Enum

LineStackingStrategy

欄位

BlockLineHeight	0	堆疊高度是由區塊項目的文字行高度屬性值決定的。
MaxHeight	1	當這些項目正確對齊項目時，堆疊高度為包含線條上所有內嵌項目的最小值。

範例

下列範例示範如何使用 LineStackingStrategy 屬性來判斷如何為 的 TextBlock 文字行建立行框。 第一 TextBlock 個 LineStackingStrategy 具有 MaxHeight 的值，而第二 TextBlock 個值則為 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>
