java小程序中鼠标事件的响应处理

　　


                  如何在小程序中实现鼠标响应？

public class Hello extends Applet implements MouseListener{



public void init(){

addMouseListener(this);

}

public void mouseEntered(MouseEvent e){

au.play();

setBackground(Color.blue);

}



public void mouseExited(MouseEvent e){

setBackground(Color.black);

}



public void mousePressed(MouseEvent e){}



public void mouseReleased(MouseEvent e){}



public void mouseClicked(MouseEvent e){}



}

首先在小程序中实现事件监听器，再实现鼠标用户接口





如何小程序中处理鼠标双、三击？



component.addMouseListener(

new MyMouseListener());



public class MyMouseListener extends MouseAdapter {

public void mouseClicked(MouseEvent evt) {

if (evt.getClickCount() == 3) {

// 处理鼠标三击

} else if (evt.getClickCount() == 2) {

// 处理鼠标双击

}

}

}



处理鼠标右键



public mouseClicked(MouseEvent e){



if(e.isMetaDown()){//检测鼠标右键单击



}



如何在小程序中处理鼠标中间键？



new MyMouseListener());



public class MyMouseListener extends MouseAdapter {

public void mouseClicked(MouseEvent evt) {

if ((evt.getModifiers() &?

InputEvent.BUTTON1_MASK) != 0) {

processLeft(evt.getPoint());

//处理鼠标左键单击

}

if ((evt.getModifiers() &?

InputEvent.BUTTON2_MASK) != 0) {

processMiddle(evt.getPoint());

//处理鼠标中间键单击

}

if ((evt.getModifiers() &?

InputEvent.BUTTON3_MASK) != 0) {

processRight(evt.getPoint());

//处理鼠标右键单击

}

}

}
