WPF：动画自定义依赖属性？

问题描述

让我们说，我定义这样的依赖性：

Let's say that I've defined a dependency like this:

     public class MySampleClass
    {public static DependencyProperty MyDoubleProperty = DependencyProperty.Register("MyDouble", typeof(double), typeof(MySampleClass));
    public double MyDouble
    {
        get
        {
            return (double)GetValue(MyDoubleProperty);
        }
        set
        {
            SetValue(MyDoubleProperty, value);
        }
    }
}

我想一个DoubleAnimation是适用于该值。我怎样才能做到这一点？始终之前，我已经通过调用UIElement的BeginAnimation方法使用DoubleAnimations。

I'd like to apply a DoubleAnimation to this value. How can I do this? Always before, I've used DoubleAnimations by calling the BeginAnimation method of a UIElement.

感谢您的帮助！

推荐答案

您尝试使用DoubleAnimation是在不自UIElement继承一个类？如果不是这样，你至少应该自Animatable继承，或其他一些基类，它也支持BeginAnimation。

Are you trying to use a DoubleAnimation on a class that doesn't inherit from UIElement? If not, you should at least inherit from Animatable, or some other base class which also supports BeginAnimation.
