wxruby users - Jun 2008 - xrc xrcsie new user question

I am doing something wrong or missing a step.  I am trying to get a
panel that I made in DialogBlocks to come up in wxRuby.  I made the XRC
and ran xrcise on it.  I am getting an error when trying to start it.

Ruby code:
begin
  require ''rubygems''
rescue LoadError
end

require ''wx''
include Wx
require ''bogus_panel.rb''


class BogusPanel < Bogus_panel
  def initialize(parent)
    super(parent)
  end#def initialize
end


class BogusFrame < Wx::Frame
  def initialize
    super
    BogusPanel.new(self).set_focus
  end#def initialize
end#end Class

class BogusApp < App
  def on_init()
    BogusFrame.new.show
  end
end

BogusApp.new.main_loop()


xrcsie generated code:


# This class was automatically generated from XRC source. It is not

Thanks for the report. You turned up a problem in wxRuby which means 
that the current version isn''t able to load a Wx::Panel subclass from
XRC.

I have fixed this in our source repository, but for now you could get 
round this by starting from a top-level window type of "Frame" in your
GUI editor, instead of Panel. In DialogBlocks, it should be 
straightforward to drag and drop your Panel layout into a new "Frame"
class.

You also missed a step, which is that you must set the "name" of the
XRC
class you''re loading to be Bogus_panel, instead of the default 
ID_PANEL1, as in the attachment you posted.

Thanks again
