I have two JButtons
called "Left" and "Right".
The "Left" button moves a rectangle object to the left and the "Right" button moves it to the right.
I have one ActionListener
in the class that acts as the listener for when either button is clicked.
However I want different actions to happen when each are clicked. How can I distinguish, in the ActionListener
, between which was clicked?
Set actionCommand to each of the button.
// Set the action commands to both the buttons.
btnOne.setActionCommand("1");
btnTwo.setActionCommand("2");
public void actionPerformed(ActionEvent e) {
int action = Integer.parseInt(e.getActionCommand());
switch(action) {
case 1:
//doSomething
break;
case 2:
// doSomething;
break;
}
}
UPDATE:
public class JBtnExample {
public static void main(String[] args) {
JButton btnOne = new JButton();
JButton btnTwo = new JButton();
ActionClass actionEvent = new ActionClass();
btnOne.addActionListener(actionEvent);
btnTwo.addActionListener(actionEvent);
btnOne.setActionCommand("1");
btnTwo.setActionCommand("2");
}
}
class ActionClass implements ActionListener {
@Override
public void actionPerformed(ActionEvent e) {
int action = Integer.parseInt(e.getActionCommand());
switch (action) {
case 1:
// DOSomething
break;
case 2:
// DOSomething
break;
default:
break;
}
}
}
