高级FlowDocument内容

正如我已经提到，WPF的FlowDocument的文本显示功能非常丰富 - 你几乎可以做任何事情，这包括列表，图像甚至表格等内容。 到目前为止，我们已经使用了FlowDocument内容的非常基础的示例，但在本文中，我们最终将做一个更全面的示例。

下一个示例的XAML代码可能看起来很复杂，但它实际上很简单 - 就像HTML一样，您可以简单地将它们放在样式段落中来格式化文本。 现在来看看XAML。 结果的屏幕截图将紧跟在它之后：

<Window x:Class="WpfTutorialSamples.Rich_text_controls.ExtendedFlowDocumentSample"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="ExtendedFlowDocumentSample" Height="550" Width="500">
    <Grid>
        <FlowDocumentScrollViewer>
            <FlowDocument>
                <Paragraph>
                    <Image Source="http://www.wpf-tutorial.com/images/logo.png" Width="90" Height="90" Margin="0,0,30,0" />
                    <Run FontSize="120">WPF</Run>
                </Paragraph>

                <Paragraph>
                    WPF, which stands for
                    <Bold>Windows Presentation Foundation</Bold>,
                    is Microsoft's latest approach to a GUI framework, used with the .NET framework.
                    Some advantages include:
                </Paragraph>

                <List>
                    <ListItem>
                        <Paragraph>
                            It's newer and thereby more in tune with current standards
                        </Paragraph>
                    </ListItem>
                    <ListItem>
                        <Paragraph>
                            Microsoft is using it for a lot of new applications, e.g. Visual Studio
                        </Paragraph>
                    </ListItem>
                    <ListItem>
                        <Paragraph>
                            It's more flexible, so you can do more things without having to write or buy new controls
                        </Paragraph>
                    </ListItem>
                </List>

                <Table CellSpacing="0">
                    <TableRowGroup>
                        <TableRow Background="Gainsboro" FontWeight="Bold">
                            <TableCell></TableCell>
                            <TableCell>
                                <Paragraph TextAlignment="Right">WinForms</Paragraph>
                            </TableCell>
                            <TableCell>
                                <Paragraph TextAlignment="Right">WPF</Paragraph>
                            </TableCell>
                        </TableRow>
                    </TableRowGroup>

                    <TableRowGroup>
                        <TableRow>
                            <TableCell Background="Gainsboro" FontWeight="Bold">
                                <Paragraph>Lines of code</Paragraph>
                            </TableCell>
                            <TableCell>
                                <Paragraph TextAlignment="Right">1.718.000</Paragraph>
                            </TableCell>
                            <TableCell>
                                <Paragraph TextAlignment="Right">1.542.000</Paragraph>
                            </TableCell>
                        </TableRow>
                    </TableRowGroup>
                    <TableRowGroup>
                        <TableRow>
                            <TableCell Background="Gainsboro" FontWeight="Bold">
                                <Paragraph>Developers</Paragraph>
                            </TableCell>
                            <TableCell>
                                <Paragraph TextAlignment="Right">633.000</Paragraph>
                            </TableCell>
                            <TableCell>
                                <Paragraph TextAlignment="Right">981.000</Paragraph>
                            </TableCell>
                        </TableRow>
                    </TableRowGroup>
                </Table>
                <Paragraph Foreground="Silver" FontStyle="Italic">A table of made up WinForms/WPF numbers</Paragraph>
            </FlowDocument>
        </FlowDocumentScrollViewer>
    </Grid>
</Window>

我不会过多的深入每个标签的细节 - 希望它们应该如此。

如您所见，包括列表，图像和表格非常简单，事实上，您可以在FlowDocument中包含任何WPF控件。 使用BlockUIContainer元素包含他们，您可以访问所有控件，否则这些控件只能在窗口中使用。 这是一个例子：

<Window x:Class="WpfTutorialSamples.Rich_text_controls.BlockUIContainerSample"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:self="clr-namespace:WpfTutorialSamples.Rich_text_controls"
        Title="BlockUIContainerSample" Height="275" Width="300">
    <Window.Resources>
        <x:Array x:Key="UserArray" Type="{x:Type self:User}">
            <self:User Name="John Doe" Age="42"/>
            <self:User Name="Jane Doe" Age="36"/>
        </x:Array>
    </Window.Resources>
    <Grid>
        <FlowDocumentScrollViewer>
            <FlowDocument>
                <Paragraph FontSize="36" Margin="0">Users</Paragraph>
                <Paragraph FontStyle="Italic" TextAlignment="Left" FontSize="14" Foreground="Gray">Here's a list of our users, inside our FlowDocument, in a completely interactive ListView control!</Paragraph>
                <BlockUIContainer>
                    <ListView BorderThickness="0" ItemsSource="{StaticResource UserArray}">
                        <ListView.View>
                            <GridView>
                                <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}" Width="150" />
                                <GridViewColumn Header="Age" DisplayMemberBinding="{Binding Age}" Width="75" />
                            </GridView>
                        </ListView.View>
                    </ListView>
                </BlockUIContainer>
                <Paragraph FontStyle="Italic" TextAlignment="Left" FontSize="14" Foreground="Gray">More content can go here...</Paragraph>
            </FlowDocument>
        </FlowDocumentScrollViewer>
    </Grid>
</Window>

现在我们有一个带有ListView的FlowDocument，正如你从屏幕截图中看到的那样，ListView就像通常那样工作，包括选择等等。非常酷！

小结

通过使用本文两个示例中描述的技术，创建FlowDocument文档可以做任何事情。 它非常适合向最终用户呈现可视化信息，就像许多昂贵的报表套件那样。
