我创建了一个WFP UserControl，其中包含一些复杂的XAML（从SVG转换而来）。它基本上是一个花哨的按钮。
我想在usercontrol的XAML中创建一个动画，将它的位置向右和向下“移动”4个像素，以模拟点击，然后让它弹回原来的位置。
对我而言，这听起来像任何人都会在WPF中学到的第一部动画，但我找不到一个好的例子。
如果有人有兴趣，我已加入UserControl。

答案 0 :(得分：0)
请参阅UIElement.RenderTransform。对于类似按钮的控件，执行此操作的典型方法是为按钮设置属性，例如IsPressed，您的控件在true中设置为OnMouseDown，然后返回到false的{{1}}。然后在OnMouseUp上设置一个带触发器的样式，它会将IsPressed == true设置为导致移位 - 这大致是普通WPF RenderTransform执行此操作的方式。
在您的情况下，如果您的控件具有与普通Button完全相同的行为，只有不同的外观，我实际上不会使用Button - 我只是为{创建自定义样式{1}}，使用自定义模板，并使用它（并使用UserControl）。
