I have a main project GUI with tabs on it. these tabs have JPanels

classes that extend JPanel. the point of that is to make my code a
little cleaner. All the components in JPanel are private.
Seems familar.
However, I
don't know how to add an ActionListener to buttons and other components
on the JPanel and recieve these actions in the main project rather then
the JPanel class.
Me neither, so what I do instead is, have each panel implement
ActionListener and pass the panel a reference to the JFrame in it's
constructor, then the actionListener can invoke a method in the JFrame
to handle the event.
e.g. something not entirely unlike this
JPanel Foo extends JPanel implements ActionListener {
JFrame parent;
Foo(JFrame parent) {
this.parent = parent;
...
fooButton.addActionListener(this);
...
}
public void actionPerformed(ActionEvent e) {
parent.doCommand(e.getActionCommand());
}
}
