将嵌套的HasTraits属性添加到TraitsUI TView

问题描述

我有一个 main HasTraits类，其中包含其他多个HasTraits对象的实例.我想在main对象的视图中定义一个Item，该对象指向嵌套对象的特征.例如:

i have a main HasTraits class which contains several Instance's of other HasTraits objects. I would like to define an Item in the view of the main object which points to a trait of a nested object. for example:

class Person(HasTraits):
    name = String()

class Pet(HasTraits):
    name = String()


class Family(HasTraits):
    father = Instance(Person,())
    dog = Instance(Pet,())

    view = View(
        Item('father.name'),
        Item('dog.name'),
        )

这可能吗?

谢谢！

推荐答案

一个叫Alex的人在1周前通过电子邮件问了这个问题，我们回复了:

Somebody named Alex asked this question 1 week ago by email, and we responded:

view = View(
    Item('object.father.name'),
    Item('object.dog.name'),
    )
