如果自定义 chrome 工具不能为您提供您想要的外观,这种事情很容易在 C# 中自己完成。基本上,您创建一个无边框表单 (FormBorderStyle = None),然后自己创建所有控件和边框,方法是将控件放置在您需要的位置(标题栏的标签、关闭和最小化的命令按钮等)和/或绘图使用 Graphics 对象直接在表单的表面上。
您还必须实现代码以允许通过其“假”标题栏拖动表单(有关如何执行此操作的示例,请参见此答案)。您可能还必须实现自己的调整大小机制(如果您需要调整表单大小)。
最后,虽然自定义表单代码可能有点笨拙,但您可以在单个表单上实现它,然后让应用程序中的所有其他表单继承此表单,这使其成为自定义整个皮肤的非常有用的技术应用。
我的任务是让活动窗口比其他应用程序的非活动窗口更引人注目、更明亮。应用程序有许多打开的窗口,一些模式,一些无模式 - 和 MDI 父窗口。
您可以使用非边框之类的东西 - 客户区域内的框架。这是代码片段,是基类的一部分(可以直接在表单中使用):

类的静态字段从应用程序设置表单(类)初始化 - 因此,应用程序中的所有表单具有相同的行为。
希望对某人有所帮助。
