LineStackingStrategy 枚举

定义

描述一种机制,将根据该机制来为每一行确定行框。Describes a mechanism by which a line box is determined for each line.

public enum class LineStackingStrategy
public enum LineStackingStrategy
type LineStackingStrategy = 
Public Enum LineStackingStrategy
继承
LineStackingStrategy

字段

BlockLineHeight 0

堆栈高度由块元素行高属性值确定。The stack height is determined by the block element line-height property value.

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。The stack height is the smallest value that containing all the inline elements on that line when those elements are properly aligned.

示例

下面的示例演示如何使用LineStackingStrategy属性来确定如何为的文本行TextBlock创建行框。The following example shows how to use the LineStackingStrategy property to determine how the line boxes are created for text lines of a TextBlock. 第一个TextBlock LineStackingStrategy值为 system.windows.frameworkelement.maxheight, 第二个TextBlock值的值为 BlockLineHeight。The first TextBlock has a LineStackingStrategy value of MaxHeight and the second TextBlock has a value of BlockLineHeight.

    <!-- This TextBlock has a LineStackingStrategy set to "MaxHeight". -->
    <TextBlock LineStackingStrategy="MaxHeight" LineHeight="10" Width="500" TextWrapping="Wrap"

      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

      height is the smallest value that contains all the inline elements on that line when those
