>> Dear fellow developers,
>>
>> When I clicked a component for instance a button, the event handler code 
>> as in below appears under Source tab. Could anyone please explain to me 
>> how it works and why does the action_Performed method appear two times, 
>> once by itself as a method and then another time under a class unknown to 
>> me called actionAdapter? All I want to do is just code one event handler 
>> that handles all button clicks, like so:
>> public void button_actionPerformed(ActionEvent e, Object arg);
>> {   ...... etc  }
>>
>> Here's theh code generated by JBuilder when I double-clicked a button:
>> public void jButton10_actionPerformed(ActionEvent e) {
>>    }
>> }
>>
>> class Frame2_jButton10_actionAdapter implements ActionListener {
>>    private Frame2 adaptee;
>>    Frame2_jButton10_actionAdapter(Frame2 adaptee) {
>>        this.adaptee = adaptee;
>>    }
>>
>>    public void actionPerformed(ActionEvent e) {
>>        adaptee.jButton10_actionPerformed(e);
>>    }
>> }
>>
>> Thanks in advance for explaining to me.
