How about a great tutorial on how to build the preferences window. 
 Then you kill two birds with one stone ;-)

Henrik, your comments on Xcode are spot on, for the easy first step 
you are rewarded by a sudden learning curve to understand why things 
need to be wired up in a certain way.

.

I'm using a single "area" right now to display a list of notes but 
would I like to do something like what we see here in Altme; that 
is, a scrollable list of rows that have differing heights. Any thoughts 
about how I can accomplish this feat? I tried list with supply but 
all I get is a bunch of areas the same height. I think that you cannot 
have such a thing with list/supply so there must be another trick.

Look at DideC's altme viewer, or, look at the source to my chat client.

Basically you have to construct the whole row as 3 separate faces 
and keep appending them to a much larger face.

James, it is quite difficult to make an iterated list of AREAs using 
LIST, retaining all the correct behaviour as expected for an AREA. 
I remember trying pretty mightily to achieve this, but, in the end, 
I have no example to show. If you were going to try, you would program 
the pane function directly yourself, rather than letting LIST use 
its default pane functions.

So I recommend the approach, as Graham above, of generating real 
faces (at least for the visible part of your list).

I can help you with this, as I've done it a number of times, the 
most recently in my editor replacement (see Editors group).

Anton - your editor work is awesome. I would like to ask, if you 
looked into VID3 styles already, or if you consider becoming VID3 
style's author? I can bet you would be one of the most prominent 
ones :-)

Well, thanks Pekr. I'm quite proud of the editor (which is why I 
keep mentioning it.)

I wouldn't mind seeing an advanced editor built on top of the area 
style for R3

VID3... I've been finding it hard to be inspired in this area.

need the style dialect to be finished first, so we can build all 
the basic styles

Thanks to all of you for your input. That definitely puts me in the 
right direction (and keeps me from wasting any more time with "list".) 
 This morning I took a look at Carl's #29 cookbook and at least there's 
a fast way to get closer to what I'd like. I really appreciate your 
support.

Is there a way to catch the "X" (close) button on a window. I'd like 
to offer a "Save File"

yes, use insert-event-func for that and detect on event/close.

main-window-title: "my little app"

view/new/title center-face main main-window-title
insert-event-func func [face event] [
  switch/default event/type [
    close [

      either event/face/text = main-window-title [ ; only reacts when main 
      window is closed
        quit
      ][
        event
      ]
    ]
  ][

    event
  ]
]

the switch might be a little elaborate. I use it in case I need to 
detect on more things.

Thanks Henrik!

Hello, I search to implement drag'ndrop between 2 windows. How to 
proceed ?

it's not possible in R2 VID

ok, thanks

Is it possible by using View directly ?

I'm not sure you can. Anton may know better than me.

Rebol2  Console can be drag destination:  http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=sys-port-drag-accept.r

Rebol3 can be drag destination on view (drag.r example in rebol3 
alpha) :  http://www.rebol.net/builds/rebol3/alpha/rebol29904031.zip
and  http://www.rebol.net/r3blogs/0098.html

About drag source look  at  http://www.rebol.net/cgi-bin/r3blog.r?view=0098#comments

thanks, unfortunately R2 example need view/pro

2.7.6 test versions are available and have library freed.

cool

how can I find this new version ?

Were testing the final beta now and you should have it very soon.

Graham, what does that mean: "Library freed"? Can you use dll's?

use

afaik ... I've got command so haven't tried it

Hello ! Is use the halt function to stop  to freeze my graphical 
app and open Rebol console .How can I close the console to return 
to my app ("quit" close the app too) ?

you can't close the console again, but you can continue the program 
by typing "do-events". that'll make VID start catching events in 
your program again.

Do you know if the possibility of closing the Console when restarting 
the Vid app will be possible in R3?

since the R3 console will be VID3 based, possibly.

but nothing is built yet

How to reset button state before unview?

l1: layout [btn "win1" [unview/only l1 view l2]] l2: layout [btn 
"win2" [unview/only l2 view l1]] view l1

once I click the win2 button the button from the first layout is 
still in the down state

l1: layout [btn "win1" [face/state: false unview/only l1 view l2]] 
l2: layout [btn "win2" [face/state: false unview/only l2 view l1]] 
view l1

how do I convert an %image.jpg to to a height of 100 and a cropped 
width of 200 ?

I think you need to use draw for that.

Should the height also be cropped?

no

say I have 1200x 5000 adn I want to resize proportionally to a height 
of 100 and crop widht to 200

If your height is 5000 and you resize to a height of 100, your width 
will be less than 100, if it initially were 1200!?

So you just wanna resize height, and not width in the first go?

If i1 is your original image, you can do:


i2: copy/part to-image layout [origin 0 image i1 as-pair i1/size/1 
100] 200x100

This will resize height to 100 and crop width to 200.
