Forum: FXRuby windows in FxRuby

Hi to all,
I am new in ruby and very new in FxRuby.
I copied this little program from an example of fxruby:

equire 'fox16'
include Fox

class FinestraPrincipale < FXMainWindow
  def initialize(app)
  # Call the base class version of initialize
  super(app, "PROGRAMMA PIRAMIDE", :opts => DECOR_ALL, :x => 20, :y =>
20, :width => 600, :height => 400)
  # Menubar
  menubar = FXMenuBar.new(self, LAYOUT_SIDE_TOP|LAYOUT_FILL_X)
  filemenu = FXMenuPane.new(self)

  FXMenuCommand.new(filemenu, "Line 1")
  FXMenuCommand.new(filemenu, "Line 2")
  FXMenuCommand.new(filemenu, "Line 3")
  FXMenuCommand.new(filemenu, "Line 4")
  FXMenuCommand.new(filemenu, "Line 5")
  FXMenuCommand.new(filemenu, "Line 6")
  FXMenuCommand.new(filemenu, "Line 7")
  FXMenuCommand.new(filemenu, "Line 8")
  FXMenuSeparator.new(filemenu)
  FXMenuCommand.new(filemenu, "Line 9")
  FXMenuCommand.new(filemenu, "Information").connect(SEL_COMMAND) {
  FXMessageBox.information(self, MBOX_OK,"information", "info")
  }
  FXMenuSeparator.new(filemenu)
  FXMenuCommand.new(filemenu, "&Exit\tCtl-Z", nil, getApp(),
FXApp::ID_QUIT)
  FXMenuTitle.new(menubar, "&MAIN MENU", nil, filemenu)

  # Status bar
  status = FXStatusBar.new(self,
    LAYOUT_SIDE_BOTTOM|LAYOUT_FILL_X|STATUSBAR_WITH_DRAGCORNER)
  @clockLabel = FXLabel.new(status, Time.now().strftime("%I:%M:%S %p"),
nil,
    LAYOUT_FILL_Y|LAYOUT_RIGHT|FRAME_SUNKEN)
  end

  # Set choice
  def onCmdRadio(sender, sel, ptr)
    @choice = FXSELID(sel)
    return 1
  end

  # Update menu based on choice
  def onUpdRadio(sender, sel, ptr)
    sender.check = (FXSELID(sel) == @choice)
    return 1
  end

  # Create the main window and show it
  def create
    super
    show(PLACEMENT_SCREEN)

    # Create a thread to update the clock
    @clockThread = Thread.new(@clockLabel) { |clockLabel|
    while true
      clockLabel.text = Time.now.strftime("%I:%M:%S %p")
      sleep(1)
    end
    }
  end

end

if __FILE__ == $0
  # Make application
  application = FXApp.new("Groupbox", "FoxTest")
  # Make window
  FinestraPrincipale.new(application)
  #ProgrammaPiramide.new(application)
  # Create app
  application.create
  # Run
  application.run
end

this program only creates a main window on the screen with a menu bar.

But I am not able to create another window clicking on menu line 1; I
found a lot of examples calling dialog windows but no examples calling
another window to be populated with a new menubar.

Can someone help and tell me how to write instructions to make this
program?
Thank you

You need to raise an FXDialogBox when you click a button in the menu 
line.
