I am having trouble with the frame icon in my
application. I am using setIconImage() in the
constructor for my class. It functions properly
until I destroy() any frame using the image.
Then, the icon doesn't show up when the next
new window is constructed. I am using
Toolkit.getDefaultToolkit().getImage("Moto.gif")
to get the image.

It also seems to be returning the same image
object each time I call the above getImage()
method. It must be buffering the image for
multiple uses.

I am using JDK 1.1.4 on Windows 95.

Any help would be appreciated.


// This test program will show a problem with setting the icon image.
// To duplicate, click the "Create New Window" button, then close the window
// after that point, with any new window openings, the icon will fail to load

import java.awt.*;
import java.awt.event.*;

public class FrameTest extends Frame implements WindowListener,ActionListener
{
    static int instances = 0;

    public static void main(String args[])
    {
        FrameTest f = new FrameTest();

        f.show();
    }

    public FrameTest()
    {
        // set the layout manager
        setLayout(new FlowLayout(FlowLayout.CENTER));

        // set the default icon
        setIconImage(getMyIconImg());

        // listen for window events
        addWindowListener(this);

        Button b1=new Button("Create New Window");
        add("South",b1);
        b1.addActionListener(this);

        instances++;

        pack();
    }

    private final Image getMyIconImg()
    {
        return( Toolkit.getDefaultToolkit().getImage("Moto.gif") );
    }

    public void actionPerformed(ActionEvent ev)
    {
        String sel = ev.getActionCommand();

        if (sel == "Create New Window")
        {
            FrameTest f = new FrameTest();
            f.show();
        }
    }

    public void windowDeactivated(WindowEvent event)

    public void windowOpened(WindowEvent event)

    public void windowClosing(WindowEvent e)
    {
        instances--;
        if (instances == 0)
        {
            System.exit(1); // exit the program
        }
        else
        {
            dispose(); // call dispose to terminate the window
        }
