WPF：將路徑應用於文本框模板

Question

在Blend中，我創建了一個看起來像氣泡的路徑。 我想將此路徑用作TextBox或TextBlock的樣式或模板（我不在乎，因為它將始終用於只讀文本）。 如何將路徑應用於TextBox或TextBlock以創建自己的樣式或模板？

XAML路徑：

<Path Data="M27.499998,2.5 L218,2.5 C231.80711,2.5000005 243,13.692882 243,27.500002 L243,114.5 C243,128.30711 231.80711,139.5 218,139.5 L176.86046,139.5 176.77534,140.60143 C173.04614,179.27731 126.53165,183.52524 126.53165,183.52524 143.526,165.98947 145.27682,147.30386 145.22961,139.96802 L145.222,139.5 27.499998,139.5 C13.692882,139.5 2.5,128.30711 2.5,114.5 L2.5,27.500002 C2.5,13.692882 13.692882,2.5000005 27.499998,2.5 z" 
      Fill="#FF5E9E5B" 
      HorizontalAlignment="Left" 
      Height="186.025" 
      Stretch="Fill" 
      Stroke="Black" 
      StrokeThickness="5" 
      VerticalAlignment="Top" 
      Width="245.5" />

解決方案：（由於克里斯·W。回答）

萬一有人碰到這個問題，這就是我實施解決方案的方法，以創建一個自動調整內容大小的文本框氣泡。

在StylesDictionary.xaml中：

<Style x:Key="SpeechBubbleTextBoxStyle" TargetType="{x:Type ContentControl}">
    <Setter Property="IsTabStop" Value="False" />
    <Setter Property="HorizontalContentAlignment" Value="Left" />
    <Setter Property="VerticalContentAlignment" Value="Top" />
    <Setter Property="Margin" Value="10" />
    <!-- Add additional Setters Here -->
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ContentControl}">
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition />
                        <RowDefinition />
                    </Grid.RowDefinitions>
                    <TextBox Text="{TemplateBinding Content}" 
                             VerticalAlignment="Top" 
                             HorizontalAlignment="Stretch"
                             Padding="10"
                             TextWrapping="Wrap"
                             BorderBrush="Black" 
                             BorderThickness="2" 
                             Background="#FF5E9E5B"
                             Grid.Row="0">
                        <TextBox.Resources>
                            <Style TargetType="{x:Type Border}">
                                <Setter Property="CornerRadius" Value="15" />
                                <Setter Property="BorderBrush" Value="Black" />
                                <Setter Property="BorderThickness" Value="3" />                                            
                            </Style>
                        </TextBox.Resources>
                    </TextBox>
                    <Path Data="M332,212.5 C332,250.00012 294.00041,254.50014 294.00041,254.50014 312.91688,228.75005 308.39508,212.54091 308.39508,212.54091" 
                          Fill="#FF5E9E5B" 
                          HorizontalAlignment="right" 
                          VerticalAlignment="Top" 
                          Height="34" 
                          Width="43" 
                          Margin="0,-3,50,0"
                          Stretch="Fill" 
                          Stroke="Black" 
                          StrokeThickness="2" 
                          UseLayoutRounding="True"
                          Grid.Row="1"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

然后在我的UserControl中這樣稱呼它：

    <ContentControl Style="{StaticResource SpeechBubbleTextBoxStyle}"
                    Content="{Binding InstructionsText}" />    

結果看起來像這樣：

如果是我，我會把它塞進類似的模板中；

<Window.Resources>
    <Style x:Key="ChatBubbleThingy" TargetType="{x:Type ContentControl}">
        <Setter Property="IsTabStop" Value="False"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="Padding" Value="10"/>
            <!-- Add additional Setters Here -->
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ContentControl}">
                    <Grid>
                        <Path Data="M27.499998,2.5 L218,2.5 C231.80711,2.5000005 243,13.692882 243,27.500002 L243,114.5 C243,128.30711 231.80711,139.5 218,139.5 L176.86046,139.5 176.77534,140.60143 C173.04614,179.27731 126.53165,183.52524 126.53165,183.52524 143.526,165.98947 145.27682,147.30386 145.22961,139.96802 L145.222,139.5 27.499998,139.5 C13.692882,139.5 2.5,128.30711 2.5,114.5 L2.5,27.500002 C2.5,13.692882 13.692882,2.5000005 27.499998,2.5 z" 
                              Fill="#FF5E9E5B"
                              Height="186.025" 
                              Stretch="Fill" 
                              Stroke="Black" 
                              StrokeThickness="5"
                              Width="245.5" />
                        <TextBlock Text="{TemplateBinding Content}" 
                                   Margin="{TemplateBinding Padding}" 
                                   VerticalAlignment="{TemplateBinding VerticalContentAlignment}" 
                                   HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"/>
                    </Grid>                             
                </ControlTemplate>
            </Setter.Value>
        </Setter>                      
    </Style>
</Window.Resources>

然后像這樣調用它；

<ContentControl Style="{StaticResource ChatBubbleThingy}" 
                Content="Blah Blah Blah Blah"/>

您必須對其進行一些調整才能使其完全按照您的要求顯示，但是您明白了。 希望這會有所幫助，歡呼。

PS-如果您想將其放入TextBox模板中，或者也很簡單。
