话题：关于GroupLayout布局管理器的组件不完全显示的问题
最近在设计一个围棋的界面框架，分成了几个轻量级的jpanel类（QiPang，Player，PlayerPane，Chatroom）和一个主框架GameFrame类，但是一组合起来左边的QiPang的界面却不能完全显示，只显示了一部分，布局管理器是使用了GroupLayout，想了很久，还是不知道问题的所在，由于本人才刚接触布局管理器，不是很清楚，也有可能是其它一些常识的问题，请高手指点指点。贴出下面的源码，粘贴在eclipse上直接运行就行，代码是多了点，但已经删除了很多了。

[解决办法]
今天回答的最后一个问题。。回答完睡觉。
却不能完全显示，
恕我愚钝。没懂这句话的意思
这句话很关键，是一点都不显示，还是显示一部分呢？
我感觉不显示就两种可能。
一种是被别的组件给阻挡了。。所以不显示。
第二种就是你给设置成了不可见的模式。
