actionPerfomed

Can actionPerfomed method be called directly? also can any user-defined object use addActionListener to get an event listener? Thank you.

Hi Tom,
It depends on how you defined your actionPerformed. If you used an anonymous class you are out of luck. If you just have an actionPerformed method in your class that uses a switch statement or if/then to figure out which source called it then you can go ahead and call it after you create an ActionEvent object containing useful information.
If you used Anonymous classes you will need to perform something like the following.

//
// Create an action event using whatever source you want.
//  I have used 'c' here for the component.
//
ActionEvent ae = new ActionEvent( c, ActionEvent.ACTION_PERFORMED, "" );
//
// Slam the action event into the system event queue.
//
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent( ae );

To use addActionListener, the user-defined object will need to subclass an AWT class that defines it. Otherwise you will need to define it yourself. Your user-defined object will have to be subclass in AWT or you are really wasting your time!

Manfred.
