如在运行时取得一个自定义对象实例是继承于哪一个用户自定义类

[wallis]

定义了用户对象uo_abc
在窗口上建立了一个该对像的实例uo_1,请问如何得到该对象继承于哪个用户对象
例如：
如何在运行时得到uo_1继承预uo_abc

是classname()?
还是typeof() ?
忘了，试试吧。

[wallis]

不要用typeof(),它只能得到userobject!,而我要得到的是uo_abc

[wallis]

classname()得到的是uo_1

那你就用这个吧。不过我没用过。
ClassDefinition object

The ClassDefinition object lets you check:

1。The name of the class
2。The library the class was loaded from
3。The class definition of its ancestor, if any
4。The class definition of its parent or container object, if any
5。Whether the class is autoinstantiated
6。Whether the class is a system class (defined by PowerBuilder) or a user-defined object (defined in a PowerBuilder PBL)
7。The classes the object contains, such as the controls contained in a window

8。The variables and scripts defined in the class

可能要这样：
ClassDefinition lcls_par,lcls_this
string ls_parName
lcls_this = uo_1.classdefinition
lcls_par = lcls_this.Ancestor

ls_parName = lcls_par.name
你试试看。
