Java Apllet button problem

    im new to java and im wondering if someone could just quickly show me how i can have me button on the applet to perform an event when i click it. i'm having no luck with the EventHandler sample code off the net.

    the way im doing it is i create the button like:

    button play;
    play=new button("play");
    this.add(play);

    i then put in
    play.addActionListener(this);
    but it told me it couldn't put it in my applet!

    also, there is a
    public boolean event(Event event, Object arg)
    thing there too.

    any help?
    thanks

    this is the init() functin at the start. im not sure if all this stuff is meant to go in here or not so...
            public void init()
    		{
    		// method typically for initializing fields, creating GUI components,
    		//  loading sounds to play, loading images to display & creating threads
    
    
                    Button play_button;
                    Button Card1_button;
                    Button Card2_button;
                    Button Bet_button;
                    Button Check_button;
                    Button Fold_button;
                    Choice Bets;
                    
                    JButton play_game;
    
    	
    	   // add buttons here
    	   play_button = new Button("Play");
    	   play_button.setForeground(Color.black);
    	   play_button.setBackground(Color.lightGray);
    	   this.add(play_button);
                    play_button.addActionListener(this);
    
                    Card1_button = new Button("Card1");
                    Card1_button.setForeground(Color.black);
                    Card1_button.setBackground(Color.lightGray);
                    this.add(Card1_button);
    
                    Card2_button = new Button("Card2");
                    Card2_button.setForeground(Color.black);
                    Card2_button.setBackground(Color.lightGray);
                    this.add(Card2_button);
    
                    Bet_button = new Button("Bet");
                    Bet_button.setForeground(Color.black);
                    Bet_button.setBackground(Color.lightGray);
                    this.add(Bet_button);
    
                    Check_button = new Button("Check");
                    Check_button.setForeground(Color.black);
                    Check_button.setBackground(Color.lightGray);
                    this.add(Check_button);
    
                    Fold_button = new Button("Fold");
                    Fold_button.setForeground(Color.black);
                    Fold_button.setBackground(Color.lightGray);
                    this.add(Fold_button);
    
    	   Bets = new Choice();
    	   Bets.addItem("5");
    	   this.add(new Label("Bet: "));
    } // end init()

    Whats the first part of your Class file. Something like..


    class myClass extends something implements somethingElse

    originally "extends Applet" but then changed it to "extends Applet implements ActionListener"

    You have a method called actionPerformed(ActionEvent e) set up in your class as well?
