Question

till now i have constructed JFrames andJDialogs in my project , now i would like to give an option to print the same , using a button at teh bottom of teh frame or dialog...how can i do it .....????

Answer 1

1) create: class WFrame extends JFrame implements Printable
2) import
import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;
import java.lang.reflect.*;
import java.awt.datatransfer.*;
import java.io.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
import javax.swing.plaf.*;
import javax.swing.plaf.metal.*;
3) add these 3 methods to your class WFrame
     public void onPrint() throws PrinterException {
          PrinterJob printJob = PrinterJob.getPrinterJob();
          printJob.setPrintable(this);
          PageFormat pf = printJob.pageDialog(printJob.defaultPage());
          if (printJob.printDialog())
               printJob.print();
     public int print(Graphics g, PageFormat pg, int i) throws PrinterException {
          int no = 1; //getNumberOfPages();
          if (i>-1 && i<no) {
               g.translate((int)pg.getImageableX(), (int)(pg.getImageableY()+(pg.getImageableY()+pg.getImageableHeight())*i));
               g.setClip(0, 0, getSize().width, getSize().height);
               paint(g);
               return PAGE_EXISTS;
          return NO_SUCH_PAGE;
     public void onCaptureScreen(String filename) throws IOException, FileNotFoundException, AWTException {
          FileOutputStream file = new FileOutputStream(new File(filename));
          JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(file);
          Rectangle rectangle = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
          encoder.encode(new Robot().createScreenCapture(rectangle));
          file.close();
4) make code to call thoses methods
