World: r3wp

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.

If you use DRAW, as Henrik suggest, the result will look prettier.

maybe not, since downscaling in R2 DRAW does not support filtering. 
that's only possible in R3 DRAW.

upscaling will work, however.

That's not what I see. Try:

i1: to-image layout [origin 0 box 300x150 red "An image"]

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

view layout [image i1 image i2 box 300x100 effect [draw [image i1 
0x0 300x0 300x100 0x100]]]

The eye is cheating you here. In fact it's just fuzzy, not antialiased. 
I've investigated this closely.

do http://www.hmkdesign.dk/rebol/thumbtest/thumbtest.r<--- try this 
and you'll see it.

(and that's why R2 DRAW is largely worthless for creating thumbnails. 
R3 is however very good at it. :-))

ok, good info! :-)

Yes, good info! Thank you Geomol & Henrik 8)

Calling all gurus: Now that the R2 mezzanine source is in DevBase, 
we can fix VID2.


Anyone who has developed extensive patches for bugs in VID2, we could 
use your help in fixing them for real. Particularly since any fixes 
might break your patches - we really want to avoid breaking existing 
code when we don't have to. We need input from anyone who understands 
VID2 well enough to know what is wrong with it. We will not be changing 
the basic semantic model of VID2 though - that's what RebGUI and 
VID3 are for.


Anyone who wants to help, join the R2-Beta world if you haven't already.

post to ml too, please ...

I would like to participate but an not sure what to turn to: for 
now I am using 2.7.6 and only have a couple of quirks.  Is there 
a link to dev base?

Are you on the R2-Beta world? That is where the work is happening.
