範例

下列範例示範如何設定 Padding 專案的屬性 Block (Paragraph) 。

<FlowDocument Background="LightSlateGray" ColumnWidth="2000">
  <Section Background="DarkMagenta" Margin="0" Padding="0">
    <Paragraph Background="White">
      <Run>Default paragraph.</Run>
    </Paragraph>
    <Paragraph Background="White">
      <Run>Default paragraph.</Run>
    </Paragraph>
    <Paragraph Background="LightBlue" Margin="50">
      <Run>This paragraph has a magin of 50 pixels set, but no padding.</Run>
    </Paragraph>
    <Paragraph Background="LightCoral" Padding="50">
      <Run>This paragraph has padding of 50 pixels set, but no margin.</Run>
    </Paragraph>
    <Paragraph Background="LightGreen" Margin="50" Padding="50">
      <Run>This paragraph has both padding and margin set to 50 pixels.</Run>
    </Paragraph>
    <Paragraph Background="White">
      <Run>Default paragraph.</Run>
    </Paragraph>
    <Paragraph Background="White">
      <Run>Default paragraph.</Run>
    </Paragraph>
  </Section>
</FlowDocument>

下列範例示範如何以程式設計方式設定 Padding 屬性。

XAML Attribute Usage

<object Padding="uniformThickness"/>  
- or -  
<object Padding="independentThickness"/>  
- or -  
<object Padding="qualifiedUniformThickness"/>  
- or -  
<object Padding="qualifiedIndependentThickness"/>  

XAML 值

uniformThickness
單 Double 一值的字串表示，以統一套用至這四個粗細尺寸。 例如，的值 "10" 相當於 的值 "10,10,10,10" 。 不合格的值是以裝置獨立圖元來測量。 字串不需要明確包含小數點。

independentThickness
四個已排序 Double 值的字串表示，以這個順序對應至左、上、右和下的獨立粗細維度。 四個值必須以逗號分隔;不允許空格。 例如，「5，10，15，20」 會產生 5 圖元的填補到內容左邊、內容上方 10 圖元填補、內容右邊 15 圖元填補，以及內容下方 20 圖元的填補。

qualifiedUniformThickness
uniformThickness 所描述的值，後面接著下列其中一個單位規範： px 、 in 。

px (預設) 是裝置獨立單位 (每單位 1/96 英吋)

in 為英吋;1in==96px

例如， "1in" 提供所有方向 1 英吋的統一邊框間距。

qualifiedIndependentThickness
independentThickness 所描述的值，每個獨立值後面接著下列其中一個單位規範： px 、 in 。

px (預設) 是裝置獨立單位 (每單位 1/96 英吋)

in 為英吋;1in==96px

例如： "1.5in,0.8in,1.5in,0.8in" 。 單位規範可以混合或省略一或多個值。
