Question

我在XAML中定义了一个名为＆＃34; MyRectangle＆＃34;的矩形。点击后我执行以下代码：

    auto animation = ref new Windows::UI::Xaml::Media::Animation::DoubleAnimation();
    animation->From = 0.01;
    animation->To = 5.50;
    animation->AutoReverse = true;
    auto beginTime = Windows::Foundation::TimeSpan();
    beginTime.Duration = 0;
    animation->BeginTime = beginTime;
    auto duration = Windows::Foundation::TimeSpan();
    duration.Duration = 20000*1000;
    animation->Duration = duration;
    auto storyboard = ref new Windows::UI::Xaml::Media::Animation::Storyboard();
    auto scaleTransform = ref new Windows::UI::Xaml::Media::ScaleTransform();
    MyRectangle->RenderTransform = scaleTransform;
    storyboard->SetTargetProperty(animation, "(Rectangle.RenderTransform).(ScaleTransform.ScaleX)");
    storyboard->SetTarget(animation, MyRectangle);
    storyboard->SetTargetName(animation, "MyRectangle");
    storyboard->SpeedRatio = 1.0;
    storyboard->Begin();

然而，没有任何反应。我做错了什么？

你必须添加＆＃34;动画＆＃34; （或更多动画）到＆＃34;故事板＆＃34;儿童：

storyboard-＆GT; CHILDREN-＆GT;追加（动画）;

这是C＃等价物：

如何从C ++ \ CX创建XAML故事板动画？
