TreeList控件的节点图标设置，在显示属性里要么设置为全部显示，要么全部不显示。

当前项目需求为，个别节点设置为不可用，个别节点设置为只显示线不显示选择框，由此只能抛弃treelist自身的checkbox显示设置，自己画图标。

利用StateImage属性设置图标显示，首先做一个图标的枚举，从资源文件里读取：

[csharp] view plain copy print?

1. /// <summary>  
2.     /// TreeList页节点选择状态  
3.     /// </summary>

7.         UnCheckedBranch = 1,//未选中枝

9.         UnCheckedLeaf = 3,  //未选中叶(暂不用，跟1一样)

11.         LeafLine = 5,       //叶线
