【汇智学堂】-JAVA桌面游戏开发（五子棋之三：程序主界面）

之三：程序主界面

等级选择“初级”，进入“程序主界面”，效果见下图：

准备工作：

Images文件夹下，放置level.png图片一张。

代码实现：

PCBoard .java

package com.fivechess.view;

public class PCBoard extends Board {
private PCChessBoard2 pcchessboard2;//棋盘
public PCBoard() {
init();
}

public void init() {		
	pcchessboard2=new PCChessBoard2();		
	pcchessboard2.setBounds(200, 50, 600, 700);
	pcchessboard2.setVisible(true);		
	add(pcchessboard2);		
}

}

//Board类的代码：

package com.fivechess.view;
import java.awt.Graphics;
import javax.swing.JFrame;

public class Board extends JFrame {

public Board() {
	 
	 setLayout(null); //取消原来布局
     setBounds(300,50,800,700);
     //init1();
     setVisible(true);
        
     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     setResizable(false);
     
     setTitle("雷雷的五子棋");
}

/**
 * 绘图
 * @param g
 */
public void paint(Graphics g)
{
    super.paint(g);
    repaint();
}

}

//棋盘PCChessBoard2类

package com.fivechess.view;

import java.awt.event.MouseEvent;
import javax.swing.JOptionPane;

public class PCChessBoard2 extends ChessBoard2{

public int whichColor=0;
private int ex;
private int ey;	

public static int isClose=0;	
	
//落下棋子
