Subject: QtRuby - Error

Hello,
I new in the ruby world.
Sorry my english, i'm argentino and speak spanish.

My question is about QtRuby. Where can tutorials, Faq, Qt's Classes?.
Qt4 work with ruby or only Qt3?
I' design form with Qt4-designer and:

rbuic mainWindow.ui > mainWindow.rb

##################################################################
ggerman@comandante:~/Qt4/example$ cat mainWindow.rb
# Form implementation generated from reading ui file 'mainWindow.ui'

require 'Qt'
class MainWindow < Qt::MainWindow
    def initialize(parent = nil, name = nil, fl = WType_TopLevel)
        super
        statusBar()
        setCentralWidget(Qt::Widget.new(self, "qt_central_widget"))
        @Widget = Qt::Widget.new(centralWidget(), "Widget")
        @MenuBar.setProperty( "geometry", Qt::Variant.new(Qt::Rect.new(0, 0, 
409, 29) ) )
        @StatusBar = Qt::StatusBar.new(centralWidget(), "StatusBar")
        languageChange()
        resize( Qt::Size.new(409, 580).expandedTo(minimumSizeHint()) )
        clearWState( WState_Polished )
    end
    #
    #  Sets the strings of the subwidgets using the current
    #  language.
    #
    def languageChange()
        setProperty("windowTitle", Qt::Variant.new(trUtf8("MainWindow")))
    end
    protected :languageChange
end
if $0 == __FILE__
    a = Qt::Application.new(ARGV)
    w = MainWindow.new
    a.mainWidget = w
    w.show
    a.exec
end
##################################################################

mainWindow.rb:24:in `initialize': undefined method `setProperty' for 
nil:NilClass (NoMethodError)
        from mainWindow.rb:47:in `new'
        from mainWindow.rb:47

Thank you for you help.
