Question

After advice from another thread, I’ve been playing with the timer class without much joy. Heres my code:

 public void buttonImageReveal(ActionEvent e){

        Timer gameTimer = new Timer(100, new ActionListener() {

            public void actionPerformed(ActionEvent e) {

              repaint();
            }
          });

        String temp = e.getActionCommand();

        switch(temp){
                        case "1":
                            System.out.println("case1");                            
                            ((JButton)e.getSource()).setIcon(one);
                            gameTimer.start();
                            ((JButton)e.getSource()).setIcon(null);
                            break;

All I want is a 1 second gap between the image one been shown as the icon then that been removed. Only to happen once when the button is click. At the moment I just get a blank button when pressed?

TIA

Edit:

     public void actionPerformed(ActionEvent e) {
          System.out.println(e);
          lastImage();

        }

      });

public void buttonImageReveal(ActionEvent e){ 

        String temp = e.getActionCommand();

        switch(temp){
                        case "1":                       
                            ((JButton)e.getSource()).setIcon(one); 
                            lastBtn = ((JButton)e.getSource()); 
                            gameTimer.start();

                            break;

It now doing what it should, but the timer keeps going and going, what do you do to once your finished and want it to stop?!

Answer 1

You set the icon, start a timer and then immediately remove the icon. The start() method from the timer is almost immediately going to return and the timer will perform its task asynchronously. You’ll need to do the icon removing in the actionPerformed method.
