重用情节提要

Question

我正在自学如何使用 Blend some MS lessons。我正在经历的一个项目是一个计算器，其中计算器键是使用下面的 xaml 定义的，每个都有自己的故事板来动画按键的按下和释放。

每个键的图像都是在 Photoshop 或类似软件中创建的，最终结果是下面漂亮的计算器。

问题：

1. 是否可以定义 StoryBoard 一次并为每个“键”重复使用它？怎么样？
2. 是否可以将每个键变成一个按钮？怎么样？

下一步是学习如何template a button。之后，您可以使用“Pressed”和“Normal”状态之间的过渡效果。

例子：

您必须根据使用情况调整这些样式（图像而不是文本等）。 在经过这个 sn-p 之后的 Blend 中，右键单击一个按钮，Edit Template > Edit Current...

或在资源面板中：右键单击 CalcButtonStyle 编辑 您可以在此模式下更改默认属性（背景颜色、边距等）。如果您想更改模板：在对象和时间轴面板上，右键单击“ 样式”编辑模板> 编辑当前... 您可以在“状态”面板中看到不同的状态（正常、按下等）。

在您的情况下，模板可能如下所示：
