我想要一个在未选中状态下不可见的复选框。未选中时，将鼠标悬停在它上面会使其动画显示为0.3透明度。
当鼠标指针离开复选框并且仍未选中时，它会动画回到0透明度。
选中后，它将完全可见，即。透明度= 1。
到目前为止我的所有尝试都没有成功，我认为由于鼠标悬停规则。当我的复选框被选中时，鼠标悬停仍会导致淡入淡出为0.3，在鼠标离开时，它变得不可见。 我尝试使用触发器，多重触发器，VSM，但我无法弄清楚如何编写我想要的行为而不会发生冲突。
代码： 这是触发器方法。它已经经历了这么多次迭代，我甚至不记得这是否是我最初的方法。 我也有一个VSM方法，只要说你也想要那个代码。

好吧，我只是采取了一些恶魔般的解决方法。鼠标悬停的东西与虚拟背景路径/图像一起工作，而检查＆amp;取消选中使用主路径/图像。

检查触发器的位置：将IsChecked触发器置于IsMouseOver触发器下。
