Yeah, they also have event bubbling .. so a click can propagate outwards 
for other things to deal with

We need the ability to create events
 - so you should try make event!

event bubbling - that's part of R3GUI.

Rebolek - I know make event! is possible, but does it actully work? 
IIRC it was not fully working in early alphas? So you say I am able 
to simulate e.g. a keypress, mouse event, etc.?

is make event! attached to a particular GUI object?

Yes. I haven't got use for it yet, so I tested it only briefly. But 
I was able to create event!, send it to another face and process 
it.

Graham no. It's up to you what are you going to do with that event.

Graham - why should it be? I expect it being just a structure/object, 
you fill in the data, and it gets inserted into the event queue, 
then your objects react accordingly, like if the event would be generated 
by normal action.

So, how you would you simulate a mouse click on a button then?

a button that might be buried by another window on top of it?

I would simply call on-click for that particular button

graham - the gui has many nice features/handlers. There are things 
like do-face, do-style, not sure if cause-action is there (IIRC it 
was part of Gab's GUI)

resize on a window?

do-style window 'on-resize win-size

eventually we'll need the automated test system, so an "event machine 
gun" is needed.

and a way to record macros?

is there a way to enter characters into a field ?  Like the DEL, 
and Backspace ?

macros could be derived from the undo system

Is Pekr's port of the demo available yet?

I am going to work on it a bit today, and tomorrow, then I can release 
what I have ...

I am really nervous about things like removing the easy ability of 
changing the color of something easily, and if it will unnerve me 
in the future, I will fork it ... :-)

I want freaking to change the color of the scroller, the way Carl 
did it easily, via span-colors, easily changing the gradient. Material 
system is useless for me, if I can't do so easy things the esay way 
...

I am looking for the GUI for massess, not for academic stuff ...

Any hints how the material system work? How do I "destylize" panel 
for e.g.? Let's say I want panel functionality, but without the visuals 
(if I enclose everything in panel, there's too many borders and gradients 
around, and I would like to have more relaxed design). Let's say 
I would like to create derived style, called panel-, panel-less, 
pure-panel, whatever. I can see following draw code:

draw: [
			plain: []
			gradient: [
				clip margin-box/top-left margin-box/bottom-right
				pen none
				line-width 0
				grad-pen linear 1x1 0 gob-size/y 90 area-fill
				box (margin-box/top-left + 1) (margin-box/bottom-right - 1) 1
			]
		] 

And following on-make code:

			on-make: [
				make-material face get-facet face 'material
				set-material face 'up
				all [
					get-facet face 'area-fill
					set-facet face 'draw-mode 'gradient
				]
				make-panel face 'panel
			] 

What I am supposed to do, to change the disign?

When this is created properly, the basic panel should have no visible 
frame.

Then other styles would derive from it and add the necessary frame.

yes, but what's the usage case?

e.g. following function (trying to study material system):

set-material: funct [

 "Chooses the gradient from a material object to use with a face mode"
	face [object!]
	mode [word! none!]
][
	all [
		mat: get-facet face 'materials
		set-facet face 'area-fill any [
			all [mode select mat mode]
			select mat 'up ; default mode is 'up, for none inputs

   select mat first words-of mat ; if 'up does not exist, use first 
   word
		]
	]
]


E.g. for panel, there is no 'materials facet, just 'material one, 
as can be seen in on-make actor ....

hmm, progressing slowly, but at least something:


>> view [p: hpanel [button do [print mold get-facet p 'materials]]]
make object! [

    up: [0.0.0.200 0.0 0.0.0.255 0.5 255.255.255.255 0.5 255.255.255.220 
    1.0]

    down: [0.0.0.200 0.0 0.0.0.255 0.5 255.255.255.255 0.5 255.255.255.220 
    1.0]

    over: [0.0.0.200 0.0 0.0.0.255 0.5 255.255.255.255 0.5 255.255.255.220 
    1.0]
]

== make gob! [offset: 566x379 size: 148x42 alpha: 0 text: "REBOL: 
untitled"]


>> view [p: hpanel [button do [print mold get-facet p 'material]]]
container-groove

== make gob! [offset: 566x379 size: 148x42 alpha: 0 text: "REBOL: 
untitled"]

Why does following does not work? I try to set the panel to the 'plain 
mode, but calling 'show crashes the code:


>> view [p: hpanel 200x200 [button do [set-facet p 'draw-mode 'plain 
show p]]]


So - how do I refresh/redraw the panel? Should I somehow call the 
'on-update actor?

does the panel style have a draw-mode 'plain?

yes, an empty block :-)

What is the correct way to call an actor? do-style face 'on-update?

shouldn't it have an argument?

how can I recognise, what arguments particular actors should obtain, 
if not in the comments? :-)

I believe that is a problem that is yet to be solved.

How can I properly attach scroller to progress bar? Following code 
shows scroller at 100% value. Scroller accepts some initial size 
parameter, but not sure how to utilise it either ....

view [prog: progress sbar: scroller attach 'prog]

Why text utilising rich-text does not work either?

'drawing style has not effect too:  view [drawing [pen black circle 
50x50 30]]

I really wonder, if R3 GUI sees ANY regular development? ;-) Half 
the styles don't work or don't work as expected :-) Recent R3 GUI 
status is, that it is not usable for more than simple dialog box 
:-) I hope that we can see some quick fixes? :-)

There are still many things to solve, so there are bound to be many 
regressions until we reach a point where no more features are needed 
for now.

I know Henrik - but I thought that there is someone actually working 
on styles? Possible Bolek? I was about to "port" rewrite demo, not 
to redo styles (which is beyond my capabilities :-) Most of things 
I mention here are obvious by very simple examples, so I wonder if 
someone tested them, or what is the "action plan" towards the GUI 
progress?

Bolek is working full time on styles, particularly tables.

The plan is to do styles on priority with needs with the SCRUM tool, 
that's why tables are being worked on right now. Also continual design 
reviews are necessary to make sure we won't run into design dead-ends. 
That's why there may be regressions.

tables - nice, and good to know ...

Petr, as said hunndred times... we are first drilling deep to get 
the concepts right. Than we are boing broad by priority. This means: 
Focus on few (2-3) styles

Everything that is eye-candy has no priority at the moment. This 
includes: Material system, rich-text, DRAW effects etc.

I a sense, this is very disappointing, as we have no more the possibility 
to use the Carl's gui, and the RMA 's version seems far from being 
usable !

It's available, take it and help us to port more styles. Again, this 
was said several times. If you don't want to, than you have to wait.

We are not going to change our strategy, in this we are very stable 
and predictable.
