.net - 如何在 Linux 上更改 WinForms 应用程序的 WM_CLASS？

Question

我有一个使用 WinForms 的跨平台 .NET 应用程序。

为了更好地与 Unity 兼容，我想设置 WM_CLASS WinForms 窗口的属性。这可能吗？

在这里似乎有完整的示例项目 bitbucket.org/hindlemail/settingwmclass :

Example project showing how to set the WM_CLASS X11 property for a mono winform application running on Linux. This makes mono winforms applications behave better with the unity + gnome3 window managers.

    // Managed struct of XSetClassHint classHint.
    public struct XClassHint
    {
        public IntPtr res_name; 
        public IntPtr res_class;
    }       


    [DllImport ("libX11", EntryPoint="XSetClassHint", CharSet=CharSet.Ansi)]
    public extern static int XSetClassHint(IntPtr display, IntPtr window, IntPtr classHint);


    public static void SetWmClass(string name, string @class, IntPtr handle)
    {           
        var a = new NativeX11Methods.XClassHint { 
                        res_name = Marshal.StringToCoTaskMemAnsi(name), 
                        res_class = Marshal.StringToCoTaskMemAnsi(@class) 
                    };
        IntPtr classHints = Marshal.AllocCoTaskMem(Marshal.SizeOf(a));
        Marshal.StructureToPtr(a, classHints, true);
          NativeX11Methods.XSetClassHint(NativeReplacements.MonoGetDisplayHandle(),     NativeReplacements.MonoGetX11Window(handle), classHints);           

        Marshal.FreeCoTaskMem(a.res_name);
        Marshal.FreeCoTaskMem(a.res_class);

        Marshal.FreeCoTaskMem(classHints);
    }
