awt window not closing when close button is clicked

Question

I implemented a sample class for a Virtual KeyBoard and ran this VirtualKeyboardTest.The keyboard appears but the main problem is that it is not closing properly when the x button is clicked.How can i rectify this? ``` import java.awt.*; import java.awt.event.*; public class VirtualKeyboardTest { public static void main(String args[]) { VirtualKeyboard vk = new VirtualKeyboard(); vk.setSize(500,300); vk.setVisible(true); Frame f1 = new Frame(); f1.addWindowListener( new WindowAdapter() { @Override public void windowClosing(WindowEvent we) { System.exit(0); } } ); } } ```

Accepted Answer

You code is incorrect. Instead of

```
f1.addWindowListener( new WindowAdapter() {
  ...
```

try

```
vk.addWindowListener( new WindowAdapter() {
  ...
```

This will close your window.
