How can I check that JButton is pressed? If the isEnable() is not work?

Question

How can I check that JButton is pressed? I know that there is a method that its name is "isEnabled"

So I try to write a code to test.

1. this code have 2 Jbuttons which are "Add" Button and "Checkout" button.
2. the code will show the "Add button is pressed" message when I press "Checkout" button after I press "Add" button but If the "Add" Button is not pressed before the "Checkout" Button is pressed, the code will show the "Add Button is not pressed" message.

Here the code:

final JButton btnAdd = new JButton("Add");
btnAdd.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent arg0) {
    }
});
panel.add(btnAdd);
JButton btnConfirm = new JButton("Check Out");
btnConfirm.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        if (btnAdd.isEnabled()) {
            System.out.println("Add Button is pressed");
        }
        if (!btnAdd.isEnabled()) {
            System.out.println("Add Button is not pressed");
        }
    }
});

When I run this code,the code give only the " Add button is pressed" although I didn't press the "Add" Button. Why does it occur like that?

Answer 1

JButton has a model which answers these question:

• isArmed(),
• isPressed(),
• isRollOVer()

etc. Hence you can ask the model for the answer you are seeking:

     if(jButton1.getModel().isPressed())
        System.out.println("the button is pressed");

Answer 2

Seems you need to use JToggleButton :

JToggleButton tb = new JToggleButton("push me");
tb.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        JToggleButton btn =  (JToggleButton) e.getSource();
        btn.setText(btn.isSelected() ? "pushed" : "push me");
    }
});
