The windowDeactivated() never called for java.awt.Window objects. Try the attached example.
1. compile it.
2. run it.
3. shows a frame with "Show/Hide" button, click on it.
4. Click on it.
5. A window appears. Click on it.
6. The "Frame deactivated" message on stdout.
7. No "Window Activated" message on stdout.

Now comment the lines which declare JWindow and uncomment lines which declare JDialog. Now -

1. compile it.
2. run it.
3. shows a frame with "Show/Hide" button, click on it.
4. Click on it.
5. A dialog appears. Click on it.
6. The "Frame deactivated" message on stdout.
7. The "Window Activated" message on stdout.

This proves that WINDOW_ACTIVATED and WINDOW_DEACTIVATED events are not generated for java.awt.Window objects but is generated for Frame and Dialog
subclasses. Here is the snippet from API Javadoc -

windowActivated

 public abstract void windowActivated(WindowEvent e)

Invoked when a window is activated.

windowDeactivated

 public abstract void windowDeactivated(WindowEvent e)

Invoked when a window is de-activated.

My java -version yields -

java version "1.1.6"

the java.awt.Window object only generates windowOpened and windowClosed... but nothing else.

this is the blurb from the JavaDocs:
"Windows are capable of generating the following window events: WindowOpened, WindowClosed. "

At the very least, it should get activated and deactivated... java.awt.Window is the only component of its type that doesn't show a title bar, and so tends to become a work-horse of may applications.
