scroll_x

当改变时触发观察者的一种可观察的属性。

    def log_change(instance, value):
        print("Something changed")

    class MyObject:

:param default: Default value which is returned, if no value set before
:param default_factory: A callable which returns the default value.
                        Will be called with the property and the instance
