中有没有办法可以删除主窗口的边框,但允许调整窗口大小(没有夹点)?
我意识到有一种方法可以通过将调整大小模式设置为CanResizeWithGrip来完成此方案.但是,我希望能够将调整大小模式设置为CanResize.
我尝试设置以下内容:
ResizeMode="CanResize" WindowStyle="None" AllowsTransparency="True"
但是,通过设置allowsTransparency,它将删除没有夹点时调整大小的功能.我有什么想法可以解决这个问题吗?
我还应该注意,无论如何我都不能将AllowTransparency设置为true,因为我在我的窗口中使用了winformshost控件,当AllowTransparency为true时,它不显示.
我知道这是一个老问题,但我只想为新人提出一个工作样本.
