MRJ Preferences Handler

In addition to the MRJAboutHandler and MRJQuitHandler present in the previous release of Java, this release includes the MRJPrefsHandler. This allows your Java application’s preferences panel to be opened from the Application Menu. To take advantage of this additional functionality you need to:

Import com.apple.mrj.MRJPrefsHandler

Implement the MRJPrefsHandler interface

Define a handlePrefs() method with a return type of void. This method will be called when a user selects About YourApplicationName from the Application Menu. In this method you should display your preferences panel.

The MRJPrefsHandler behaves like the MRJAboutHandler and the MRJQuitHandler. Examples of their usage can be found in a new Project Builder Java Swing Application.
