使用模板控制自定义按钮的文本格式、换行符和颜色
Controlling text formatting, linebreaks, and colors of custom button with template
有人要求我构建一个相对简单的应用程序启动器程序（以替换旧的基于 DOS 的菜单系统）。我在 WPF 中构建了应用程序，并创建了一个自定义的 class 派生自名为“ApplicationLauncherButton”的按钮。
我希望所有按钮都具有相同的“外观和感觉”，因此我决定它们的样式都相同。因此，我决定用我要创建的模板替换控件模板。为了让我的主要 window XAML 尽可能干净，我创建了一个单独的资源字典文件来保存模板并在 app.xaml.
中引用它
这相当有效。但是，按钮上的某些文本很长，我想控制换行符出现的位置。通过将按钮文本包装在 TextBlock 中并在我需要的位置插入标签，可以相对轻松地完成此操作。不幸的是，这有一个副作用：不再应用我希望在鼠标悬停事件上发生的文本颜色更改。当按钮文本未包含在 TextBlock 中时，鼠标悬停格式会按预期工作，但我无法控制换行符出现的位置。
我花了几个小时试图弄清楚如何让它工作，但没有任何运气。我只使用 WPF 几个星期，所以可能有更简单的方法来完成我想做的事情。欢迎任何建议。

不得将纯文本和 Inline 元素混合作为 TextBlock 的内容。
使用 Run 显示文本。然后将 Run.Foreground 属性 绑定到 Button（或父 TextBlock）。请参阅下面的示例。
你的按钮模板也是错误的。您不应将 ContentPresenter 包装到 TextBlock 中，尤其是当您添加另一个 TexBlock 作为 Button.Content 的值时。这会给你一个 TextBlock 嵌套到 TextBlock:
<TextBlock> x:Name="TextBlockFromTemplate">
<TextBlock x:Name="TextBlockToReplaceContentPresenter" />
</TextBlock>
还将 ContentPresenter.HorizontalAlignment 绑定到模板化父项的 HorizontalContentAlignment（ContentPresenter.VerticalAlignment 也是如此）。不要明确设置它，因为这会断开 Button.HorizontalContentAlignment 与模板的连接，使其无用。
您可以使用针对 Run 的 Style，并将其添加到 ApplicationLauncherButton 的 Style 的 ResourceDictionary 中，以避免重复代码：
Generic.xaml
<Style TargetType="{x:Type local:ApplicationLauncherButton}">
<Style.Resources>
<Style TargetType="Run">
