感谢Leom 的回答,我能够通过将FlowDocument包装在FlowDocumentReader中来将其添加到StackPanel中。

但是现在我有两个问题:

  • 似乎添加了第一个 FlowDocumentReader,其余的被忽略了
  • 有一个我无法摆脱的多余边距

如何在没有多余边距的情况下将多个 FlowDocumentReaders 添加到 StackPanel?

替代文字 http://www.deviantsart.com/upload/1ndiqqe.png

XAML:

<Window x:Class="TestFlowdoc23432.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="200" Width="300">
    <StackPanel Margin="10">
        <ContentControl x:Name="MainArea"/>
    </StackPanel>
</Window>

代码背后:

using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;

namespace TestFlowdoc23432
{
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();

            StackPanel sp = new StackPanel();

            TextBlock tb1 = new TextBlock();
            tb1.Text = "first text block";
            sp.Children.Add(tb1);

            TextBlock tb2 = new TextBlock();
            tb2.Text = "second text block";
            sp.Children.Add(tb2);

            sp.Children.Add(GetFlowDocumentReader("first flow document reader"));
            sp.Children.Add(GetFlowDocumentReader("second flow document reader"));

            MainArea.Content = sp;
        }

        FlowDocumentReader GetFlowDocumentReader(string text)
        {
            FlowDocumentReader fdr = new FlowDocumentReader();
            FlowDocument fd = new FlowDocument();
            fdr.Document = fd;
            fdr.Margin = new Thickness(0);
            Paragraph par = new Paragraph();
            par.Margin = new Thickness(0);
            fd.Blocks.Add(par);

            Run r = new Run(text);
            par.Inlines.Add(r);

            return fdr;
        }

    }
}

要使文本显示在左侧,您需要在 flowdocument 上设置 pagepadding 属性,如下所示:

fd.PagePadding = new Thickness(0);

您似乎只获得第一个阅读器的原因是因为它填充了可用空间(将其移动为第一个对象,您将看不到文本块)。如果将 FlowDocumentReader 更改为 FlowDocumentScrollViewer 并使用 VerticalScrollBarVisibility 属性,则可以获得所需的效果。以下是应用了更改的 GetFlowDocumentReader 方法:

FlowDocumentScrollViewer GetFlowDocumentReader(string text)
        {
            FlowDocumentScrollViewer fdr = new FlowDocumentScrollViewer();

            FlowDocument fd = new FlowDocument();
            fdr.Document = fd;
            fdr.Margin = new Thickness(0);
            Paragraph par = new Paragraph();
            par.Margin = new Thickness(0);
            fd.Blocks.Add(par);

            Run r = new Run(text);
            par.Inlines.Add(r);

            fd.PagePadding = new Thickness(0);
            fdr.VerticalScrollBarVisibility = ScrollBarVisibility.Hidden;

            return fdr;
        }
