描述

　　Form2,Form3,Form4都是独立存在的,同时完成独立的功能,相互不依赖。

最后把Form2,Form3,Form4集合放在FORM1上,实际上需要这3个的窗体Form2,Form3,Form4间相互得到改变后的变量值。

FORM2 文件夹列表

在FORM1中设置一初始文件夹路径　　

　　要实现的功能：当单击本窗体中的TreeView.node时，要求Form3.ListView的文件列表同时更新。

FORM3 文件列表

　　需要得到Form2当前选中的文件夹路径

要实现的功能：当本窗体中的ListView选中一个节点时时，同时Form4.RichtextBox 打开并读取这个文件。

FORM4是一个RFT编辑器

　　需要得到FORM3 文件列表中选中的文件完整路径

要实现的功能：当单击本窗体中的保存按钮，要保存Form3.ListView中选中的那个文件。

实现步骤

1 创建4个空窗体分别为：Form1.cs,Form2.cs,Form3.cs,Form4.cs

Form1:3个Panel

一个SpilterContain拖拽好结果正确的模型架可以保存SpilterContain的位置用的是XML

关于效果你可以自己用个splitContainer1 做3个面板去做个拖拽窗体时大小改变和WINDOWS的EXPLORER一样的结果为正确
