我用插件 treeview6.0，怎么根据选项打开相应的画面.画面1、2、3、4、5，求大神指点.

Sub OnLButtonDown(Byval Item, Byval Flags, Byval x, Byval y)            

Dim MyObj,Node1,Node2,count

Set MyObj = ScreenItems("Tree") 

Set Node1 = MyObj.Nodes.Add(,,"Name","画面1")

Set Node1 = MyObj.Nodes.Add(,,"Name1","画面2")

Set Node1 = MyObj.Nodes.Add(,,"Name2","画面3")

Set Node2 = MyObj.Nodes.Add(,,"Age","画面4")

Set Node2 = MyObj.Nodes.Add(,,"Age","画面5")

End Sub
