Java – Swing中的mouseMoved（）事件处理
我想听听JFrame中的鼠标移动和点击。 为此，我添加了一个像这样实现的MouseListener 🙁 View类的完整代码位于https://gist.github.com/2837224，Board类位于https://gist.github.com/2837231 ）
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 && 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() + "."); } } 有趣的是，mousePressed（）运行良好，但其他两个都没有（移动鼠标时控制台上没有显示）。 谁能告诉我我做错了什么？ 提前致谢！
如果要接收mouseMoved和mouseDragged事件，还需要将侦听器注册为MouseMotionListener 。
MouseAdapter adapter = ... JFrame frame = ... frame.addMouseListener(adapter); frame.addMouseMotionListener(adapter);
也许您应该尝试实现MouseMotionListener和MouseListener ？
