[]去掉了标题栏后仍然能够拖动窗口_J2SE

[求助]去掉了标题栏后仍然能够拖动窗口
我自己做了一个小程序,为了更加的美观,我把标题栏去掉了,我使用的是JFrame,在Jpanel上安放的JButton部件,同时我在一个类里面建立了三个方法,一个是构造方法,另一个是事件监听public void actionPerformed(ActionEvent e)方法,还有一个是main()方法,现在希望通过接口来实现拖动JTextField的时候能够拖动整个程序框体移动.求实现方法,谢谢.

------解决方案--------------------
addMouseMotionListener 监听鼠标拖动，在拖动时移动frame的位置
------解决方案--------------------

Java code

package net.csdn.www;import java.awt.Point;import java.awt.event.MouseEvent;import javax.swing.JFrame;import javax.swing.event.MouseInputAdapter;public class RemoveTitle {    public static void main(String[] args) {        new NoTitleWindow();    }}class NoTitleWindow extends JFrame {    public NoTitleWindow() {        setUndecorated(true);        setBounds(100, 100, 100, 100);        setVisible(true);        MouseOperate mo = new MouseOperate();        addMouseListener(mo);        addMouseMotionListener(mo);    }        private class MouseOperate extends MouseInputAdapter {        private Point point1;        public void mousePressed(MouseEvent e) {            point1 = e.getPoint();        }        public void mouseDragged(MouseEvent e) {            Point point2 = new Point();            point2 = e.getPoint();            int dx = point2.x - point1.x;            int dy = point2.y - point1.y;            int x = getX();            int y = getY();            setLocation(x+dx,y+dy);        }    }}
