同时使用mouseClicked和mouseDragged

Question

我试图在java中同时使用mouseClicked和mouseDragged。但mouseClicked属于MouseListener，mouseDragged属于MouseMotionListener。任何帮助将不胜感激，谢谢。

Answer 1

为了方便起见，您可以查看MouseAdapter，其中MouseListener，MouseMotionListener和MouseWheelListener

MouseAdapter ma = new MouseAdapter() {
    public void mouseClicked(MosueEvent evt) {
        // Do what ever here
    }
    public void mouseDragged(MosueEvent evt) {
        // Do what ever here
    }
}

yourComponent.addMouseListener(ma);
yourComponent.addMouseMotionListener(ma);

有关详细信息，请参阅How to Write a Mouse Listener

同样，你可以创建自己的类......

public class MyAwesomeMouseHandler implements MouseListener, MouseMotionListener {
    // Implement the required methods...
}

然后你只需创建一个实例添加注册它们......

MyAwesomeMouseHandler handler = new MyAwesomeMouseHandler();

yourComponent.addMouseListener(handler);
yourComponent.addMouseMotionListener(handler);

你可以分别实现侦听器并分别注册它们......
