Try setting a field/text field/data to a default text and enter a 
longer text. Should bring the error as well.

Idea: I'm using a lot of data-entry forms in my apps. So getting 
a data-record from the form and putting a data-record into the form 
is a common task. It would be great to have a function SAVE-FORM 
and LOAD-FORM, that collects/restores all necessary widget values.


We could specify a SAVE flag via the options facet for each widget? 
If the SAVE flag is set the widget is collected/restored.

I have used this approach in my own data-form dialect and it's a 
real time-saver.

The format could be: my-record [name/text "Robert" name/data 5]

So it makes sense to be able to specify either the SAVE option in 
which case the default "value" of the widget is collected/restored 
or to specify an other block: SAVE [text data user-data]

in FoxPro, those methods were called Scatter and Gather ...

That is imo what get-face, set-face accessors were supposed to be 
initially imo ....

Yes, on a per widget base. I'm talking about a complete data-form 
with several widgets.

robert: see my devcon registration script. it fixes a few bugs on 
get-face and set-face for panels, and uses the panel accessor for 
the window too. then it just uses get-face and set-face like your 
save-form and load-form.

(i've always been using something like this in my projects.)

100th RebGUI issue logged: http://www.dobeash.com/it/rebgui/issues.html

Gab, you have a link to your script?

; default one is very stupid
my-access: make ctx-access/panel [
    set-face*: func [face value /local val][
        if all [block? face/pane block? value][
            either set-word? value/1 [
                foreach [word val] value [
                    set-find-var face/pane to word! word val
                ]
            ] [
                foreach f face/pane [

                    if any [find f/flags 'input find f/flags 'panel] [
                        if not empty? value [
                            set-face f value/1
                            value: next value
                        ]
                    ]
                ]
            ]
        ]
    ]
]

How about adding: get-text, get-data? I'm always using those non-existing 
words ;-))

margin: Setting the margin in a bigger layout somewhere in the middle 
"margin 4x4" reset the layout cursor so that the next widget is displayed 
at the "top". Seems that changing MARGIN and SPACING inside a layout 
several times has some problems.

group-box: Today an other idea striked me for group-box. How about 
a way to collapse the group-box like a sub-tree in a tree control? 
With this a GUI could be make very dense and only those parts expanded 
that are currently worked on.

This approach is good for top-down approaches in applications.

Robert: I'm using hypernotes for this. There's tree-list on left 
and you can define whatever layout you want with VID tag. I also 
patched hypernotes with SCRIPT tag so I can write code in hypernotes 
and script is generated automatically.

Robert - something like following? - http://www.xidys.com/winbox.jpg
... it is taken from Winbox app, which we use with our Mikrotik routers 
... dunno what they use as their toolkit,maybe Qt?

margin/spacing: added to the list.


The drop-down widget panel is actually a standard interface element 
on Mac (forget the name of it) which looks surprisingly similar to 
the JPG Pekr posted. A worthwhile addition I think, although hard 
to implement (as it changes the offset of every widget below it and 
forces a window resize).

Petr, yep something like this.

Ashley, shouldn't the span stuff help here? I mean it's somehow like 
a spliter put between the box and the next widget line.

Rebolek, is/could the tree-list be made RebGUI compliant? That would 
be really great!! Especially the idea with the VID tag and the SCRIP 
stuff.

Robert: I don't know, I'm not author of HyperNotes, Martin Johannesson 
is. However, he wrote to me, that current version of his list is 
little bit tricky and he's working on new version. So maybe the new 
version may be rewritten for RebGUI. If you like to have a look at 
my patched version of HyperNotes, just let me know.

The problem I see with the general get-face/set-face approach on 
panels is that values are ordered and unnamed. This makes maintenance 
a problem because, depending on how you deal with that data, you 
have to change things, be aware of the order of fields, etc. It can 
be a nightmare IME. Of course, I want a solution that minimizes my 
code, but I'm even more concerned about keeping it correct.

Gregg, I totally agree. And it's one of those things that drive me 
nuts in VID / View. Sorting faces for z-ordering etc. is really no 
fun. And I have no way to get a reference that's stable.

My standard approach is to write collect and display routines, which 
isn't so bad if we have a form framework that can do it intelligently, 
or generate the code for us.

;-) Issued the request to add this to rebgui.

The nice thing is, that if you create a set of faces that need to 
be collected/restored you don't have to use a zillion of face words. 
You specify them via flags.

Gregg: my code above fixes just that, uses name: value instead of 
just block of value.

