Hey, don't beat yourself up, I knew your code was pretty alpha level. You
made it clear that it isn't done yet. And I *DID* figure it out. I am just
glad you wrote something that solves my problem and works well. Thanks!

That will be great, although, at this point its really Observable that I am
most working with at the moment. Once I get the current stuff working I may
use Foxtails more.

BTW any idea when you will release it?

Sounds great

If I could figure out what the questions are I'll ask them ;^)

As for documentation, I have some suggestions. The part I had the most
trouble with (still do for that matter) is figuring out how to work
observable things in other objects like windows. For example, if a value in
that window over there changes how do I find out about it and react to it
over here in this window. Specfically, how do I write a when_var for a
different object. None of the examples seemed to cover this case. To work it
out I wrote a little test program that I will include below. Some better
documentation in this area would help a lot.

===================== begin include ============================
#!/usr/bin/env ruby

require 'foxtails'

include Fox
include FoxTails

class OutputWindow < FXMainWindow
  observable :mydata

  def initialize(app, projName)
    createWindow(app, projName)
  end

  def createWindow(app, projName)
    @app = app
    @outputdlg = FXDialogBox.new(app, projName, DECOR_ALL, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0)

    outputText = FTTextField.new(@outputdlg, 20, self, :mydata)
    outputText.dynamic = true
  end

  def create
    @outputdlg.create
    @outputdlg.position(200, 30, 150, 20)
    @outputdlg.show(PLACEMENT_DEFAULT)
  end
end

class TestWindow < FXMainWindow

  observable :outp, :locdata

  def initialize(*args)
    super

    inputText = FTTextField.new(self, 20, self, :locdata)
    inputText.dynamic = true

    outputText = FTTextField.new(self, 20, self, :locdata)
    outputText.dynamic = true

  end

  def create
    super
    position(0, 30, 150, 60)
    show(PLACEMENT_DEFAULT)
    @outp = OutputWindow.new(self, "Output")
    @outp.create
    @outp.when_mydata CHANGES do
      self.locdata = @outp.mydata
    end
    when_locdata CHANGES do
      @outp.mydata = @locdata
    end
  end
end

class TestApp < FTApp
  def initialize
    super("Test", "TEST")
    TestWindow.new(self, "Test")
  end
end

TestApp.new.run
