闲着没事,网上找了许多资料自学JAVA不久,想尝试自己做个什么项目.但是碰到个小小的困难,就是面板布局的时候,其中的表单超过了显示的范围,想在其中加JScrollPane的滚条效果.我显示用GridBagConstraints()布局,但是表单的位置设置不好(是水平不佳吧..)..后来用setBounds(X,X,X,X)定义表单位置,却没有了滚条的效果.又找不到解决的方法.想寻求下帮助,谢谢!(另外..有个较笨的错误,首页上有个txt表单,不知怎么去掉..知道是哪写错了漏了帮个忙,谢谢~THANKS!)
代码如下:

不是不般的长啊~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
----------------解决方案--------------------------------------------------------
还没打算写功能呢...
----------------解决方案--------------------------------------------------------
刚学的时候都很想自己写程序来测试自己学得怎么样了，这无可厚非，但首先你要多看看别人是怎么写程序的……我想对你的程序提一点意见……觉得有用的就记一下，觉得没用就当我放P吧……
1. 程序过长是显而易见的……为什么会造成的呢？因为过多的重复代码引起的……你肯定会想反驳我吧？这里面没一句是重复的！JPanel申明了lbseao1~lbseao18，你完全可以使用数组来做，其他的组件也一样.你的第三部分看看基本上就被setVisible覆盖了，如果使用数组的话可以使用一个方法或一个循环就可以解决一大段了
2. 按钮“系统设置”、“基本信息”等等，这些完全可以使用菜单栏来代替，根本不必写一大堆的setVisible
对于你的问题暂时还不知道是怎么回事……
