LineStackingStrategy 枚举

定义

命名空间:

System.Windows

程序集:

PresentationFramework.dll

描述一种机制，将根据该机制来为每一行确定行框。

C#

public enum LineStackingStrategy

继承

Object

ValueType

Enum

LineStackingStrategy

字段

名称	值	说明
BlockLineHeight	0	堆栈高度由块元素行高属性值确定。
MaxHeight	1	当该行上所有内联元素均正确对齐时，堆栈高度是包含所有这些元素的最小值。

示例

以下示例演示如何使用 LineStackingStrategy 属性来确定如何为 的文本行 TextBlock创建行框。 第 TextBlock 一个 LineStackingStrategy 值为 MaxHeight，第二 TextBlock 个值为 BlockLineHeight。

XAML

<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>
