在PyQt中处理双向绑定的更好方法？

from PyQt5.QtCore import QObject, pyqtSignal, pyqtSlot

class DataModel(QObject):
    valueChanged = pyqtSignal(int)

    def __init__(self):
        super().__init__()
        self._value = 0

    @property
    def value(self):
        return self._value

    @value.setter
    def value(self, new_value):
        if self._value != new_value:
            self._value = new_value
            self.valueChanged.emit(new_value)

class UI(QObject):
    def __init__(self, data_model):
        super().__init__()
        self.data_model = data_model
        self.data_model.valueChanged.connect(self.update_value)

    @pyqtSlot(int)
    def update_value(self, new_value):
        print(f"New value: {new_value}")

    def set_value(self, new_value):
        self.data_model.value = new_value

data_model = DataModel()
ui = UI(data_model)
ui.set_value(10)  # 输出：New value: 10
