Subject: Re: Qt4 not supported?

hello,

I have made a little change :

*********************************************
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)
		self.setCentralWidget(zone_centrale)
	
	end
	
end


app=Qt::Application.new(ARGV)
fenetre=Fen_princ.new()
fenetre.show
app.exec

**********************************************

and I have then this error :
