java自定义窗口风格.docx

Java 自定义窗口风格大家有的时候是不是会觉得java默认的窗口风格，很单一、古板，不好看，希望自己搞些漂亮的风格（如qq登陆界面）。看下面两张图：Java 默认的窗口风格：本程序实现的风格：很多时候，我们是需要下面的风格的，而java又不提供现成的方法，这就要我们自己去写代码实现。要想自己定义java窗口的风格，首先应取消java自带的默认风格，用JFrame里的setUndecorated(true);方法可以取消默认风格，然后自己重画最大、最小、关闭按钮，需要注意的是，取消默认风格后，要想再移动窗口，需要自己再编写类来处理事件，下面粘贴完整的代码，给那些想自定义窗口风格的童鞋以帮助，希望高手勿喷。1主程序：package MyPanel;import javax.swing.*;public class MyFrame extends JFrame public MyFrame() this.setUndecorated(true);this.setBounds(300, 200, 348, 265)；;init();this.validate();public void init() this.setTitle(自定义窗口风格);MyPanel pane = new MyPanel(MyPanel.CLOSE_MIN_MAX, picture/picture.jpg);pane.setFrame(this);MyListener moveListener = new MyListener(this);this.addMouseListener(moveListener);this.addMouseMotionListener(moveListener);this.setContentPane(pane);this.setVisible(true);public static void main(String args) new MyFrame();2事件处理类：package MyPanel;import java.awt.Point;import java.awt.Rectangle;import java.awt.event.MouseAdapter;import java.awt.event.MouseEvent;public class MyListener extends MouseAdapter private Point lastPoint = null;private MyFrame window = null;public MyListener(MyFrame window) this.window = window;public void mousePressed(MouseEvent e) lastPoint = e.getLocationOnScreen();public void mouseDragged(MouseEvent me) Point point = me.getLocationOnScreen();int offsetX = point.x -
