Well, you're certainly welcome to see it, though I'm not sure how much 
it will help you:


       def template(parent)
         raise "You must call super in initialize!" 
unless(defined?(@widgets))
         @real_parent = parent
         yield
       end

       def setup(name, &block)
         raise "Invalid widget name #{name}" unless(@widgets[name])
         @widgets[name].setup(&block)
       end

One thing that is key to the implementation is that I don't manipulate 
the real Fox widgets... instead, I wrap each one that I use and the 
final widgets only get built when I call build at the end of the create 
method. Here's the implementation for one widget wrapper:

       class TextField < Widget
         widget_attr :columns_visible => 1
         widget_attr :options => TEXTFIELD_NORMAL|LAYOUT_FILL_X

         widget_event :on_change, SEL_CHANGED
         widget_event :on_keypress, SEL_KEYPRESS

         def do_build(real_parent)
           FXTextField::new(real_parent, @columns_visible, nil, 0, 
@options)
         end
       end

Probably all I've really done is to tease you more... at some point I 
would like to release the utility, but I'm not doing Ruby much right 
now (new Java contract) so it may be a little while.

HTH,
