printing in java
hey guys, I want to make a class that sends all the contests of a frame to a printer. Am currently using the code below but it only prints the visible contents. how can i modify it?
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.print.*;
public class Printer implements Printable, ActionListener {
//JFrame frameToPrint;
JScrollPane pane;
//public Printer(JFrame f) {
public Printer(JScrollPane p) {
pane = p;
}
public int print(Graphics g, PageFormat pf, int page) throws
PrinterException {
if (page > 0) { /* We have only one page, and 'page' is zero-based */
return NO_SUCH_PAGE;
}
/* User (0,0) is typically outside the imageable area, so we must
* translate by the X and Y values in the PageFormat to avoid clipping
*/
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
/* Now print the window and its visible contents */
//frameToPrint.printAll(g);
pane.printComponents(g);
/* tell the caller that this page is part of the printed document */
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) {
/* The job did not successfully complete */
}
}
}
public static void main(String args[]) {
UIManager.put("swing.boldMetal", Boolean.FALSE);
JFrame f = new JFrame("Print UI Example");
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});
JTextArea text = new JTextArea(50, 20);
for (int i=1;i<=100;i++) {
text.append("Line " + i + "\n");
}
JScrollPane pane = new JScrollPane(text);
pane.setPreferredSize(new Dimension(250,200));
f.add("Center", pane);
JButton printButton = new JButton("Print This Window");
printButton.addActionListener(new Printer(pane));
f.add("South", printButton);
f.pack();
f.setVisible(true);
}
}
