Can I add an action listener to a JLabel?
Add a MouseListener
to the JLabel
.
Because JLabel
is a Component
, you can add MouseListener
s to it. Use that interface and write the mouseClicked
event on your MouseListener
to handle the click.
An easier approach is to just use a JButton since it already supports this functionality by using an ActionListener.
You can make the JButton look like a JLabel by using:
button.setBorderPainted( false );
This approach is for when you want to handle a mouseClick, since an ActionEvent is guaranteed to be generated, whereas as mouseClicked event when using a MouseListener may not be generated in all situations, which can confuse the user.
/*add a mouselistener instead and listen to mouse clicks*/
jlable.addMouseListener(new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
System.out.println("Yay you clicked me");
}
});
Sure. JLabels have a method which allow you to attach a MouseListener object. The MouseListener object requires a MouseAdapter() object. MouseAdapter is an abstract class which ideally serves as an Adapter for for creating on the fly listeners to do things.
JLabel lb = new JLabel(An image icon, if you'd like.);
//now lets attach a listener to your JLabel
lb.addMouseListener(new MouseAdapter()
{
@Override
public void mouseClicked(MouseEvent e)
{
//THIS CODE WILL RUN WHEN THE EVENT OF CLICKING IS RECEIVED.
//example of something you could do below.
new Random().ints().limit(60).forEach(System.out::println);
}
});
