Subject: Re: Qt4 not supported?

hello,

thank you for your answer, ken.
I still have an error : here is my program :

    require ('Qt')

    class Fen_princ < Qt::MainWindow
       
        def initialize
            zone_centrale=Qt::Widget.new
            nom=Qt::LineEdit.new
            layout=Qt::FormLayout.new
            layout.addRow("Votre nom :",nom)
            zone_centrale.setLayout(layout)
            setCentralWidget(zone_centrale)                        
    <---- line 11
       
        end
       
    end



    app=Qt::Application.new(ARGV)
    fenetre=Fen_princ.new()                                       <-----
    line 19
    fenetre.show
    app.exec
