ho ft in modo diverso... ti faccio vedè


import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;
import javax.swing.*;

public class PrintTestFrame extends JFrame implements ActionListener, Printable
{


CalcolaCod x=new CalcolaCod();
x.ritFrame();/// RITORNA IL FRAME PRINCIAPALE DA STAMPARE
private PrinterJob job;
private JButton buttonPrint;



public PrintTestFrame ()
{


job=PrinterJob.getPrinterJob();
job.setPrintable (this);
}

public void actionPerformed (ActionEvent ae)
{
if (job.printDialog ())
{
try {
job.print ();
} catch (Exception e) {
JOptionPane.showMessageDialog (this, "Errore");
}
}
}

public int print (Graphics g, PageFormat pageFormat, int pageIndex)
{
if (pageIndex > 0)
return NO_SUCH_PAGE;

double imageableWidth = pageFormat.getImageableWidth ();
double imageableHeight = pageFormat.getImageableHeight ();

double frameWidth = getWidth ();
double frameHeight = getHeight ();

double scale = imageableWidth / frameWidth; // Modo "Fit width"

Graphics2D g2d = (Graphics2D) g;
g2d.translate (pageFormat.getImageableX (), pageFormat.getImageableY ());
g2d.scale (scale, scale);

printAll (g); // Invoca printAll sul frame (this)

return PAGE_EXISTS;
}

public static void main (String[] args)
{
SwingUtilities.invokeLater (new Runnable ()
{
public void run ()
{
PrintTestFrame f = new PrintTestFrame ();
f.setVisible (true);
}
});
}
}

ora il mio problema è assegnare al frame d qst classe ...il frame di ritorno, è quindi possibile che un frame prenda un frame?
