Uploaded fix to SVN.

Working now :)

I've got a widget named 'outcome defined as 


outcome: make text [
	size: 0x5
]

now this displays incorrectly 


 display "" [ label "HAQ" outcome "HAQ" return text "Test" ] do-events

there is a large vertical gap ( twice normal ? ) between the two 
visible widgets

Ashley, would you provide a working example of using the function 
keys ?  I'm having difficulty getting it working.

I haven't found the on-fkey handler yet, but I am hoping that function 
keys are not defined at the face level.  I use function keys at the 
application level ... and modify their behaviour depending on which 
tab has focus.

do %rebgui.r
ctx-rebgui/on-fkey/f3: make function! [face] [print "Hi"]
...
display ...
...
do-events

The handlers are global, the face argument is the face of the display 
which was active when the key was pressed (see %display.r for the 
processing logic).

I tried this with no luck.

What REBOL version?

>> rebol/version
== 1.3.2.3.1

>> do %rebgui.r
Script: "Untitled" (none)

>> ctx-rebgui/on-fkey/f3: make function! [face] [print "Hi"] display 
"" [ text "hello" ] do-events

nothing happens when I have focus on the window and press f3

Works here, and I'm running the same View version.

ctx-rebgui/build?

hand built :(

A merge of my changes with your latest

checking out a new version now

BTW, would it be okay to add caret support to spinner so that we 
can change a single character?

At present we have to highlight, erase and then type over

Function keys working now :)

Must have screwed up the merge I did

You mean add the 'caret attribute to spinner?

if that is what it takes

OK. In your outcome example change the size to 1x5 and add color: 
red to see what is happening.

text (derived from label) is trying to protect you from:


 text 10 "A really long bit of text that should wrap even though I 
 didn't specify 10x-1"


but the problem is that if you specify 10x5 then it should honor 
that regardless of whether the text fits or not. The solution, I 
think, is to change the default size from -1x5 to -1x-1 but ensure 
that size/y is always a min of sizes/line.

I get a red line, which is deeper than specified

I want to hide the widget so, I really want to set it to 0x0

what about:

	text "blah" false

Hmm.  That works

Can I put that in the widget definition?

show?: false

I'm using these hidden widgets to controll the low, high range of 
acceptable values in a widget, and to provide them with database 
field names

ie.form validation and not field validation

Seems an obscure way of doing it ...

It allows a user to define a template like this:


label "Tender joint count? (0-28)" outcome "tender28" ifield  low-range 
"0" hi-range "28" return

so, outcome refers to the database field, and the user has integer 
field for the data, with a low range of  0, and a high range of 28

I guess I could use a custom widget and use options instead

or a spinner?

takes too many clicks

you have to highlight a spinner and type over it

extra work

then add spinner to hilight-on-focus and they can just type overtype 
the value directly.

I think I created this dialect pre-spinner days :)

Does a spinner allow blank field to start off with ?  Trying to avoid 
users accepting default values

Not at the moment. Should it? And if so, should it let them leave 
the widget without entering a value?

Well, I don't want to present a template with prefilled values

because then the user doesn't know which ones they filled in or not
