[armedbear-devel] anonymous inner class in abcl

[Patrice Seyed]

Right,

Hello abcl developers,

Let's say I want to implement an anonymous inner class, just for example
ActionListener with method actionPerformed:

JButton button = new JButton("Enter");
button.addActionListener(new ActionListener (){
public void actionPerformed(ActionEvent e){

System.out.println("The Enter button was pressed");
}
});

What is the best way to do this in abcl?


Cheers,
Patrice
