[!RebGUI] A lightweight alternative to VID

Robert
3-Apr-2006

If you have a form with several fields I want to have something like:
	store data-form
and get back a block like this:
	[name text  "Graham" rebol value true ...]

So for all widgets where the SAVE flag is set, the name of the widgit 
word, the word and value is returned. With this it's possible to 
handle records very comfortable.

blk: get-form my-display


I've got as far as thinking about how it could / should be implemented 
(there are some interesting issues with grouping widgets like group-box, 
table, text-list, etc); but my focus at the moment is to complete 
the SVN setup / structure / documentation / usage instructions so 
as collaborative development can begin (and I am no longer the bottle-neck 
in changes being implemented). Unfortunately, I'm two weeks into 
an intensive four week certification course (non-IT related) so REBOL 
things are on the back burner for a while (although I'm popping in 
here to answer the odd question here and there where I can).

I'm not sure that this is relevant, but I did some basic screen validation 
for vid, and documented here

Is there a "fit" for images as in Vid?
umm... the other way round... display an image in it's native size.
unscaled.

 ... change in what way? Look? Feel? Where the arrows are located? 
 Arrows or chevrons? Colour?

I think Julia wants to do skinning, changing the look of the slider. 
Well, I programmed the slider/scroller, and I can say that it is 
not easy to reskin. You will have to get your hands dirty :)  When 
rebgui first came out, it was intended to be very lightweight, so 
I think Ashley only started to want to add fancier abilities like 
skinning later. When I wrote slider/scroller, I was trying to be 
as minimalist as possible, so it's quite "hard-wired" with respect 
to how it draws itself.
Maybe Julia means how to change the colours ? Well, as I remember, 
I just used button colours.
Ashley, how's the splitting of widgets into separate files going 
? What method are you using to integrate them into the final context 
?
Here is a very simple patch to slider, which makes a nice half-second 
pause at the beginning of a scroll:
				if find [down time] act [
					if act = 'down [face/rate: 2]
					if act = 'time [face/rate: 16]
The above two lines are of course highly amenable to be optimized 
into one. (This way is just more similar to the original code.)
(Just search for the first line "	if find [down time] act ["  to 
find the correct position for the patch...)

Thanks.


 "how's the splitting of widgets into separate files going?" Done, 
 it's all in SVN now: http://trac.geekisp.com/rebgui/browser


Anyone who wants dev access (both source and Wiki write access) just 
drop me a private message and I'll get you a username (same as REBOL3 
username) and password. A lot remains to be done before I open it 
up to full collaborative access, but having a few folks on it means 
we can test the infrastructure / process (in addition to getting 
some changes into RebGUI faster).

Changes like the above are good candidates to start with. ;)

Hi Ashley, I'd really like to be part of the trac RebGUI initiative, 
so, may I ask you to set up an account for me?

I'm currently working on compatible improvements for the tab handling 
to allow tabbing in and out of widgets grouped in e.g. group-boxes, 
which I'd like to see being part of the official distro.

Done and done. SVN client software is available at:

 Mac: http://www.lachoseinteractive.net/en/community/subversion/svnx/features/
	Linux: http://esvn.umputun.com/

What's the way to change the font size and unit sizes?  I see you 
have this in the demo but it's not clear to me how this is used.
ChristianE

Graham, you simply SET-SIZES MY-UNIT-SIZE and SET-FONTS/SIZE MY-FONT-SIZE, 
RebGUI does all the rest. If you then unview and redisplay you'll 
see the changes.
Graham

Ok, I got it now.
ctx-rebgui/widgets/set-sizes unit-size font-size
Someone was trying out my program on an UMPC (Origami) so I needed 
to resize down to that size.
Ashley

Note that 'set-sizes and 'set-fonts are global.
At least in 0.4.1 that is.
Graham

[3298]
ahh.. I just looked at tour.r and you set them within the context.

I have the following problem: I need to provide a drop-list with 
two columns. And one of the columns has long texts in it, so that 
you can't read it if the drop-list isn't made extremly wide. Has 
anybody an idea how to best create the GUI for such a selection?
Maybe something like a tooltip would help...
Volker

or make it clickable and open a text-window?
Graham

Anyway to filter on a table ?
So, only display rows that match a certain criterion?
Ashley

Can you change the size of text within a table?
Ashley
10-Apr-2006
[3307]
Not individually as it uses default-font.
Graham
10-Apr-2006
[3308]
how about all the text in a table ?
Ashley
10-Apr-2006
[3309]
By individually I meant the table in isolation to other widgets (i.e. 
using font [size: nn] instead of set-sizes)
Graham
10-Apr-2006
[3310x2]
Ok.  I've give that a go.
this doesn't work 
mytable: table 25x68 font [size: 5 ] #YH options ...
Ashley

Not individually as it uses default-font. ;)
Graham

[3313]
So, can I set the font size in a particular table isolated from other 
widgets?
Ashley
10-Apr-2006
[3314]
No, as it uses default-font.
Graham

shame.

It's rare to come across a GUI (WinXP, Mac) where widgets have arbitrary 
sizes. The intended use of the font attribute is to change things 
other than size (alignment, style, color mostly) ... but even then 
I like to remind myself that in UI design consistency is king.

True, but ussually fonts do change (even inside tables).


I have always felt teh whole you UI should be sizable.  I really 
liked the NeXT.

actually there are two things: 1) ability to scale 2) ability to 
resize
