How does JBuilder decide which ActionAdapter to use?

[Chao-Jen Chen]

Hi,

I'm curious about the way that the visual designer of JBuilder decides
or picks up which action adapter to use when I double-click on a visual
component. For example, given that JBuilder is configured to take
anonymous adapters for event handling, when I double-click on a
JButton named jButton1, JBuilder generates the following
listener-registering codes inside jbInit().

<CODE>
jButton1.addActionListener(new ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent e) {
jButton3_actionPerformed(e);
}
});
</CODE>

I just wonder why JBuilder know that it should take ActionListener,
not any other interface or class, for the anonymous adapter to
implement or inherit.

The creators of the visual designers chose that as the "default"/most
likely interface to implement. Also, I guess Delphi etc. do the same
thing.

For other event sets, there is the "event" tab.
