Graham - aren't character of integer field another level of complication? 
Let's have one type of field, with kind of clever masking/validation 
- then, using the SAME rules, let's define your character or integer 
field, please ;-)

*Some* validation can only happen after the event -- unless you enforce 
the order in which fields are completed. And even then it's not always 
possible.

May you need some lightweight masks for simple things. Plus the ability 
to skip off to a tailored validation function for the more awkward 
stuff.

It depends upon how easy this is to implement.

... it was just food for thoughts from my side - maybe most of developers 
don't need such advanced functionality ... so let's think about possible 
ways of how to implement that and then let's present some solutions 
...

I am currently doing field validation by datatypes, but it does have 
it's limitations as Pekr says.

Is a zip code an integer! or string! Is a password field string! 
or integer!  ?

zip code might by an integer, if the space used in that is part of 
your mask - e.g. in CZ we have "739 92", PL uses "73-992" etc.

(not mentioning some countries, which allow chars,not just digits)

Good questions.....A zio code format depends on the country....even 
if you switch masks vy country name, the country name may be entered 
after the zip code.

You'll only handle that correctly with post-form completion validation.

vy == by

load  "739 92"
== [739 92]

imo some simplified parse dialect could work (we have Gab's parse 
rules, so we could be able to define parsing rules dynamically, or 
we implement it other way, dunno), the tricky part could be, if you 
would like to do validation upon each event (key-press), or only 
when your field is losing focus ...

in some ways you have to implement a mini editor for the field.  
prevent scrolling. skip over characters.

Back again regarding the data format for tables, sometimes I want 
to include a database key in the data without displaying it.  So, 
it might the 3rd element in a row where there are only two columns 
displayed.  With a flat data spec, I can not do this.

Also, I don't know if this is intended, but if you manage to click 
on the arrow in a table header, nothing happens.  to sort, you have 
to avoid the arrow.

show-focus highlights all the text in a field. Wonder if better to 
just show the cursor at the end.

Note the following user-configurable blocks under ctx-rebgui/edit:

	tabbed: [area field edit-list password button]

	hilight-on-focus: [field edit-list]

	caret-on-focus: [area field edit-list password]

	action-on-enter: [field edit-list password]


But its probably a good idea to agree on the "correct" default behaviour 
anyway.

show-text ( I think ) should set the slider back to the top when 
used with an area widget.

If you do a show-text area {some rather large text},and then do a 
show-text area with small text, the small text appears at the bottom 
of the area field.  If you then click on the area field, it moves 
to the top.

You have to use the slider to move to the bottom of the large text 
before showing the small text to see this.

Area / scroll / slider reset definitely needs more work.

Thanks for commenting James.

Should a double click also fire the single click action ?

It does by default as a double-click generates two 'down actions 
with the latter having event/double-click = true. This is usually 
a good thing anyway as (in the case of lists with a highlight bar) 
double-clicking a new entry automatically triggers the default single-click 
action (highlight a new row) plus the double-click action we are 
interested in trapping.

Any reason why request-file has lost the /keep refinement ?

Version 1.3.1.3.1 has /keep. Is it in a newer version?

Rebgui redefines 'request-file without the /keep refinement

Oversight I think. ;)

Ahh....

I'm doing some async io, which works with View, but in Rebgui, I 
get the following error when I click on my button

            face/action face
        ]]
    where: 'switch

nope ... something else going on.

I think, that Cyphre will be able to give you an advice on that

it was my fault

Ashley - why request-date was redone? It has strange metrics here 
... too wide (x axis) and it looks like 80ies jurrasic Win3.1 period 
with btns :-) - old look was much nicer with chevron kind of buttons 
... and it was merely the same size X and Y axis wise ...

Had to increase width to account for longer three letter day abbreviations 
(previous version used two letters), but having each cell being a 
square yielded too much white space (especially when the last row 
has no entries in it). "<" and "<<" buttons will eventually be replaced 
with SVG icons when support for that is added.

Thanks for your answers, Ashley. Will SVG support be RebGUI system-wide?

Ashleny, just wondering how complex a GUI you've managed to build 
with the current version.

*Ashley*

Though I guess tour.r is pretty complex

Pekr, yes. The code for svg-toolbar, icon, etc widgets is all there 
... just waiting on SVG renderer project (which in turn is waiting 
on some REBOL/AGG fixes).

Graham, I've messaged you privately. When I get back from the DevCon 
(November 1st) I'll put some screen-shots of some of my commercial 
apps up. Maybe a demo or two as well.

Any idea on why this error occurs?

I'm setting a radio-group using the following code

field/pane/2/feel/engage field/pane/:value 'down none


The radio group appears in a pane, and if I display that pane first, 
then there is no problem.  But if I try it before I display the pane 
containing the radio-group, I get this error.

Because data is none?

>> layout [r: radio]
>> probe r/data
none

this is rebgui ..

I suspect that a value is being initialised only on showing it, when 
it should be initialised with the display function.

Off to Italy, back in 5 weeks.

Anyone working on a toggle widget ?

Can i ask anybody: is anyone working on a witget GRID (or similar 
- for example: text-list with more(multi) columns)?

How is that different from a table widget ?
