JTable printing problem
hello, i m using the following code to print the JTable.
import java.awt.*;
import javax.swing.*;
import java.awt.print.*;
public class PrintUtilities implements Printable {
private Component componentToBePrinted;
public static void printComponent(Component c) {
new PrintUtilities(c).print();
}
public PrintUtilities(Component componentToBePrinted) {
this.componentToBePrinted = componentToBePrinted;
}
public void print() {
PageFormat pageFormat=new PageFormat();
Paper paper = pageFormat.getPaper();
paper.setImageableArea(0, 0.5D*72, 8.267D*72, 10.692D*72);
paper.setSize(8.267D*72, 11.692D*72);
pageFormat.setPaper(paper);
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintable(this);
if (printJob.printDialog())
try {
printJob.print();
} catch(PrinterException pe) {
System.out.println("Error printing: " + pe);
}
}
public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
if (pageIndex > 0) {
return(NO_SUCH_PAGE);
} else {
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
disableDoubleBuffering(componentToBePrinted);
componentToBePrinted.paint(g2d);
enableDoubleBuffering(componentToBePrinted);
return(PAGE_EXISTS);
}
}
/** The speed and quality of printing suffers dramatically if
* any of the containers have double buffering turned on.
* So this turns if off globally.
* @see enableDoubleBuffering
*/
public static void disableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(false);
}
/** Re-enables double buffering globally. */
public static void enableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(true);
}
}
//******************************//
PrintUtilities.printComponent(table);
Its printing the data in the JTable properly n correctly, but its not printing the column names or the column heads in the print-out.
Plz help me.
Thanks in advance.
