Short answer: use #retarget. This is a method of all the FTTargeted 
widgets. Sorry about the docs...

Long answer below. This will be in the examples dir in the next FoxTails 
release.

==== disconnect.rb ====
#!/usr/bin/env ruby

require 'foxtails'

include Fox
include FoxTails

class MainWindow < FXMainWindow
   observable :data, :t2, :t3

   def initialize(*args)
     super

     self.t2 = true
     self.t3 = true

     frame = FXVerticalFrame.new(self)

     f1 = FXHorizontalFrame.new(self)
     FXLabel.new(f1, "One", nil, LAYOUT_FIX_WIDTH).width = 50
     @text1 = FTTextField.new(f1, 60, self, :data)
     @text1.dynamic = true

     f2 = FXHorizontalFrame.new(self)
     FXLabel.new(f2, "Two", nil, LAYOUT_FIX_WIDTH).width = 50
     @text2 = FTTextField.new(f2, 60, self, :data)
     @text2.dynamic = true
     @check2 = FTCheckButton.new(f2, "connected to One", self, :t2)
     when_t2 CHANGES do |val|
       @text2.retarget(val ? self : nil)
     end

     f3 = FXHorizontalFrame.new(self)
     FXLabel.new(f3, "Three", nil, LAYOUT_FIX_WIDTH).width = 50
     @text3 = FTTextField.new(f3, 60, self, :data)
     @text3.dynamic = true
     @check3 = FTCheckButton.new(f3, "connected to One", self, :t3)
     when_t3 CHANGES do |val|
       @text3.retarget(val ? self : nil)
     end

   end

   def create
     super
     show(PLACEMENT_OWNER)
   end
end

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

TestApp.new.run
