hi, how i can force a field to be disabled ?   i try myfield/options: 
[info]  but it don't work !!!!

You can toggle enabled/disabled with the set-state function.

Example app: display "test" [a: field do [set-state a]] do-events

great thank you very much ;-)

With build 216 I get this:-

>> display "" [f: field do [set-state f]] do-events
** Script Error: set-state expected state argument of type: logic
** Where: init
** Near: set-state f
But better result gives this:-

display "" [button disable] do-events ;- this simple (I can't change 
sending messages on my Mint, sorry for multi replays)

Just found out how to

... it doesn't

work (sorry again)

set-state f false

hi, i would like to change the image of a variable

my-image: image %./nophoto.jpg

i try this but i have a black image !!!!!

my-image/image:  make image! 60x80 load %./Photos/test.jpg show my-image

i wonder if set-values works ?

is missing a set-image ;-)

someone have a solution ?

rebgui 118

iam stupid ;-)    my-image/image: load-image %./Photos/test.jpg show 
my-image

Replace 'load-image with 'load unless you want to cache the image.

thanks Ashley,   do you find a way to correct Build 218 and drop-list, 
menu etc....    ?

Bit of a hiatis while R3 comes closer to fruition, so no.

Hi,

I want to give Rebgui a try for an app i need to do. So, i need a 
tree in there, which should be filled from database request  when 
the app starts. Not via button click.  Can anybody give me a small 
example how to achive this. Searched the docs, but couldn't find 
something like that.  And be kind with me as i am not too familiar 
with Rebgui till now. I downloaded build 218. What i tried so far 
is set-data via button, but that doesn't seem to work.  A sample 
would drastically shorten my way to get this working. Thanks in Advance!!

Tree is not a fully developed widget, so the easiest way of modifying 
it is to dynamically generate the spec. For example:

	blk: copy []
	append blk ["Pets" ["Cat" "Dog"] "Numbers" [1 2 3]]
	display "Test" compose/only [tree data (blk)]

Does this apply to regui 218?? I get an error, that display has no 
compose refinement!

OK , my fault. Should have studied the example more precisely. Now 
it is working perfectly. Thanks for your assistance.

You say that tree is not fully developed. Can tell me, what limitations 
it has?? Is tree able to react  on events, when i click on one of 
the branches of the tree??

Many widgets have accessor functions (e.g. add-row) that allow you 
to dynamically modify them. The tree widget lacks these but is fully 
functional in all other respects.

Are there any plans to update the widget in the near future or do 
you have other priorities?? Can you tell me which of the widgets 
already have these accessors, to have a look at??

Ashley - what is your status re RebGUI and its future? It seems to 
me, that R2 brach is not going to be further developed? And also 
- I noticed you mentioned some flawor of even more simplified RebGUI 
like engine for R3. Is this still a plan, or do you wait for how 
R3 VID emerges?

No immediate plans to update tree widget. For accessor functions, 
search for the word accessor in hhttp://www.dobeash.com/RebGUI/widgets.html

what is your status re RebGUI and its future?

 ... RebGUI does most of what *I* need it to do at present, but I'd 
 really prefer to be using R3 + SDK + Cool looking R3 GUI. I'm experimenting 
 with a minimalist GOB-based R3 GUI, but it's more an intellectual 
 pursuit to see how minamalist (and functional) I can get it ... so 
 don't hold your breath.

I have a menu as the top widget in my window. I think i tried every 
possible combination of the sizing attributes (#LOV, #HW, margin, 
tight and space). The menu sizes to nearly the full width of the 
window but keeps a distance (seems like 4x4)  from the rigth window 
border. Is there any explanation for this space on the right??

See margin, tight and pad ... http://www.dobeash.com/RebGUI/user-guide.html#section-3.4

Thorsten,  take a look at the point of sale application at http://re-bol.com/rebol_crash_course.html#section-5.14

Nick, are the samples using RebGUI strictly intended for v117? I've 
tried a few with 118 and they seem to crash when poking around the 
UI.

Why do you think it's called a "crash-course" ?

I wouldn't use 118 ... it's incomplete

wasn't paying attention, I guess  :-) Is 118 a new start?

There were some major changes made which were never finished.

Cute Graham :)  AdrianS, I've only used that code with RebGUI version 
117.

... which is still the latest official release ( http://www.dobeash.com/download.html
)


118 was the commencement of a makeover but as Graham says broke a 
lot of things. The 118 efforts morphed into an almost total rewrite 
of 'the engine' (everything bar the widgets) and were about 90% complete 
(build 218) when R3 gobs hit the scene (a game changer IMHO).

I found out that the space on the right results from a margin command 
later in the script. I used tight on the top before the menu widget. 
If i didn't reset the margin, menu  fills up to the right. If i want 
to reset the right margin to 4 px later to indent the following widgets 
to the left, it resets the margin for the complete window to 4 px. 
That means for  the menu as well. Now i have a workaound  an use 
a 4 px box to keep the distance from the right border. As Rebgui 
will not be developed any further, it seems that i have to live with 
it. I have chosen build 218 because of the better design, compared 
to the previous ones (My opinion) But thanks for the hints.

What is this build 218? Typo? I thought 118 is the latest.

No typo or not mine. It is a development build from Ashley and Graham, 
not GA.  Ashley mentioned it (90% finished rewrite) in his previous 
post.

scratch that question - I don't know how I had pulled down a version 
118 before

The current edit-list shows the matches where you are typing which 
is a little distracting.  How about the drop list appearing with 
the matches  instead?

What I'd like to emulate is this http://rxterms.nlm.nih.gov:8080/

since the drop list uses a modal popup window I guess it would require 
a lot of modification :(
