WinForms中具有浮动精度大小的WPF自定义控件

Question

我想知道是否可以在 wpf 中创建一个类似面板的控件，以及另一个 wpf 自定义控件将成为该面板的子控件，所有这些都在 WinForms 应用程序中。然后，是否可以将自定义控件的大小设置为浮动？ 我还可以旋转那个自定义控件吗？

提前致谢

您将需要使用 System.Windows.Forms.Integration 命名空间，更具体地说是 ElementHost Control，这将允许您在 Winforms 中嵌入 WPF 控件。

这是更改 WPF 用户控件子用户控件大小和位置的快速简单的演示。我把动画留给你。
