I shall try to tell my understanding (it is not an absolute truth):
"The delegation event model is more selective, delivering events only to components that indicate interest in the particular type of event by calling enableEvent(long) or adding a listener to the component."
Window.WINDOW_ICONIFIED event happens without any listener adding. It is because it is OS event, external to application. It is possible to mask/identify it, but not to prevent.
It is possible to catch iconization event but post-factum (minimization already happened) by

frame.addWindowListener ( new WindowAdapter()
{
   public void windowIconified(WindowEvent e)
   {
      //deiconify here, 
   }
}

and try to de-iconify then.
How to de-iconify? You should to communicate with external world/OS and solution will not be portable... I even do not know your OS...
Any other opinions?

There was similar but more active discussion earlier in this forum: http://www.javaranch.com/ubb/Forum2/HTML/002907.html

Having a (J)Dialog owned by your (Frame/JFrame) frame, will prevent minimization (but that dialog will be always on top and you may not even make it of "zero" size, peer's menubar, sorry taskbar, with close button will always show up:
<pre>
import java.awt.*;
import javax.swing.*;
public class TestDesactivateMinimize
{
public static void main (String args[])
{
javax.swing.JFrame frame = new javax.swing.JFrame ("JFrame");
//frame.pack();
JDialog diag = new JDialog (frame, "JDialog", true);
frame.setSize(200, 500);
frame.setLocation(500, 300);
frame.setVisible (true);
frame.show();
diag.show();
}
}
</pre>
