Java 怎样用mouseMoved（）实现鼠标移动触发事件

import javaawteventMouseEvent;
import javaawteventMouseMotionListener;
import javaxswingJButton;
import javaxswingJFrame;
public class BuTest implements MouseMotionListener{
JFrame jf=new JFrame("在按钮上移动的文字");
JButton[] button=new JButton[9];
int mount=0;
public void init(){
jfsetLayout(null);
jfsetSize(650, 100);
jfsetResizable(false);
jfsetLocationRelativeTo(null);
jfsetDefaultCloseOperation(JFrameEXIT_ON_CLOSE);
initButton();
}

public void initButton(){
int x=10,y=10;
for(int i=0;i<buttonlength;i++){
button[i]=new JButton();
button[mount]setText("点我");
button[i]setBounds(x, y, 60, 30);
jfadd(button[i]);
button[i]addMouseMotionListener(this);
x+=70;
}
jfsetVisible(true);
}

public static void main(String arg[]) {
new BuTest()init();
}
public void mouseDragged(MouseEvent e) {
}
public void mouseMoved(MouseEvent e) {
if(egetSource()==button[mount]){
button[mount]setText("");
if(mount!=8){
mount++;
}else{
mount=0;
}
button[mount]setText("点我");
}
}
}

其实就是鼠标事件就可以了。在执行鼠标事件的方法中判断即可
youbuttonaddMouseListener(new MouseAdapter(){
public void mousePressed(MouseEvent me){
//do something here
if( egetModifiersEx() == ( eBUTTON1_DOWN_MASK | eBUTTON3_DOWN_MASK) ){
Systemoutprintln("Both");
//这里是都按下的执行
}
}
});

package comossnmsethercliente2eservicecommonpanel;
import javaawteventMouseEvent;
import javaawteventMouseListener;
import javaxswingJFrame;
import javaxswingJLabel;
public class Tt extends JFrame implements MouseListener{
/
  @param args
 /
public static void main(String[] args) {
}
/
  为JLabel添加鼠标监听
  @param labels
 /
public void addMouseListener(JLabellabels) {
for(JLabel label:labels){
labeladdMouseListener(this);
}
}

public void mouseClicked(MouseEvent e) {
}
public void mousePressed(MouseEvent e) {
}
public void mouseReleased(MouseEvent e) {
}
public void mouseEntered(MouseEvent e) {
}
public void mouseExited(MouseEvent e) {
}
}

写这么个添加监听的方法，将生成的JLabel传进去不就行了
