Graham some indulgence please menu in rebgui are very alpha stage 
vefor sunday I don"t even know  what could be the result of having 
it to rebogui and if it was workable with older non AGG capable rebol/view 
;)

hehe .. not complaining, just asking ..

when I see it was relatively close in code motion to rebgui I started 
to wanted hardly to port it and better it a little (the famous lefted 
option ... to quick developed to convince every one  ;)

GRaham you point to good problems any way ;)

the ask is do we need to specify in hard coded way the resize of 
every image ...

or do we let user size it's image be it self ?

img: to image! make face [edge: none image: img size: 22x22]

hum hum  I saying craps ... the image is hard coded sized but maybe 
to big ...

Previous images were 18x18, while I'm using "standard" 22x22 ones. 
Everything else needs to be resized accordingly, but it's going to 
be hard-coded so a lot of the dynamic sizing code can go. Less is 
more. ;)

:)

hey ashkey good to see you online at the same time than me

;;)

I was looking too it ... to see if we could only deplace to left 
the text  un menu popup

graham's menu problem patch

insert tail sub/pane make item-f [;menu item
						type: 'item
						text: itm
						offset: oft
						root: sub

      font-colors: either dis? [[172.168.153 172.168.153]] [font-colors]
						font: make font [align: 'left color: font-colors/2]

      para: make para [wrap?: false origin:  22x1 + (lineh * 1x0)]
						size: 0x2 + get-tsize/fnt itm font

starting line 132 just copy the para: value of item-f

The icons look about 20% bigger than the ones used in Trillian .. 
which I just downloaded.

hum

with a little  modification to para:  arround line 132 you can use 
both witout any over showing of text problem

para: make para [wrap?: false origin:  22x1 + (lineh * 1x0)]

can be para: make para [wrap?: false origin:  15x1 + (lineh * 1x0)] 
if you prefer

it's the first parameteer of para/origin: that needs to be changed 
;)

know what next task is a true challenge making tables in the style 
of GUI4CLI ... I'm affraid to turn mad ;)

this code sample show how multi column tables are treated using Gui4Cli 
;)

I think the menu code to popup menu must be retake in part to make 
the dropdown item alowing to put to it text + image icons :)

area style: Is it possible to add ctrl+cursor-left/right to jump 
over words? This would be nice and makes the area style mostly complete.

tabbing: How about a tabbing for "forms" and a tabbing WRT group-boxes. 
CTRL+TAB could jump out of the group box to the next field/group 
box and SHIFT+CTRL+TAB would jump backwards.

led: IMO it would be nice to have the same click-awareness as CHECK.

splitter: adding a richt-click to reset splitter to original position. 
If users have screwed up their layout ;-))

tab: IIRC someone state it already. A scroll-able tab-heading.

BTW: I'm just posting what I recognize while playing around with 
the TOUR. Great work so far!! Really looks very nice.

tab / group: Is the DATA part realy required as a structural element? 
What about this?

tab-panel [
	size 1000x300
	"Tab1" [...]
	"Tab2" [...]

The idea is to implicitly add a tab for each STRING! BLOCK! pair.

I never really like the implicit usage of FACE and other words in 
VID. Especially if not documented and those words are not very obvious 
to guess. I see that RebGUI uses the same approach:
	slider	[action [show-data p face/data]]

What about this?
	slider	[action [show-data p slider/data]]

This shows what kind of object we (implicitly) use.

slightly OT: With all those widgets now. Where is VID still "better" 
than RebGUI? Are we are missing anything?

Robert: VID isn't better imho.

:-) Ok, now I know what to use for my "new" projects.

Isolation/encapsulation of particular styles (widgets) functionality 
may mean simplyfying the situation, as we can see with RebGUI, althought 
it is not as feature (widget) complete as VID is ...

Rebol is so much free-form, that with something like VID, componentised 
(shared) feels, etc., you can get yourself into trouble and VID starts 
to look like a bit bloated, although it is really to say such thing 
about anything rebol related ...

What I am really pedant upon is proper system-like "behavior". I 
mean mainly keyboard .... I would like RebGUI having good tabbing 
functionality, even nested one (although now I don't know if other 
IDEs you program your apps in allow it, but imo yes) - imagine having 
table/grid on your screen, but also few fields and buttons. I want 
to shift focus to grid, and then I want arrow keys, insert, delete 
key to work in terms of grid, not whole form. Then there should be 
kind of "escape key", which will jump-off the grid and focus will 
be on whole form ...

Dunno if I am clear about what do I mean, but maybe ability of getting 
focus to group-box should be enough, it it provides focus isolation 
described above ....

 1) Widget observations: all noted. LED is the read-only functional 
 equivalent of 'check used for things like system status displays, 
 etc

 2) Tabbing (basic version) is slated for 0.1.8, more advanced features 
 will have to wait until the base widget set is complete.

 3) DATA is a required structural element to ensure widget specific 
 initialization is performed by init *not* the display function.

 4) Implicit face usage has two big advantages: a) allows you to cut 
 and paste code between widgets; b) different widgets can share the 
 same code.

 5) RebGUI still lacks a few of the more complex list / table / menu 
 / treeview type widgets.

 6) Re: new projects. RebGUI is still ALPHA and the basic design may 
 fluctuate as the requirements of more complex widgets becomes clearer. 
 I wouldn't be building any commercial applications based on it quite 
 yet (not until it goes beta at least).

 1) Also remember that VID was created against a much earlier version 
 of View, and that it is only recently that View functionality has 
 stabilized. One example of this is the extensive use of 'draw by 
 RebGUI compared to VID.

 2) Tabbing, like key mapping, is less of a technical issue than a 
 convention issue; but my aim is to be able to "drive" all RebGUI 
 widgets both with and without a mouse (although the priority is to 
 get the mouse behavior right first).

Once widgets get more complex, will they share any code, or will 
there be strict encapsulation, so that each style is fully self-contained?

I see a funny behaviour with the check widget. Left-clicking, as 
fast as I can, is no problem. Right-clicking fails sometimes. It 
seems, a fast double-click isn't noticed.

Nice job though! :-)

Pekr: code will be shared where it makes sense, and it will be made 
obvious (i.e. no hidden or subtle dependencies).


Geomol: It's a windows specific problem (probably trying to access 
a context menu or something first). I noticed this a while back when 
mapping left / right mouse clicks to zoom in / out ... works fine 
on Linux though.

in all cases REBGUI is a good enhancement yet to VID :)

it includes yet more usefull widgets and less memory usage than VID

but it's a 1 month alive project Ashley and Vincent have done most 
of the work alone so if ppl will give a hand and help ashley concretly 
by apporting code things could advance faster

apporting code to any project is hard I understand this but a first 
step (what I try to do ) is to apport yet existing bunch of code 
that are fitted to REBGUI Ashley takes then the role of merger and 
last adapter. I hope this free some time for him  to focus on work 
of the engine.
