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
@Override
public void mouseMoved(MouseEvent e) {		
	repaint();		    	
} 

@Override
public void mouseClicked(MouseEvent e) {
	
	if(isClose==1) {
		return;
	}
	
	 ex=e.getX();
	 ey=e.getY();
	 
	 float x = (ex - 25) / 25;
     float y = (ey - 25) / 25;
     int x1 = (int) x;
     int y1 = (int) y;		
}
