我有一个简单的益智游戏.有一个由16块瓷砖组成的图像(随机放置).图像存储在一个数组中,当游戏启动时,它们被添加到主JPanel中.

替代文字http://img248.imageshack.us/img248/7403/27632947.gif

游戏以这种方式工作:每个图像都有"地点"和"数字"."放置"是网格上的当前位置(正确与否),"数字"是图像的所需位置.当用户点击图像时,会检查其"地点"和"数字"属性.如果他们匹配什么都没发生 如果没有游戏检查当前是否有任何图像在内存中.如果没有,则存储该图像的"位置"和"数字".如果内存中有一些图像,则使用存储图像的"数字"检查当前单击的图像的"plac".当他们匹配时 - 他们的位置被交换.这部分工作正常.但是现在,我正在使用更新的图像在我的JPanel上调用addComponent方法,而且没有任何反应.不该"

这是 JFrame

package client.connection;

import java.awt.Dimension;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import javax.swing.JFrame;


class DrawFrameRemoteControl extends JFrame
{
    private DrawPanelRemoteControl imagePanel;
    private ClientRemoteControlConnection clientRemoteControlConnection;
    private ObjectInputStream clientInputStream;
    private ObjectOutputStream clientOutputStream;
    private Dimension imageDimension;
    private Dimension serverDimension;

    public DrawFrameRemoteControl(Dimension imageDimension,ClientRemoteControlConnection clientRemoteControlConnection,ObjectInputStream clientInputStream,ObjectOutputStream clientOutputStream,Dimension serverDimension)
    {
        super("Remote Desktop Control");

        this.clientRemoteControlConnection=clientRemoteControlConnection;
        this.clientInputStream=clientInputStream;
        this.clientOutputStream=clientOutputStream;
        this.imageDimension=imageDimension;
        this.serverDimension=serverDimension;

        imagePanel=new DrawPanelRemoteControl(imageDimension);
        add(imagePanel);


        setSize(imageDimension.width,imageDimension.height);
        setResizable(false);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setVisible(true);
        setLocationRelativeTo(null);
    }

    void drawNewImageGrayscale(byte[] array)
    {
        imagePanel.setNewImageGrayscale(array);
        imagePanel.repaint();
    }
}

这是扩展的JPanel类 -
