我是设计WPF前端的新手，请多多包涵。目前我正在为我的 XAML 应用程序创建一种样式，并且在某个时候需要帮助。我有 3 个 XAML 文件：1 个用于我的画笔绘画路径，1 个用于我的样式/颜色和 mainWindow.xaml。在我的风格中，我想创建一个自定义按钮，其中包含一个堆栈面板、一个网格和一个带有 opcityMask 填充的矩形，该填充在其上绘制了一个 visualBrush 路径。您介意帮助我了解如何访问和更改矩形填充的绘画路径吗？是否有可能附加依赖属性或其他可更改属性来更改Rectangle.OpacityMask -> VisualBrush -> 视觉路径直接来自我的 mainWindow.xaml？如何从另一个 xaml 文件的样式中访问这样的画笔绘画路径？有没有办法将新属性附加到 mainWindow.xaml 中可以设置使用的绘画路径的代码？或者您在使用样式时如何更改此类路径？非常感谢你们非常感谢您的帮助！如果某些事情没有 100% 准确地描述，请告诉我。
这是我的代码：
