynamically 
regenerate draw blocks each time ... which forces you to split big 
draw blocks up into discrete gobs (e.g. one gob to draw a blue circle, 
another a red box, etc). This is an issue with draw not gobs (which 
have been very well designed IMHO).

Max continuead a bit:
----------------------

part of what I want to attempt for my host code work is to implement 
liquid and globs natively in R3.  with access to AGG I could build 
the single most powerfull canvas engine in any language...


 we'd have absolutely nothing to envy to ANY other language, not even 
 Apple's engine... as long as the AGG can render a few more things 
 and add filters to AGG strokes.


globs use AGG and allow events to be sent to individual AGG strokes. 
 so you can "slide" a single line by clicking on it. the cool thing 
is that the input mask and display are separate... and you can implement 
any number of layers per display element that you want.
The nice thing is, that all View code is going to be part of Host 
Kit, once View moves over to command! interfacing. So anyone experienced 
can experiment ...

I agree with Max on this. Hopefully he'll get to start on those changes 
soon along with Cyphre.

Yes, we want REBOL being an ultimate media engine :-) Do you remember 
Carl stating Multimedia is his second name? One point at the time 
we were even teased with REBOL/Media :-)

Getting a window plus event handler up and running only using View 
(no load-gui) is pretty simple. The code, for those interested, is:

	system/view/event-port: open [scheme: 'event]

 system/view/event-port/awake: make function! [[event][print event/type]]
	f: make system/standard/font [size: 36]

 d: make gob! [text: "Title" offset: 50x50 size: 300x200 flags: [resize]]
	append d make gob! [text: [font f "Text"]]
	append system/view/screen-gob d
	show system/view/screen-gob
	wait system/view/event-port

here is another version (more abstracted):

win: make gob! [
	size: 300x300
    draw: [
        fill-pen blue
        box 5x5 90x90
    ]
]

init-view-system

view/options win [
	title: "test"
	offset: 'center
	handler: [
		name: 'my-handler
		priority: 100
		handler: func [event] [
			if event/type = 'close [

    unhandle-events self ; Remove this handler from the global list.
				unview event/window
				quit
			]
			none
		]
	]
]

What sort of widgets do we actually have so far in the GUI ?
Is there a list somewhere?
cool... .. type "demo"
Is the way the panels are redrawn visibly a special effect ? Or something 
else?
The alerts don't focus on the "OK" so that you can use the space 
bar to dismiss them.

graham, if you have an account to the r3-gui world, there is a list 
in there
But... the list is likely to change. I hope some of my ideas will 
be added.
Graham

Henrik ... I don't
I'd like to start writing some test scripts .. but need a table widget/face/whatever 
...
Also a tabbed panel ...
Henrik
15-Jan-2010
[69x2]
there's only a single column list available at this time.
no tabbed panels either

R3 gui is supposed to be easier to code for than VID isn't it ?
Henrik
15-Jan-2010
[72]
yes it is, but you can of course not do so much, when there is only 
a small set of styles available.
Graham

I don't know anything about the intricasies of GUI programming ....
Does the text-list use a fixed font style?
Henrik
15-Jan-2010
[75]
No, it uses a standard arial font.
Graham
15-Jan-2010
[76x2]
Then I won't need a table yet if the font is fixed pitch
and are face iterators used for text-lists ?
Henrik
15-Jan-2010
[78x2]
Some things are the same as in R2: You still create layouts with 
a dialect and you still create styles, but style writing is more 
important now, since face hacking like in VID isn't possible anymore.
VID3.4 has no face iterators. Too heavy and unnecessary for GOBs.
Graham

Has anyone written any demos apart from "demo" ?
Pekr
15-Jan-2010
[81]
Graham - I think it is preliminary to use VID3.4 productively or 
to extend it. There are planned some design changes to happen ...
Graham
15-Jan-2010
[82]
I have noticed some instability.  If you halt from a GUI script and 
then try and close it ... r3alpha crashes
Henrik
15-Jan-2010
[83]
Graham, no other demos, but I have a lot of private ones, that only 
work with my styles. You have seen all the screenshots.
Graham
15-Jan-2010
[84]
How do you see the source for a style?
Henrik
15-Jan-2010
[85x2]
The resizing and aligning issues makes VID3.4 difficult to use for 
creating decent aligned faces. I would probably wait until that is 
at least fixed.
Graham, all available through R3 chat.

Ok.
so a text-list is now called a "style" ?
Henrik

#2686 and "get lists.r"
Graham

[90]
Hmm.. no messages in GUI in R3 chat for this year
Henrik
15-Jan-2010
[91]
they are all styles
Graham

How do I download all the files I see with 'ls ?

thnx
So, I guess I need to wait a couple of months ....
Henrik
15-Jan-2010
[96]
yes, probably a good idea
Pekr
15-Jan-2010
[97]
Yes, the result of constant "topic jumping" during the development 
:-)
Graham

Sigh ...
I presume I can change the font used to a monospaced font ...
Henrik
15-Jan-2010
[100]
you can, if you can find where the font specification is used in 
the list, but you want to create a new style that uses that font.
