鼠标事件MouseEvent可以给控件/界面添加鼠标事件有三种监听器：1.addMouseListener 点击，按住，抬起，移入，移出2.addMouseMotionListener 移动，拖动3.addMouseWheelListener 鼠标滚轮转动MouseListener接口下要覆盖五个方法：mouseClicked，mouseEntered，mouseExited，mousePressed，mouseReleased分别对应不同的鼠标事件。对于鼠标事件MouseEvent的常用方法：getX()/getY 获取当前点击位置的坐标（相对于界面）getXOnScreen()/getYOnSreen() 获取当前点击位置的坐标（相对于屏幕）getSource() 点击的控件getButton() 左键/中建/右键getClickCount() 单机/双击/三击由于每次使用MouseListener接口都要重写五个方法，所以改用抽象类MouseAdapter，要用哪个就写哪个。
以mouseClicked为例代码：
root.addMouseListener(new MouseAdapter(){
@Override
public void mouseClicked(MouseEvent e){
if(e.getButton() == MouseEvent.BUTTON1) System.out.println("左键");
else if(e.getButton() == MouseEvent.BUTTON2) System.out.println("中键");
else if(e.getButton() == MouseEvent.BUTTON3) System.out.println("右键");
int cc = e.getClickCount();
if(cc == 1) System.out.println("单机");
else if(cc == 2) System.out.println("双击");
System.out.println("鼠标位置:" + e.getX() + "," + e.getY());
System.out.println("------------");
}
});
MouseWheelListener滚轮事件
例：
MouseWheelListener wheelListener = new MouseWheelListener(){
@Override
public void mouseWheelMoved(MouseWheelEvent e){
Image image = canvas.getImage();
int i;
for(i=0;i if(buttons.get(i).getImage()==image) break; } ThumbButton button = buttons.get(i); if(e.getUnitsToScroll()>0){ //滚轮向下时e.getUnitsToScroll()大于0 button = nextImage(i); }else{ //滚轮向上时e.getUnitsToScroll()小于0 button = lastImage(i); } setBlueBorder(button); } }; ————————————————版权声明：本文为CSDN博主「Cobb141」的原创文章，遵循CC 4.0 BY-SA版权协议，转载请附上原文出处链接及本声明。原文链接：https://blog.csdn.net/Cobb141/article/details/108967016
