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.

Build#100 uploaded with fix to above problem.

The "set focus" problem cannot be fixed given the order of calls 
to 'show within the widget. The check trigger issue can be addressed 
with code similar to that given above for the save button sample.

Yep, fixed.

Is there a way to program a drop/edit-list to drop the list without 
having to click on it?

Ashley;  Congrats on hiiting the RebGUI century mark.  Deserving 
of kudos.   Hip hip hooray!  :)

Thanks.

Graham, how about something like:

	display "test" [
		d: drop-list data [1 2 3]
		button [d/pane/action/on-click d/pane]
	]

that works :)

Ashely, any way to get the caret appear at the click point of an 
area instead of always defaulting to the end of the text??

Hmm, I'm sure it never used to do that ... I think a bug has been 
introduced along the way. Need to fix that one.

it has done this for as long as I can remember

Is there a way to tell a table to sort on a particular column?

Sure.

display "" [

 t: table 60x40 #HW options ["ID" right .3 "Number" left .4 "Char" 
 center .3] data [
		1 "One"		a
		2 "Two"		b
		3 "Three"	c
		4 "Four"	d
		5 "Five"	e
		6 "Six"		f
		7 "Seven"	g
		8 "Eight"	h
		9 "Nine"	i
		10 "Ten"	j
	]
	button "ID" [t/pane/2/feel/engage t/pane/2 'down none]
	button "Number" [t/pane/4/feel/engage t/pane/4 'down none]
]

Not pretty, but it works.

what about refreshing the table data and keeping the existing sort 
in place?

I think if you use t/redraw it always defaults to no sort

Build#101 uploaded with fix to caret problem. All widgets defined 
in behaviors/caret now focus on event/offset and only default to 
tail if focus change was not caused by a mouse click (i.e. tab or 
a manual set-focus).

Can area widgets take a background image?

Most widgets, including area, can:

	b: load %a.png
	display "" [
		field %a.png effect [fit]
		area b effect [aspect]
	]

I should have guessed !

In the following script I would like to be able to click on a row 
of the table to populate the data entry fields, so that I can edit 
the data for the record displayed in that row. How do I do that?

check out t/selected

Thanks, Graham. I'll check.

I'm putting in some background text as an image as a prompt to users, 
but it would be nice to clear the background image as soon as the 
user click types anything like those search fields in browsers

like this   field effect (to-image layout/tight [ backdrop white 
text "enter search term" ] font-color 230.230.230 ) [ aspect ]

I'm sure there's a native rebgui way of doing this rather than using 
'layout !

(to-image layout/tight [ backdrop white text "enter search term" 
 font-color 230.230.230 ] )

and have it restored when we clear the field

How about:


 field %a.png effect [fit] on-focus [face/image: none true] on-unfocus 
 [face/image: load %a.png true]

Looks logical - I'll give it a go.

It's getting a bit awkward now .. I have to set the image at startup, 
restore it on an unfocus event, and then restore it again if I clear 
the field.

I think I need to store the image in the field itself .. perhaps 
as a new type of field widget

How come things I create end up four times the size I specify?
button "Test" 10x10 maroon [print face/size]
prints 40x40 when I click it...

Johan;  RebGUI doesn't use pixels (well it does, but ...)  It uses 
a unit-size that can be set with the request-ui function.

See http://www.dobeash.com/RebGUI/user-guide.html#section-3.3for 
some details.

Sounds reasonable :) Is there any way to circumvent this for items 
that need a specific pixel size, in my case a picture?

And a related question.. Is it possible to resize the window when 
my picture is changed, so that the new picture doesn't get resized 
to the previous one's size?

Well, RebGUI allows for widget design but that can seem complicated 
at first.  Another method is judicious use of the span attributes 
and surrounding widgets with box elements set up like elastic widgets 
that will take/give all the space during a resize.


Or wait till Ashley reads this and responds as he always has the 
best and simplest advice.  :)

Is there a way for 'display to just return the layout without viewing 
?

like display/only ...

Umm...check ctx-rebgui/layout  but the source for display does some 
other nifty things other than just create the face.

Is there a way to set a backdrop to a display?

I tried setting lo/pane/1/image but that sets the image to the first 
widget in the layout
