When you create controls dynamically, don't forget to call "create",
like this:

require 'fox16'
include Fox

class Lookup < FXMainWindow
def initialize(app)
super(app, "Lookup window", :width=>400, :height=>600,
:opts => DECOR_ALL|LAYOUT_FILL_X|LAYOUT_FILL_Y)
bframe = FXHorizontalFrame.new(self, :opts => LAYOUT_FILL_X)
hearButton = FXButton.new(bframe, "Do you hear me?")
hearButton.connect(SEL_COMMAND) do |sender,sel, data|
@yesWindow = FXHorizontalFrame.new(self, :opts =>
FRAME_GROOVE|LAYOUT_FILL_X)
yesLabel = FXLabel.new(@yesWindow,"Yes")
@yesWindow.create
self.recalc
@yesWindow.show
puts "pushed hear button"
puts "window shown? " + @yesWindow.shown?.to_s
end
end

def create
super
show(PLACEMENT_SCREEN)
end

end

if __FILE__ == $0
FXApp.new do |app|
Lookup.new(app)
app.create
app.run
end
End
