Would a statically stacked tab-panel suffice? I could knock up a 
tab-panel2 widget that accepted two blocks of label / action pairs.

Yes.  Though I guess some people might want 3 levels ...

HTML: Doing static layouts would be OK in the first step.


And, this declarative stuff like hooking input-streams, to output-devices 
is IMO a good aproach. A lot of technologies from the mid 80s / erlay 
90s are possible these days. IMO there exist a lot of forgotten things 
that are pretty cool.

Graham;  I'm being facetious; but who, other than you, writes apps 
that need that many tabs.  You're adding too many features.  :)  
More seriously.  I've hacked an overlay widget by pulling the tab 
pane out of  Ashley's tab-panel (build 95)  that uses the same layout 
model and his select-tab action.  Put up a couple of arrows and you 
can stack as many tabs in an overlay space as you'd like (they would 
not scroll one at a time; it'd function as banks of tabs; one tab-panel 
per overlay "tab" but it'll save a fair amount of screen real estate). 
 I could post the code somewhere if you'd like.

Multiple lines of tabs are sometimes solved with just one line, and 
"scrollable" tab panel style - you get arrows on the left and on 
the right side, so you can have as many tabs as you wish. Of course 
pushing users to scroll is not very much intuitive, but it solves 
the case ...

post away :)

but I only have 4 tabs at present . it's just that I don't have the 
horizontal space

So, I need to stack the tabs vertically to employ the vertical space 
available.

I don't like the scrollable tab style because you can't see all of 
the tabs available in one glance

Graham - Cyphre's styles pack contains tabs with arrows, so that 
you can have more than is visible space. Horizontal only though ... 
You could contract Cyphre to do it for RebGUI ....

Code at http://peoplecards.ca/rebol/ld2-rebgui.rUse it just like 
a tab-panel.  I use the text that would go  on a tab for a comment. 
 Use show widget/select-tab n  to switch between overlays.  The code 
 conditionally loads rebgui and the widget; so if you are modifiying 
anything, you'll have to unset ctx-rebgui for each test load.

Sorry, don't call show with select-tab

I'll give it a go .. thanks.

Ashley I'm still seeing the dbl click on an edit-list bug

Brian, the advantage for a true tab panel style is that the currently 
selected panel keeps the button highlighted.

So, this is more of a button panel style :)

I use it to emulate the overlays in the Desktop Library, but I thought 
you might use it like 

overlay data [ "1" [tab-panel  data [ ]] "2" [tab-panel data [ ]] 
 with a couple of arrows, or buttons :) or menu options to determine 
what bank of tabs are shown.  As with many things, I may not be getting 
what you are really looking for, but I've grown fond of having overlays 
in RebGUI.

Ahhh... never thought of that!

Build#97 uploaded with a 'no-tabs option for tab-panel. Works exactly 
as per Brian's overlay widget as described above.

re: dbl-click problem. I can't reproduce this one. I assume this 
occurs on Windows? What is the dbl-click speed set to? (Control Panel|Mouse 
Properties|Buttons) Is it a mouse or pen (i.e. TabletPC) that generates 
the dbl-click in question?

Re: build 97...Very nice.  I get to dump a hack.  Thanks Ashley.

Yes, windows ... and a mouse.  Speed is set to just to the right 
of middle.

Is there something I can do to trap the error at the widget level 
so it doesn't propagate upwards?

and yes, it's not easily reproducible

I think adding the dbl-action facet to the choose function in ctx-widgets.r 
will 'fix' the problem, as in:

	choose: make function! [
		...
	][
		...
		popup: make face-iterator [
			...
			alt-action:	none
			dbl-action:	none
		]
		...
	]

ok, I'll give that a go

rebgui-widgets.r ?

Yes

thanks

How does one reset a radio-group to it's unselected state?  I tried 
rg/init, and rg/select 0 ( which crashes )

Graham, I haven't ventured into the world of RebGUI other than the 
demos, but in View the data attribute of the radio button is none 
until selected, true when selected, then false when the selection 
is changed.

ie.  Radio5/data: none

I hope RebGUI works the same way.

No, the value of face/picked contains the current selection and is 
set by clicking a radio button or using the select-item function 
which simulates a click. By default it is not possible to simulate 
a null click.

Build#99 uploaded with fix to above. You can now do:

	rg/select-item 0

or:

	rg/select-item none

thanks

display "" [ radio-group data [ "one" "two" ] [set-focus fld ] fld: 
field ] do-events

shows the focus and then loses it

display "" [ ck: check data none [ print "checked" ] button "Change" 
[ set-data ck true ]] do-events

doesn't trigger the action on the check

Do we need a 'set-action function that triggers an action associated 
with a widget?

That's not a trivial thing to do with the current design ... and 
then add the complexity of action types (single, double or alt-clicks; 
combined with various on-* triggers ... it gets messy very quickly).

so, how to trigger the action?

It should just work, I'll take a look at it later today.

table/set-row does a trigger on the action

so, there is some inconsistency

/select-row ?

The action in that case is a by-product of the primary purpose ... 
select a row. select-item (radio-group) does tha same. I can't recall 
whether there's a select-state for check though.

I guess I should not put complicated code inside the action block 
... and just factor it all out.

Depends, you can call action functions directly, as in:

	s: button "Save" [...]
	button "Do A then save" [... s/action/on-click s]
	button "Do B then save" [... s/action/on-click s]

rebol []

do %rebgui.r

pu: does [ display/parent "" [

 table 20x20 options [ multi "item" left .9 ] data [ "a" "b" "c" ] 
 return
	button "close" [ unview/only face/parent-face ] 
]]

display "test" [
	text "Try multi selecting with control" return
	button "test" [ pu ]
]

do-events

multi-select fails the second time round.
