World: r3wp

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

make object! [
    code: 312
    type: 'script
    id: 'cannot-use
    arg1: 'path

            if old [

                show pf/pane/:old
            ]
            pf/data: face/data

            insert tail face/effect/draw [pen leaf fill-pen leaf circle 6x10 
            3]
            show 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 ?

table's functionality is simply insufficient for real database related 
work ... e.g. ability to have data block, and to configure which 
columns to display and which not to ...

So table widget doesn't have a cursor to mark selected row..

.. and function "picked" like text-list..

face/picked/1 is the first selected row

but widget text-list in rebGUI doesn't have multi-columns..

widget table has multi-columns but i can not select any row..  is 
it true?

(sorry i am beginner in english..)

(multi-columns =  i need more then 1 column )

the options word "multi" allows you to select more than one row at 
a time.

maybe he meant simply to have hilighted row, plus ability to navigate 
by keyboard?

yes

i need any widget that can do:  1) hilighted selected row 2) row 
with more than 1 column

widget table : 1) i can have more 1 column - so it is good for me 
   -- but 2) i can not click on row and hilight  it

was it discussed here before? Why recent Rebgui version takes 15MB? 
Playing a bit with demo and it is now 19,5MB after few minutes of 
usage ...

Sorry - i have downloaded v.3.7 now  and i found in widget table 
all what i need ....thank you for your patience :-)

Wait and watch the memory usage ... it tends to drop with GC.

but 15 - 19MB? Wasn't it some 5MB with older versions? What changed 
that memory consumption rised so significantly?

Graham - you going to DevCon?

I think you'll find that the spelll checking dictionary contributes 
to the memory rise.

I'm only attending virtually :)

I made some improvements in the list-view widget for rebgui  ^^ Now 
dynamc widget changes impact on data to be drawn (so when you change 
the state of a checkbox this impacts on the stored data) I make a 
generic callback funtion to allow ppl to save list data into a file 
 on changes. I make some estetical changes too 
I hope you will apreciate it  ^^

this new widget can be found in the web page  
http://www.rebolfrance.info/articles/regui-cooking-widgs

0.52 version of list-view widget is shapped to ork with Rebgui 0.36

it's been a while since i don't get internet connection so I hope 
it works fine with rebgui  0.37

list-view 0.52 works fine with rebgui 0.37

shadwolf, do you know how to remove a tab dynamically from a tabbed-panel, 
and also how to add tabs dynamically?

hum ... tab ?

you mean column or ro ?

row  adding row is mutch more easyer than handleling column ... To 
skip column we have several way to do this ...  one or just estetical 
and doesn't impact upon internal datas and other are about impacting 
uppon internal datas structure then provoc a redraw
