Subject: Re: Dynamically changing widgets in FXRuby

Example at hand:
#--- snip here ---#
 require 'fox'
 include Fox
 class MainWindow < FXMainWindow
   def draw_display
     @tree = FXTreeList.new([snip])
     @tree.create
     @one = @tree.addItemLast([snip])
     [snip]

Yes!  Thank you so very much!  What I was missing was the 'create' method.
Now that I know that is the "magic" function which makes things appear on
the screen and see that there are indeed a couple of examples in FXRuby
that show how this works, but I overlooked them because I did not understand.

But thank you very much for helping me.  I now can do what I had hoped to
do in FXRuby, which is create a user interface on the fly based on input
files known only at runtime! =)
