如何让叙述者阅读WPF弹出框中的文本?

Question

我有一个WPF应用程序，其中包含一个按钮。当您按下按钮时，一个Popup打开。Popup包含有关会议的信息。

打开叙述者，不读取Popup的内容。我如何让叙述者阅读Popup的内容?

以下是Popup的内容示例:

<Popup x:Class="ClassApp.UserInterface.Views.Windows.Settings.MeetingDetailsPopup"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:converters="clr-namespace:MyApp.Converters"
xmlns:global="clr-namespace:"
Height="375"
mc:Ignorable="d"
MaxHeight="375"
MaxWidth="500" 
StaysOpen="True"
Placement="MousePoint" 
Width="500">
<Border BorderBrush="{StaticResource GrayBrush}"
Background="{StaticResource TabSelectedBackgroundBrush}"
BorderThickness="1">
<Grid Margin="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="25"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="35" />
<RowDefinition Height="35"/>
<RowDefinition Height="35"/>
<RowDefinition Height="35"/>
<RowDefinition Height="Auto"
MinHeight="100"/>
<RowDefinition Height="Auto"
MinHeight="40"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid Grid.Column="0"
Grid.ColumnSpan="3"
Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0"
AutomationProperties.AutomationId="ClassName"
AutomationProperties.Name="{Binding ClassName}"
FontSize="18"
FontWeight="Bold"
x:Name="ClassName"
Style="{StaticResource ClassInformationTextBlockStyle}"
Text="{Binding ClassName}"
TextWrapping="Wrap"
VerticalAlignment="Top"/>
<Button Grid.Column="1" 
AutomationProperties.Name="{x:Static languages:Resources.Accessibility_CloseWindow}"
AutomationProperties.AutomationId="CloseWindow"
Command="{Binding CloseMeetingInfoCommand}"
Content="X"
FontSize="16"
HorizontalAlignment="Right"
x:Name="CloseButton"
Style="{StaticResource ClassInformationCloseButtonStyle}"
VerticalAlignment="Top"/>
</Grid>
<TextBlock Grid.Column="0"
Grid.Row="1"
AutomationProperties.Name="{x:Static languages:Resources.Label_MeetingID}"
FontSize="14"
Foreground="{StaticResource GrayBrush}"
x:Name="MeetingIdLabel"
Style="{StaticResource ClassInformationTextBlockStyle}"
Text="{x:Static languages:Resources.Label_MeetingID}"
VerticalAlignment="Top"/>
<TextBlock Grid.Column="2"
Grid.Row="1"
AutomationProperties.AutomationId="MeetingId"
AutomationProperties.Name="{Binding MeetingID}"
AutomationProperties.LabeledBy="{Binding ElementName=MeetingIdLabel}"
FontSize="14"
Style="{StaticResource ClassInformationTextBlockStyle}"
Text="{Binding MeetingID}"
VerticalAlignment="Top"/>
. . .
</Grid>
</Grid>
</Border>
</Popup>

编辑:Popup的其余部分由更多的TextBlock和几个用于将链接或所有数据复制到剪贴板的按钮组成。我没有把它包括进去，因为我认为这无关紧要。

您需要设置弹出。IsKeyboardFocused为true。默认为false。

这将把选项卡焦点移到弹出窗口。只要记住，当用户关闭它时，您需要将焦点移回(最好是打开弹出窗口的触发器)。
