To illustrate my point: https://gist.github.com/0bca5a676537008a910c (Top
one works, bottom one causes segmentation Fault). I realise this may be a
seperate question, but it could also be that something is very wrong with
my coding environment!

I've tried both and they work for me (Ubuntu 12.10, ruby 1.9, green
shoes).
I thought it might have something to do with the differences between
both shoes versions but I guess the reason must be somewhere else. Both
work fine in green.


In general, have a look at these:
http://ashbb.github.com/green_shoes/vs.RedShoes.html
http://ashbb.github.com/green_shoes/Red_Shoes_and_Green_Shoes.html

however, there are a few more differences pointed out in the green shoes
manual: http://ashbb.github.com/green_shoes/

I usually use green shoes but I am no expert in either one yet:)

love shoes!

Well thanks for testing them, it very my seems to be a windows error of
sorts, perhaps it's time to port to Java or some such! I small keep
battling the bugs for awhile longer though!

Hi Stuart, J, Seba and folks,

Sorry for my late reply.
As J is already guessing, this may be a Windows issue.
You can shift the focus among the Native objects (i.e. EditBox, EditLine,
ListBox, Button, etc.), but can't remove it. Once Shoes gives the focus on
a Native object (e.g. an edit_box object), `keypress` can't get anything...
:(

So, if you agree to use Green Shoes and to write your app without EditBox,
the following snippet may help you... hopefully.

require 'green_shoes'
Shoes.app do
  list_box items: %w[red green blue yellow] do |lb|
    alert "#{lb.text} is selected!"
  end
  flow width: 300, height: 200 do
    background yellow
    @msg = para
    @msg.cursor = -1
  end
  nostroke
  r = rect 100, 300, 100, 100, fill: red
  r.click{r.style fill: blue}
  keypress do |k|
    case k
      when 'Right'
        r.move r.left + 100, r.top
      when 'Left'
        r.move r.left - 100, r.top
      when 'Up'
        r.move r.left, r.top - 100
      when 'Down'
        r.move r.left, r.top + 100
      when 'BackSpace'
        @msg.text = @msg.text[0...-1]
        flush
      else
        @msg.text += k
        flush
    end
  end
end

Wow, glad to hear that. Thanks for the confirmation. :)

@Stuart

I've also tried both and they worked on my Windows 7.
But I'm using
- ruby 1.9.3p194 (2012-04-20) [i386-mingw32]
- green_shoes (1.1.367)
- gtk2 (1.1.5 x86-mingw32)

So, gtk2 is not the latest version. What version are you using?

ashbb

@ashbb

- ruby 1.9.3p362 (2012-12-25) [i386-mingw32]
- green_shoes (1.1.367)
- gtk2-1.1.9 x86-mingw32

I'll roll back my gtk2 and see what happens... Nothing.

Same error, which I've uploaded, along with the exact code to: [
https://gist.github.com/b95869410c83d6d6a148]

I can possibly lose the list boxes if I make the drawing horizontally
scrollable. I understand I can do that with GTK2 correct?

@Jake

Thanks for checking for me! Always good to narrow down where the bugs are
hiding!

Follow up question, like textboxes, do shapes have to have their
width specified in green shoes? I having trouble placing my rectangle array
the same way my original red shoes does it!

FYI: Green shoes keypresses work on wasd without list_boxes, so thanks for
the help everyone :D

Oh my! Both snippets you posted work well with Red Shoes on my Windows.
We seem to find another difference in platforms... :-P

@Stuart

Sorry, I had kind of confused...
Could you let me know if the following snippet works or not?

require 'green_shoes'
Shoes.app do
  list_box items: %w[red green blue yellow] do |lb|
    alert "#{lb.text} is selected!"
  end
  edit_box
  nostroke
  r = rect 100, 300, 100, 100, fill: red
  r.click{r.style fill: blue}
  keypress do |k|
    case k
      when 'Right'
        r.move r.left + 100, r.top
      when 'Left'
        r.move r.left - 100, r.top
      when 'Up'
        r.move r.left, r.top - 100
      when 'Down'
        r.move r.left, r.top + 100
      else
    end
  end
end

I wrote
- "Once Shoes gives the focus on a Native object (e.g. an edit_box
  object), `keypress` can't get anything... :("

But in Green Shoes, keypress seems to get everything at any time.

About your `Follow up question`.
There may be a few differences to specify shape's width.
Could you show me the code you want to write?

ashbb

@ash

That snippet works fine, so it must be my code. I may rewrite it from
scratch and see if that solves anything.

So essentially what I'm trying to do is this:
http://i.imgur.com/Irb4FEQ.png(Red Shoes program) - Where that
coloured grid can expand in all directions
indefinitely. Horizontal would be nice, but it's currently replaced by the
exceptions list_box at the top, showing different horizontal portions.

In green shoes it appears as: http://i.imgur.com/lcBb4tu.png and I can't
seem to get the grid into the correct place! Nor do list_boxes work without
Seg faults, and I'm at a loss to integrate scrolling from GTK!

The current code for both is: https://gist.github.com/04beb9c20d3a75db70bc

An 'ideal' Java swing mock-up is http://i.imgur.com/W44JXXU.png - but Swing
is so unwieldy to code, and I'd be the only one in the project able to fix
bugs, hence my reluctance to jump the shoes ship!

Ok key presses are working now, using 'Up' 'Down' etc, but even just
directly copying your listbox code into my program and then trying to use
it causes a fault!

Found the list_box Segmentation fault error, had the Red Shoes version of
the image code. Removed it, and it works for the phenotype list box, but
whenever I use the exception one a SECOND time, ie after the map has been
populated once, it crashes. Could be to do with it not being in the correct
place yet, not sure.

Hi Stuart,

Thank you for the details.
I edited your lutrasdebtra/GreenShoesV2.rb a little bit for Green Shoes.
Try it out. ;-)

Hello,

Been AFK last few days - long weekend here in Auckland, New Zealand - code
works perfectly!

Thanks for your assistance, if I finish the project I'll be sure to post it
so you can put it in your samples!

Cheers,

Stuart

@ashbb even without the edit_boxes the buttons still take focus when key
commands are entered!

hi all,

  @Stuart - both snippets also run just fine on my setup...  Ubuntu 12.04,
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux], green_shoes
(1.1.354)    -  so this is probably a platform issue as ashbb suggests.

  @ashbb - good to hear from you - i've been off the radar for a while :/
 thanks for the idea, but under red shoes it doesn't seem to work for me...
 i also tried tying the edit_box focus to a button click, and that doesn't
work under red either:

Shoes.app do
eb = edit_box
button("focus edit_box"){eb.focus}
end

  ...under green shoes, the edit_box has the focus when the window opens -
an interesting difference from red shoes where it does not.  also, this
snippet works for me under green, but not red:

Shoes.app do
eb = edit_box
lb = list_box items: ["a", "b", "c"]
button("focus edit_box"){eb.focus}
end


  - j
