    	ta.setWrapStyleWord(true);
    	Container contentPane = frame_text.getContentPane();
    	contentPane.setLayout (new BorderLayout());
    	contentPane.add (tf,BorderLayout.NORTH);
      	contentPane.add (ta,BorderLayout.CENTER);
    	frame_text.pack();
    	frame_text.show();
    	frame_text.setResizable(false) ;     
  	frame_text.addWindowListener(new WindowAdapter()   {
        public void windowClosing(WindowEvent e) {
            System.exit(0); }
       });
