3 Interactors

4

5 JSlider slide = new JSlider(min, max, initial); JButton button = new JButton( [button text] ); JTextField field = new JTextField( [field text] );

6 JSlider slide = new JSlider(min, max, initial); JButton button = new JButton( [button text] ); JTextField field = new JTextField( [field text] ); add(interactor, location);

8 addactionlisteners();

9 addactionlisteners(); public void actionperformed(actionevent e) { }

10 addactionlisteners(); public void actionperformed(actionevent e) { if (e.getsource() == someinteractorivar) {!!...! } }

11 addactionlisteners(); public void actionperformed(actionevent e) { if (e.getsource() == someinteractorivar) {!!...! requires instance variables } }

12 addactionlisteners(); public void actionperformed(actionevent e) { if (e.getsource() == someinteractorivar) {!!...! requires instance variables } if (e.getactioncommand().equals( [text in button] )) {!!...! } }

13 addactionlisteners(); public void actionperformed(actionevent e) { if (e.getsource() == someinteractorivar) {!!...! requires instance variables } } if (e.getactioncommand().equals( [text in button] )) {!!...! } only works for buttons unless you use someinteractor.setactioncommand( [action command] )
