WPF最小化任务栏单击

Question

我有一个WPF应用程序,按利益相关者的要求必须有一个WindowStyle ="None",ResizeMode ="NoResize"和AllowTransparency ="True".我知道,通过不使用Windows chrome,您必须重新实现许多操作系统窗口处理功能.我能够创建一个可用的自定义最小化按钮,但是当您单击屏幕底部的任务栏图标时,我无法重新实现Windows最小化应用程序的功能.

用户要求是应用程序应最小化任务栏图标单击并在再次单击时恢复.后者从未停止过工作,但我无法实施前者.这是我正在使用的代码:

    public ShellView(ShellViewModel viewModel)
    {
        InitializeComponent();

        // Set the ViewModel as this View's data context.
        this.DataContext = viewModel;

        this.Loaded += new RoutedEventHandler(ShellView_Loaded);
    }

    private void ShellView_Loaded(object sender, RoutedEventArgs e)
    {
        var m_hWnd = new WindowInteropHelper(this).Handle;
        HwndSource.FromHwnd(m_hWnd).AddHook(WindowProc);
    }

    private IntPtr WindowProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
    {
        if (msg == NativeMethods.CS_DBLCLKS)
        {
            this.WindowState = WindowState.Minimized;
            // handled = true
        }

        return IntPtr.Zero;
    }

    /// <summary>

    internal class NativeMethods
    {
        public const int SC_RESTORE = 0xF120;
        public const int SC_MINIMIZE = 0xF020;
        public const int SC_CLOSE = 0xF060;
        public const int WM_SYSCOMMAND = 0x0112;
        public const int WS_SYSMENU = 0x80000;
        public const int WS_MINIMIZEBOX = 0x20000;
        public const int CS_DBLCLKS = 0x8;
        NativeMethods() { }
    }

使用ResizeMode="CanMinimize".这将允许您最小化到任务栏.
