title: Java - mouseMoved() event handling in Swing
body: <p>I want to listen for mouse movements and clicks in my JFrame. To do this, I've added a MouseListener implemented like this: (whole code of View class is at <a href="https://gist.github.com/2837224" rel="noreferrer">https://gist.github.com/2837224</a>, Board class is at <a href="https://gist.github.com/2837231" rel="noreferrer">https://gist.github.com/2837231</a>)</p>
  
  <pre><code>class BattleshipsFrame extends JFrame {
    private final Board playerBoard, opponentBoard;
    private View view;
  
  /** Main window constructor. */
  BattleshipsFrame() {
    ...
    ...   
    ...
    //creating and displaying boards
    playerBoard = new Board();
    opponentBoard = new Board();
    PlayerBoardListener mouseListener = new PlayerBoardListener();
    this.addMouseListener(mouseListener);
    playerBoard.addMouseListener(mouseListener);
    opponentBoard.addMouseListener(new OpponentBoardListener());
    boards.add(playerBoard);
    boards.add(opponentBoard);
    ...
    ...
    ...
  }
  
  /** Listener responsible for handling mouse events on player board */
  private class PlayerBoardListener extends MouseAdapter {
    @Override public void mousePressed(MouseEvent event) {
      try {
        if(event.getButton() == MouseEvent.BUTTON1 &amp;&amp; controllerConnection != null)
          controllerConnection.sendShipPlacedEvent(event.getX()/40, event.getY()/40, ShipType.EMPTY);
      } catch(Exception e) {
        e.printStackTrace();
      }
    }   
    @Override public void mouseMoved(MouseEvent event) {
      //TODO
      System.out.println("Mouse movement detected! Actual mouse position is: " + event.getX()+ "," + event.getY() + ".");
    }   
    @Override public void mouseDragged(MouseEvent event) {
      //TODO
      System.out.println("Mouse movement detected! Actual mouse position is: " + event.getX()+ "," + event.getY() + ".");
    }   
  
  }
  </code></pre>
  
  <p>Funny thing is that mousePressed() is working well, but the other two are not (nothing shows on console while moving the mouse). Anybody could tell me what am I doing wrong? Thanks in advance!</p>
