Dynamically change jButton icon

Question

I have a program that detects when certain machines are online and creates a button with a green \"online\" icon to show this. I want to add the functionality to check perio

Answer 1

you can add an action listener on the button, then in its called function change the icon - here is an example :

public yourDialogSwing() {

        Yourbutton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                onButtonPressed();
            }
        });
}

private void onButtonPressed() {
       YourButton.setIcon(YourButton.getPressedIcon());
}
