源代码：
1.创建窗体的代码：
package lottery;
import java.awt.Color;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JTextArea;
public class LotteryFrame {
public static void main(String[] args) {
JFrame frame=new JFrame();
frame.setSize(868, 552);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setUndecorated(true);
frame.setLayout(null);
Lotterypanel panel=new Lotterypanel();
panel.setBounds(0, 0, 868, 552);
frame.add(panel);
frame.setVisible(true);
panel.addMouseListener(panel);
}
}
package lottery;
import java.awt.Color;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JTextArea;
public class LotteryFrame {
public static void main(String[] args) {
JFrame frame=new JFrame();
frame.setSize(868, 552);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setUndecorated(true);
frame.setLayout(null);
Lotterypanel panel=new Lotterypanel();
panel.setBounds(0, 0, 868, 552);
frame.add(panel);
frame.setVisible(true);
panel.addMouseListener(panel);
}
}
