问题描述
本人比较菜，按书上的象棋打谱系统的源码进行了一些个性化的修改，但是发现一个非常严重的问题，在ChessBord类里面定义paintcomponent函数的时候如果使用g.drawImage然后保存，整个类里面的部分信息丢失，用g.fillRect却完全不会，我很费解，希望有能力的同学帮我看看现在贴出重点的类和函数ChinaChess类里面主要是点击了saveMenul按钮对board对象进行保存，代码如下

解决方案
解决方案二：
第二个为ChessBoard类，主要调用paintComponent函数，类代码如下

解决方案三：
最后是打开board对象的函数
publicvoidshowBoardManul(){stepNumber=1;stackStep.clear();stackBack.clear();if(demoOne!=null)remove(demoOne);try{FileInputStreamfile_in=newFileInputStream(file);ObjectInputStreamobject_in=newObjectInputStream(file_in);demoOne=(ChessBoard)object_in.readObject();file_in.close();object_in.close();ChessPiece[]redPiece=demoOne.getRedPiece();ChessPiece[]blackPiece=demoOne.getBlackPiece();for(inti=0;i<redPiece.length;i++){MouseListener[]listener=redPiece[i].getMouseListeners();for(intk=0;k<listener.length;k++)redPiece[i].removeMouseListener(listener[k]);listener=blackPiece[i].getMouseListeners();for(intk=0;k<listener.length;k++)blackPiece[i].removeMouseListener(listener[k]);MouseMotionListener[]mr=redPiece[i].getMouseMotionListeners();for(intk=0;k<mr.length;k++)redPiece[i].removeMouseMotionListener(mr[k]);mr=blackPiece[i].getMouseMotionListeners();for(intk=0;k<mr.length;k++)blackPiece[i].removeMouseMotionListener(mr[k]);}step=demoOne.getStep();for(inti=step.size()-1;i>=0;i--){stackStep.push(step.get(i));}demoOne.remove(demoOne.cancel);restoreChessBoard(step);split.setRightComponent(newJScrollPane(demoOne));}catch(Exceptionexp){add(newJButton("不是棋谱文件"),BorderLayout.CENTER);}}
