如何将窗体窗口的所有者设置为 WPF Window？

Question

My application is built in WPF .NET Framework.

I have an WPF MainWindow and I want to make several FormWindows as children of the WPF MainWindow. When making child WPF Window of parent WPF Window, I can simply put Owner = this to child window but it does not work on Form Window, of course.

is there any way to make it possible?

thanks in advance

No, you cannot set the Owner property of a WPF window to anything else than another WPF window.

There is a WindowInteropHelper class that has an Owner property that can be set to the HWND of a form:

Form1 form = new Form1();
WindowInteropHelper wih = new WindowInteropHelper(wpfWindow);
wih.Owner = form.Handle;

Another suggestion would be to skip the forms and move the contents of the forms into WPF windows, for example using the WindowsFormsHost control.
