---------------------------------------------------------
WebFXTreeAbstractNode
父类对象有共同的函数和方法被WebFXTree和WebFXTreeItem两个子类对象继承;
参数
id Number 只读属性，节点的唯一ID
如果只读HTML元素的id就能得到JS对象然后放入webFXTreeHandler集合.
text String 节点的文本
action String 响应关联uri给节点
open Boolean 只读。返回节点是否打开 如果没有子节点一直返回false
icon String 节点图像,未指定时
openIcon String 节点打开时的图像，未指定时
parentNode Reference 关联父节点
childNodes Array 所有子节点
方法
add(oNode, [bNoIdent]) Reference 添加
indent() void 缩进
toggle() void 切换
expand() void 打开树节点
collapse() void 关闭树节点
expandAll() Void 打开所有节点
collapseAll() Void 关闭所有节点
getNextSibling() Reference 得到前一兄弟节点
getPreviousSibling() Reference 得到后一的兄弟节点
toString() String 返回HTML格式
--------------------------------------------------------
WebFXTree
构造方法:
new WebFXTree([text], [action], [behavior])
参数
text String 节点的文本
action String 响应关联uri给节点
behavior String 节点的行为
icon String 节点图像,未指定时
openIcon String 节点打开时的图像，未指定时
属性：
rendered 标志位，boolean类型，表明树是否已创建并渲染
方法
getSelected() Reference 得到被选中的对象
setBehavior(sBehavior) Void 默认为classic,如果设置为explore时可以使树节点展示看起来更像windows Explore
getBehavior() String 返回classic/explore
---------------------------------------
WebFXTreeItem
构造方法
new WebFXTreeItem([text], [action], [parent], [icon], [openIcon])
参数
text String 节点的文本
action String 响应关联uri给节点
parent Reference 父节点（可选参数）
icon String 节点图像,未指定时
openIcon String 节点打开时的图像，未指定时
方法
getFirst() Reference 返回一个子节点的引用
getLast() Reference 返回最后一个子节点的引用
实例
