JTextPane help

Use this code to print your text pane component:

import java.awt.*;

import java.awt.print.*;

/**

* This wrapper class encapsulates a Component and allows it to be printed

* using the Java 2 printing API.

*/

public class PrintableComponent implements Printable {

// The component to be printed.

Component c;

/** Create a PrintableComponent wrapper around a Component */

public PrintableComponent(Component c) { this.c = c; }

/**

* This method is not part of the Printable interface. It is a method

* that sets up the PrinterJob and initiates the printing.

*/

public void print() throws PrinterException {

// Get the PrinterJob object

PrinterJob job = PrinterJob.getPrinterJob();

// Get the default page format, then allow the user to modify it

PageFormat format = job.pageDialog(job.defaultPage());

// Tell the PrinterJob what to print

job.setPrintable(this, format);

// Ask the user to confirm, and then begin the printing process

if (job.printDialog())

job.print();

}

/**

* This is the "callback" method that the PrinterJob will invoke.

* This method is defined by the Printable interface.

*/

public int print(Graphics g, PageFormat format, int pagenum) {

// The PrinterJob will keep trying to print pages until we return

// this value to tell it that it has reached the end.

if (pagenum > 0)

return Printable.NO_SUCH_PAGE;

// We're passed a Graphics object, but it can always be cast to Graphics2D

Graphics2D g2 = (Graphics2D) g;

// Use the top and left margins specified in the PageFormat Note

// that the PageFormat methods are poorly named. They specify

// margins, not the actual imageable area of the printer.

g2.translate(format.getImageableX(), format.getImageableY());

// Tell the component to draw itself to the printer by passing in

// the Graphics2D object. This will not work well if the component

// has double-buffering enabled.

c.paint(g2);

// Return this constant to tell the PrinterJob that we printed the page.

return Printable.PAGE_EXISTS;

}

}

example:

Printable printable = new PrintableComponent(yourTextPane);

printable.print();
