Print Text

[Marcus Senna]

I am trying to print the text in a JTextArea, which is in a JScrollPane. Right now i am only able to print what is viewable in the JScrollPane. I would like to print all of the text in the JTextArea. Below is the code i have been using. Thanks!!

    
public class SimulationResults extends JFrame implements ActionListener,
      Printable {
 
    ResultText newContentPane;
    JButton print;
    public SimulationResults() {
 
      this.setTitle("Simulation Results");
      this.setSize(700, 400);
      Dimension frameSize = this.getSize();
      Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
      int centerX = screenSize.width / 2;
      int centerY = screenSize.height / 2;
      int halfWidth = frameSize.width / 2;
      int halfHeight = frameSize.height / 2;
      this.setLocation(centerX - halfWidth, centerY - halfHeight);
 
      this.getContentPane().setLayout(new BorderLayout());
      this.setBackground(Color.WHITE);
      this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
      ;
      print = new JButton("Print");
      print.addActionListener(this);
      newContentPane = new ResultText();
      newContentPane.setOpaque(true); 
      this.getContentPane().add(newContentPane, BorderLayout.CENTER);
      this.getContentPane().add(print, BorderLayout.SOUTH);
    }
 
    public ResultText getNewContentPane() {
      return newContentPane;
    }
 
    public int print(Graphics g, PageFormat pf, int page) throws
        PrinterException {
      if (page > 0) {
        return NO_SUCH_PAGE;
      }
      Graphics2D g2d = (Graphics2D) g;
      g2d.translate(pf.getImageableX(), pf.getImageableY());
 
      this.getContentPane().getComponent(0).print(g);
      return PAGE_EXISTS;
    }
 

    public void actionPerformed(ActionEvent e) {
      PrinterJob job = PrinterJob.getPrinterJob();
      job.setPrintable(this);
      boolean ok = job.printDialog();
      if (ok) {
        try {
          job.print();
        } catch (PrinterException ex) {
 
        }
      }
    }
 
    public class ResultText extends JPanel {
      JTextArea textArea;
      JScrollPane scrollPane;
      private final static String newline = "\n";
      public ResultText() {
        super(new GridBagLayout());
        textArea = new JTextArea(5, 20);
        textArea.setEditable(false);
        scrollPane = new JScrollPane(textArea,
                                     JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
                                     JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
        GridBagConstraints c = new GridBagConstraints();
 
        c.fill = GridBagConstraints.BOTH;
        c.weightx = 1.0;
        c.weighty = 1.0;
        add(scrollPane, c);
        //textArea.removeAll();
 
      }
 
      public void writeTextArea(String string) {
        textArea.append(string + newline + newline);
        textArea.setCaretPosition(textArea.getDocument().getLength());
 
      }
    }
  }

Is this possible to print the value inside JTextArea without using setText() or writeTextArea method??

[Marcus Senna]

The writeTextArea method is called by an object of my system, to display the status of that object on the JTextArea.
