>>> 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.
