WPF萌新求助

[罗宇翔]

我该怎么实现上面两个图中，中间那个可编辑文档的效果呢，看上去是个window控件，但是不能添加window。

WPF中没有window控件，只有window根节点或者window窗体。编辑效果就使用可编辑控件，textbox即可，不过你需要做的是写一个带下 划线样式的自定义textbox。不清楚网上搜索 textbox style/template 或者 "wpf 如何让textbox只显示下划线".

        public MainWindow()
        {
            InitializeComponent();
            
            Loaded += MainWindow_Loaded;
        }

        private void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            Window win = new Window();
            win.Owner = this;
            win.Show();
            Win32Api.SetParent(new WindowInteropHelper(win).Handle, new WindowInteropHelper(this).Handle);
        }  

    public class Win32Api
    {

        #region Consts

        #endregion 

        #region Public Methods

        [DllImport("user32.dll", SetLastError = true)]
        public static extern int SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

        [DllImport("user32.dll", SetLastError = true)]
        public static extern bool MoveWindow(IntPtr hwnd, int x, int y, int cx, int cy, bool repaint);

        #endregion


    }

不知道你要的是不是这个效果

    public partial class MainWindow : Window
    {

        private Window win = null;

        public MainWindow()
        {
            InitializeComponent();
            
            Loaded += MainWindow_Loaded;
        }

        private void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            win = new Window();
            win.Owner = this;
            win.Show();
            Win32Api.SetParent(new WindowInteropHelper(win).Handle, new WindowInteropHelper(this).Handle);
            Win32Api.MoveWindow(new WindowInteropHelper(win).Handle, 0, 0, (int)ActualWidth, (int)ActualHeight, true);
        }

        protected override void OnRender(DrawingContext drawingContext)
        {
            if (win != null)
            {
                Win32Api.MoveWindow(new WindowInteropHelper(win).Handle, 0, 0, (int)ActualWidth, (int)ActualHeight, true);
            }
            base.OnRender(drawingContext);
        }

        protected override void OnRenderSizeChanged(SizeChangedInfo sizeInfo)
        {
            this.InvalidateVisual();
            base.OnRenderSizeChanged(sizeInfo);
        }
    }
