c# - 在流文档或 WPF RichTextBox 中创建悬挂缩进

Question

有没有办法在流程文档或 system.windows.control RichTextBox(wpf) 中创建悬挂缩进？如果它可以在流程文档中工作，当我将其加载到 RichTextBox 中以显示它时，它会保持其形式吗？

Answer 1

在 FlowDocument 段落定义中，您可以将左边距设置为悬挂缩进值，然后将 TextIndent 设置为该值的负数。下面是一个例子:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />
    </Grid.RowDefinitions>

    <FlowDocumentScrollViewer>
        <FlowDocument>
            <Section>
                <Paragraph TextIndent="-30" Margin="30,20,0,0">
                    The first line of this paragraph is not indented, but the rest of the lines will be indented by 30 units. The first line of this paragraph is not indented, but the rest of the lines will be indented by 30 units.
                </Paragraph>
            </Section>
        </FlowDocument>
    </FlowDocumentScrollViewer>

    <RichTextBox Grid.Row="1">
        <FlowDocument>
            <Section>
                <Paragraph TextIndent="-60" Margin="60,20,0,0">
                    The first line of this paragraph is not indented, but the rest of the lines will be indented by 60 units. The first line of this paragraph is not indented, but the rest of the lines will be indented by 60 units.
                </Paragraph>
            </Section>
        </FlowDocument>
    </RichTextBox>
</Grid>
