== Shell Events ==

<p>Shells can generate a unique type of event: shell events (ShellEvent).
A shell event is generated when a shell is minimized, maximized, activated, deactivated, or closed.</p>
<p>To add a shell listener to a shell, use this method:</p>



<source lang="java">
public void addShellListener(ShellListener listener)</source>
