VBA中等效的树图

Question

我想知道在二进制文件旁边是否有VBA中的内置树图对象。

现在我正在使用4个嵌套字典（来自脚本DLL）， 每个人都在分开的班级中宣布。

Classe A
Private dicA As Dictionary
'can do stuff with dicA
'dicA contains String as Key and Class B object as Value

Classe B

Private dicB As Dictionary
'can do stuff with dicB
''dicB contains String as Key and Class C object as Value

Classe C

Private dicC As Dictionary
'can do stuff with dicB
''dicC contains String as Key and Class D object as Value

Classe D

Private dicD As Dictionary
'can do stuff with dicD
'dicD contains String as Key and String as Value

总之，Classe D对象是来自C类对象的子节点，C类对象是B类对象的子节点，等等......

我想知道是否有更好的方法在VBA中获得这种数据结构。

提前感谢。
