C# WPF DragMove 不带 Window_LocationChanged()
我在 Windows 窗体中实现了类似于 DragMove 的功能，但边界设置为主屏幕边距的 10 个单位。
当切换到 WPF 时，我发现此线程对于实现相同的结果很有用。
但是，由于这是一个移动后事件，因此如果我的窗口被拖动到我设置的边界之外，它就会“跳”回来。我想避免这种效果，因为它看起来很糟糕。
有没有一种简单的方法可以避免窗口在不使用 LocationChanged 事件的情况下移动到给定区域之外？我基本上想在发生之前限制窗口的移动。
I implemented something in Windows Forms similar to DragMove but with boundaries set to 10 units of the margins of the primary screen.
When switching over to WPF I found this thread to be useful in achieving the same result.
However, since this is a post-move event, what happens is that if my window is dragged beyond the boundaries I set, it "jumps" back. I would like to avoid this effect as it looks terrible.
Is there a simple way to avoid the window to be moved outside a given area without using the LocationChanged event? I basically want to restrict the movement of the window before it happens.

这些使用 WPF 很难实现，因为它不像 WinForms 那样公开基本的 Win32 函数和事件。我有一个项目需要调整窗口大小，并且必须使用 PInvoke SetWindowPos 以正常方式执行此操作。
AddHook 可能会帮助你，但这仍然会很困难。请参阅 http://www. wpfmentor.com/2009/01/how-to-get-hwnd-and-hook-into-wndproc.html 和 http://msdn.microsoft.com/en-us/library/system.windows.interop.hwndsource.addhook.aspx了解更多信息。
These this are very hard to achieve with WPF because it does not expose the base Win32 functions and events like WinForms did. I had a project where I needed to to resize a window and I had to use PInvoke SetWindowPos to do this in a normal manner.
AddHook may help you, but this will still be quite difficult. See http://www.wpfmentor.com/2009/01/how-to-get-hwnd-and-hook-into-wndproc.html and http://msdn.microsoft.com/en-us/library/system.windows.interop.hwndsource.addhook.aspx for more information.