The approach I'm looking at will flag widgets (via the options block?) 
with both a reference word and an [optional]  datatype specification. 
You will than have functions like:


 put-values my-display [f1: "Some text" f2: 3-Jan-2005 f5: $20.50]

 put-values/all my-display ["Some text" 3-Jan-2005 3x4 "Fourth field" 
 $20.50]
	get-values my-display [f5 f2]
	get-values/all my-display []


so you can put and get values either by reference, or just do the 
whole lot directly with a /all refinement. The optional datatype 
specification will force a conversion on the returned value. get-values 
will stop at the first failed datatype conversion, instead returning 
the widget reference word.


Still in the planning stage, so other / further suggestions welcome.

The interface should be compatible with SQLite, so that no block 
transformation is required. Getting data from SQLite directly to 
the GUI and back.

options block: Yes, good approach.

I expect /ALL only to use ALL widgets that have been flaged.

data-conversion: It would be nice if I can register a call-back function 
that is used.

Just had an unusual enhancement request from a customer of mine. 
As they fill in fields and areas on a form, they want the ability 
to press Ctrl+B to bold the contents of an entire field / area so 
as they can visually note and review what is important prior to clicking 
"Save" and moving to the next form. It would be fairly easy to add 
this to RebGUI (a Ctrl-B bold toggle), but would anyone else find 
this useful?

quite non typical ... I wonder ppl don't miss underlined accelerator 
keys, ctrl + tab to toggle between the tabs and clicking away from 
list-down to close :-)

Because those issues are important to IT folks and totally irrelevant 
to most real world users? ;) Most users don't even know they *can* 
drive a GUI via the keyboard, and if they click on a drop-list they 
*will* pick an item, even it's a blank "no selection" choice (I always 
have the first item of my pick lists as an empty string so users 
can easily click their way out instead of having to press ESC).


  As an aside, what most of my customers were complaining about, until 
  recently fixed, was the fact that drop-lists didn't scale to fit 
  the most items possible ... something no-one here even noticed! ;)

Need request-file/keep .. have to comment out rebgui's request-file 
because it lacks this.  Thanks.

Issue#47 ... raised by ... Graham. ;)

Ashley - that is simply rudiculous. I have 300+ users at my sight. 
Those type data into system. You really depreciate the fact how ppl 
use computer - the mouse is waste of time, totally ...

well, drop list is not good example of how to use gui via keyboard, 
I do agree :-) our users are not typical users maybe, as they come 
from terminal SAP R2historically, where there was no mouse :-)

my complaint to drop-list is, that it is kind of menu ... and in 
rebol it is driven via show-popup? And that is broken .... I am used 
to close menu by clicking somewhere else .... it happens occassionally, 
when I unintentionally press right mouse button etc., and I really 
don't want any option to be selected ..... so I just move mouse out 
of the menu, and do a left mouse press ... not so with rebol ....

ctrl + tab not even being trapped by rebol view engine is total fiasco 
and I was slammed for that one pretty hard ...

If the mouse is a waste of time for your users, then they don't need 
a GUI. Just deliver data entry functionality via a console type application. 
My users [medical] make extensive use of TabletPCs so no mouse / 
pen is a bit of a deal-breaker for me. ;)

the mouse is waste of time, totally

 ... so you don't use a mouse for file management (File Explorer) 
 or browsing? And of course you don't need one for Paint type operations? 
 Not everyone who uses a computer is doing pure keyed data entry. 
 Different strokes for different folks.


Anyway, I'm gradually adding keyboard support to RebGUI as time and 
REBOL fixes permit; but it's not high on my list of priorities.

File management? Ah no, you Windows users :-) I would really like 
to see a video, how one can work effectively using such sh*t like 
windows explorer :-) No, I do use Total commander, totally without 
single mouse press ....

and don't try to suggest type of application for my users :-) With 
our past system (now they use SAP R3 and they do complain), they 
used GUI Visual Objects based app - no keyboard, maybe unless they 
wanted something from menu - all forms plus grid were keyboard driven 
- they complained, if some form contained something requiring them 
to touch mouse ....

I am not saying anything - if it works for you, well then. But - 
it does not work for me. I point to the issue of weak keyboard support 
for years. And I know MANY ppl who comlain for rebol not being OS 
friendly. Just go into OS-X group and look what Geomol says about 
proper OS support. I think that ppl are forgiving to a bit different 
look, but not to non-os-compliant behavior ...

and as for browsing - yes, I very often use keyboard - to open new 
tabs (ctrl t), typing search phrase, pressing arrow down (=pointing 
it to google) .... or simply using "find as you type", enter, backspace 
for navigation :-) But that is available in Mozilla/FF

We have the Rebgui sources .. we can add support as needed if Ashley 
is too busy, or we can wait for his schedule.

If rebol doesn't support it ... better to hassle Carl instead.
