Swing and AWT Problem
0 Answer(s)      4 years and 5 months ago
Posted in : Swing AWT

hi sir i have a problem i know from one Jframe we can send values to another Jframe.

so in my project i have one fame containing three textfields
String a=TNa.getText().toString();
String b=TCo.getText().toString();
String c=TCl.getText().toString();

applicationclient1.DrawingCanvas obj=new applicationclient1.DrawingCanvas();

applicationclient1.AnotherPrintDemo mn=new applicationclient1.AnotherPrintDemo();

and another Frame is

public class AnotherPrintDemo extends JFrame {
DrawingCanvas canvas;

JButton setUpButton = new JButton("Page Setup");

JButton printButton = new JButton("Print");

JButton cancelButton = new JButton("Cancel");

public AnotherPrintDemo() {
Container container = getContentPane();

canvas = new DrawingCanvas();

JPanel panel = new JPanel(new GridLayout(1, 3));

ButtonListener buttonListener = new ButtonListener();



container.add(BorderLayout.SOUTH, panel);

addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
setSize(520, 500);

class ButtonListener implements ActionListener {
PrinterJob printJob;

PageFormat pageFormat;

PrintableCanvas printableCanvas;

ButtonListener() {
printJob = PrinterJob.getPrinterJob();
pageFormat = printJob.defaultPage();

public void actionPerformed(ActionEvent e) {
JButton tempButton = (JButton) e.getSource();

if (tempButton.equals(setUpButton)) {
pageFormat = printJob.pageDialog(pageFormat);
} else if (tempButton.equals(printButton)) {
printableCanvas = new PrintableCanvas(pageFormat);

boolean ok = printJob.printDialog();
if (ok) {
try {
} catch (Exception pe) {
System.out.println("Printing Exception Occured!");
} else if (tempButton.equals(cancelButton)) {
applicationclient1.NewJFrame mn=new applicationclient1.NewJFrame();


public static void main(String arg[]) {
new AnotherPrintDemo();

class DrawingCanvas extends JPanel {
Font font;
String Na;
String Co;
String Cl;
FontMetrics fontMetrics;

int w, h;

DrawingCanvas() {
setSize(500, 470);

w = this.getWidth();
h = this.getHeight();

font = new Font("Dialog", Font.BOLD, 12);
fontMetrics = getFontMetrics(font);

public void paintComponent(Graphics g) {
Graphics2D g2D = (Graphics2D) g;

paintContent(g2D, w, h);

public void paintContent(Graphics2D g2D, int w, int h) {
g2D.drawRoundRect(70, 70,350,280,10,10);
g2D.drawLine(70,120 ,420,120);
g2D.drawLine(320, 120, 320, 350);
g2D.drawLine(70, 305, 420, 305);
g2D.drawString("NAME :", 75,90);
g2D.drawString(Na,125 ,90);
g2D.drawString("COURSE :",75 ,115 );
g2D.drawString(Co,135, 115);
g2D.drawString("CLASS :",270, 115);
g2D.drawString(Cl,320 ,115);
g2D.drawString("Amount :", 75,160);
g2D.drawString("Balance :", 75,200);
g2D.drawString("Total :", 75,300);
g2D.drawString("Recieved :", 75,330);


class PrintableCanvas implements Printable {
DrawingCanvas canvas;

PageFormat pageFormat;

public PrintableCanvas(PageFormat pf) {
pageFormat = pf;

public int print(Graphics g, PageFormat pageFormat, int pageIndex)
throws PrinterException {
if (pageIndex >= 1) {
return Printable.NO_SUCH_PAGE;

Graphics2D g2D = (Graphics2D) g;

canvas = new DrawingCanvas();

canvas.paintContent(g2D, (int) pageFormat.getImageableWidth(),
(int) pageFormat.getImageableHeight());

// successful printing of the page
return Printable.PAGE_EXISTS;

so i want to send those three textfields values to the next frame into
g2D.drawString(Na,125 ,90);
g2D.drawString(Co,135, 115);
g2D.drawString(Cl,320 ,115);

how can i get those textfields values to these three String variable
please reply cir as much as possible i have to submit my project within four days
