Question

I have a small template that ive built for the purpose of implementing an applet through a simple java application via netbeans 7.1 (as in not using Javacard, Netbeans Platform etc ..just a simple java application with applet initialized when application runs)

I have managed to make it invoke the applet when i press the run button in netbeans and i ahve functionality inside the applet but, i cant seem to get it to close and i have a horrible feeling people are gonna tell me to have used jFrame and implement the EXIT_ON_CLOSE method.

This is NOT something I would like to know how to do , my mission is to implement it using Frames != jFrames.
I hope someone can help as its bugged me for a bit now and i have to get on with Java assignment that involves its use.

Enclosed is the code/classes for A: the appletframe and B:the applet

    * 1.4   Write an applet to display a line of text. 
    * The text should then change its font size and style (bold, italic, underline) 
    * depending on where the mouse is clicked on the screen.
    */
   package appletframe;
   import java.awt.Graphics;
  import java.awt.Frame;
 import java.applet.Applet;

  /**

  */

  import java.awt.*;

  public class AppletFrame extends Applet{

 public static void main(String[] args) {

/*construct needs object instances*/
MrApplet mrApplet = new MrApplet(); // create instance/obj of MrApplet 
Frame myFrame = new Frame("Applet"); // create frame "title optional"
//setDefaultCloseOperation(myFrame.EXIT_ON_CLOSE);(jFrame- not wanted)

/* add applet to the frame*/
//myFrame.addWindowListener();
myFrame.add(mrApplet, BorderLayout.CENTER);
myFrame.setBounds(10,10,500,500);
myFrame.setVisible(true); // step to make frame visible

/*initialize instance of mrApplet*/
mrApplet.init();
} // end main
} // end class

B: applet

   package appletframe;

import java.awt.*; //for buttons
import java.awt.event.*; //for events
import java.applet.*; //main applet api`s
import java.awt.Graphics; //graphics

public class MrApplet extends Applet implements ActionListener
{

private static final long serialVersionUID = 1L;
Button btnClick;
String msg = "";

public void init() 
{
    // TODO start asynchronous download of heavy resources
    setSize(500, 500);
    Button btnClick = new Button("Press Me ");
    btnClick.addActionListener(this);
    add(btnClick);
}
public void actionPerformed(ActionEvent e) 
{
    //throw new UnsupportedOperationException("Not supported yet.");
    msg = "Yay, the button works";
            repaint();
}     
public void paint (Graphics g)
{
    g.setFont(new Font("Serif", Font.ITALIC, 30)); //new font obj, font , font style, font size
    g.setColor(new Color(0,255,0)); //new color obj, r,g,b
    g.drawString(msg, 40, 80); 

}  
// TODO overwrite start(), stop() and destroy() methods
}

Once again thanks for reading, and to clarify any confusions..
I am looking for a pointer as to the solution of closing my applet and frame window upon exit , without reimplementing it all using jFrame, though i know this would be easier in the first instance.
Thankyou and as always, indebted to all your advice.

Answer 1

add this line at the end of ApplicationFrame class.

myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

You want to do it with Frame not with JFrame, then you have to add the WindowListener event to the frame and have to override windowClosing() method.

myFrame.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent we){
   System.exit(0);
});
