An event handler contains lingo or javascript code which is executed when a particular event fires. An event handler always begins with "on" followed by the event name, and terminates with a sigle "end" (optionnaly followed by the event name).
Here's an example : Intercept a mouse click on a Sprite, and display a message box :
on mouseUp
alert("Hello world")
end
Animations or parents scripts can contain handlers subjected to be called from anywhere in a projection.
Behaviors scripts contain only handlers concerning events fired to a particular sprite (in the example above, the handler should be located in a behavior script attached to the clicked sprite.

The handler can be implemented with the use of an anonymous inner class. i.e. : button1.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { JOptionPane.showMessageDialog(null, "You clicked button1."); } });
