如何重新渲染UI以响应隐藏在嵌套类中的计算属性？

# 嵌套类
class NestedClass:
    def __init__(self):
        self._value1 = 0
        self._value2 = 0
    
    @property
    def value1(self):
        return self._value1
    
    @value1.setter
    def value1(self, new_value):
        self._value1 = new_value
    
    @property
    def value2(self):
        return self._value2
    
    @value2.setter
    def value2(self, new_value):
        self._value2 = new_value

# UI组件
class UIComponent:
    def __init__(self, nested_class):
        self.nested_class = nested_class
    
    def render(self):
        # 获取计算属性的值
        computed_value = self.nested_class.value1 + self.nested_class.value2
        
        # 渲染UI
        print(f"Computed value: {computed_value}")

# 创建嵌套类对象和UI组件对象
nested_obj = NestedClass()
ui_component = UIComponent(nested_obj)

# 第一次渲染UI
ui_component.render()

# 更新计算属性的值
nested_obj.value1 = 5
nested_obj.value2 = 10

# 第二次渲染UI
ui_component.render()
