JButton Press (Not Release)

Question

I have a very small JButton called "b", which I want to do some things on click and not on release of it. I use the following code:

b.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e){
            //do some stuff
        }
    });

But what I realize is that it does the stuff I want as soon as the click is first pressed and then released. How can this be done my way? Thank you

Answer 1

A click means that a button has been pressed and released. A click event is triggered when a button is clicked and only if the button is still armed(mouse within the bounds of the button) when mouse is released. To handle the pressed event, use the low-level MouseListener

btn.addMouseListener(new MouseListener() {

    @Override
    public void mousePressed(MouseEvent e) {
        //do some stuff
    }

    /*Override other methods*/

});

Or better use a MouseAdapter

btn.addMouseListener(new MouseAdapter() {

        @Override
        public void mousePressed(MouseEvent e) {
            //do some stuff
        }

        /*No need to override other methods, `MouseAdapter` already does it*/

    });
