[!RebGUI] A lightweight alternative to VID

:-) .... but it also does not mean, that things like exposing some 
central settings to some objects (as colors etc.) should necessarily 
bloat RebGUI, or does it?

Ah.. I have too many things that rely on the internals of the radio-group 
.. perhaps try another day

Graham, "is there going to be a formal syntax description for the 
rebgui dialect" ... I can certainly get the ball rolling, can you 
point me to a good format we can base it on?
Graham

not really .. can we just use datatypes to describe the syntax?

Something like: http://www.rebol.com/docs/view-system.html#section-2.2

Ashley, that would help.
the problem is this line ... pf: face/parent-face
pf is none
I recall having similar problems with Ashely's radio-group as well.

In the select-item function, need also this : picked: item
as otherwise the picked function fails if you use the select-item 
to set the radio-group
submitted radio-group bugs to trac ... seems a large number of active 
tickets :(
What's the best way to allow a user to define their own forms without 
reimplementing Vid or rebgui parser ?

I just tried rebgui, and I have a few questions ...

is there a reason, that display opens the windows, but does not start 
do-events? This seems a bit strange to me. When testing layouts in 
the console, I mostly end up with inactive windows.
Is it possible to get the window size?
Is it possible to set an own resizer function?
I have tried to create something like a calendar layout:

two TEXTs, and a TEXT-LIST below them, and then 2 rows and 2 columns 
of this. 

The internal resizer was not able to cope with this, either the left 
widgets, or the right widgets were resized. Is it just me, or is 
the resizer not able to cope with this?

show us your code...
RT is promoting Rebgui http://www.rebol.net/article/0280.html

Version 1, left, down resized ...

display "Test 1" [
   tight
   text 40 #w "free" 
   text 10 #w "11"
   text 40 #w "empty" 
   text 10 #w "12"
   return
   text-list 50x50 #hw data ["entry1" "entry2"]
   text-list 50x50 #hw data ["entry3" ]
   return
   text 40 #w "nothing" 
   text 10 #w "21"
   text 40 #w "whatever" 
   text 10 #w "22"
   return
   text-list 50x50 #hw data ["entry1" "entry2"]
   text-list 50x50 #hw data ["entry3" ]
]
do-events
Version 2, upper left resized ...
display "Test 2" [
   tight
   text 40 #w "free" 
   text 10 #wx "11"
   text 40 #wx "empty" 
   text 10 #wx "12"
   return
   text-list 50x50 #hw data ["entry1" "entry2"]
   text-list 50x50 #hwx data ["entry3" ]
   return
   text 40 #wy "nothing" 
   text 10 #wxy "21"
   text 40 #wxy "whatever" 
   text 10 #wxy "22"
   return
   text-list 50x50 #hwy data ["entry1" "entry2"]
   text-list 50x50 #hwxy data ["entry3" ]
]
do-events

the first one you need a #Y for those you want to have a y displacement
what's wrong with the second one?
I've been looking at how to save a form contents and reload the same 
values when opening the form.
all the widgets are anonymous
when I save the form contents, I just go through the pane and grab 
all the values for the widgets I have viz: radio-groups, and edit-lists.
And to restore the form contents, in the do block of the layout, 
I go thru the layout and restore the values.
Only trouble is .. it's not working for me.
How to reference the layout from within a do block ?
I can't use the reference returned by 'display because the display 
hasn't finished yet.

IIRC you have it in 'face in the do-block

Let me try ..

display "Example" compose [
    button "a" [alert "hi"] field "a" return 
    button "b" field "b" return 
    do [
        foreach fac face/pane[
 probe fac/text
]
    ]
]

confidential code?
Graham

[4002x3]
display "Test" [
	group-box "Box1" data [
		field 100 return
		field 100 return 
	]
	do [	
		foreach f face/pane [
			if f/type = 'group-box [
				foreach t f/pane [
					t/text: copy "hello"
				]
			]
		]
	]
] do-events
works fine
not confidential code .. just very long!

i am sometimes good at probing.
