TextBlock.LineStackingStrategy 属性

定义

命名空间:

System.Windows.Controls

程序集:

PresentationFramework.dll

获取或设置用于为 TextBlock 中的每行文本确定行框的机制。

public:
 property System::Windows::LineStackingStrategy LineStackingStrategy { System::Windows::LineStackingStrategy get(); void set(System::Windows::LineStackingStrategy value); };

public System.Windows.LineStackingStrategy LineStackingStrategy { get; set; }

member this.LineStackingStrategy : System.Windows.LineStackingStrategy with get, set

Public Property LineStackingStrategy As LineStackingStrategy

属性值

LineStackingStrategy

用于为 TextBlock 中的每行文本确定行框的机制。 默认值为 MaxHeight。

示例

下面的示例演示如何使用 LineStackingStrategy 属性来确定如何为文本行 TextBlock创建行框。 第一TextBlock个具有值MaxHeight，第二TextBlock个LineStackingStrategy值具有值BlockLineHeight。

<Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <StackPanel>
    
    <!-- This TextBlock has a LineStackingStrategy set to "MaxHeight". -->
    <TextBlock LineStackingStrategy="MaxHeight" LineHeight="10" Width="500" TextWrapping="Wrap" 
     Background="Yellow">
      Use the <Span FontSize="30">LineStackingStrategy</Span> property to determine how a line box is
      created for each line. A value of <Span FontSize="20">MaxHeight</Span> specifies that the stack
      height is the smallest value that contains all the inline elements on that line when those
      elements are properly aligned. A value of <Span FontSize="20">BlockLineHeight</Span> specifies
      that the stack height is determined by the block element LineHeight property value.
    </TextBlock>

    <!-- Here is the same TextBlock but the LineStackingStrategy is set to "BlockLineHeight". -->
    <TextBlock LineStackingStrategy="BlockLineHeight" LineHeight="10" Width="500" TextWrapping="Wrap" 
     Background="Blue" Margin="0,40,0,0">
      Use the <Span FontSize="30">LineStackingStrategy</Span> property to determine how a line box is
      created for each line. A value of <Span FontSize="20">MaxHeight</Span> specifies that the stack
      height is the smallest value that contains all the inline elements on that line when those
      elements are properly aligned. A value of <Span FontSize="20">BlockLineHeight</Span> specifies
      that the stack height is determined by the block element LineHeight property value.
    </TextBlock>

  </StackPanel>
</Page>

下图显示了上述代码的结果。

注解

此依赖属性还具有附加的属性用法。 在 XAML 中，用法是 <object TextBlock.LineStackingStrategy="value".../>， 对象是对象 元素 (通常是流元素) 包含在其中 TextBlock， 值 是枚举的 LineStackingStrategy 字符串值。 在代码中，附加的属性用法受以下支持 GetLineStackingStrategy 和 SetLineStackingStrategy支持。 附加属性用法不常见。
