Comment : utiliser les attributs de séparation de colonnes de FlowDocument

Mise à jour : novembre 2007

Cet exemple montre comment utiliser les fonctionnalités de séparation de colonnes de FlowDocument.

Exemple

L'exemple suivant définit un FlowDocument et définit les attributs ColumnGap, ColumnRuleBrush et ColumnRuleWidth. Le FlowDocument contient un paragraphe unique d'exemple de contenu.

<FlowDocumentReader>
  <FlowDocument 
    ColumnGap="20.0" 
    ColumnRuleBrush="DodgerBlue" 
    ColumnRuleWidth="5.0" 
    ColumnWidth="140.0"
>
    <Paragraph  Background="AntiqueWhite" TextAlignment="Left">
      This paragraph has the background set to antique white to make its
      boundaries obvious.

      The column gap is the space between columns; this FlowDocument will
      have a column gap of 20 device-independend pixels.  The column rule
      is a vertical line drawn in the column gap, and is used to visually
      separate columns; this FlowDocument a Dodger-blue column rule that
      is 5 pixels wide.

      The column rule and column gap both take space between columns.  In
      this case, a column gap width of 20 plus a column rule of width of 5
      results in the space between columns being 25 pixels wide, 5 pixels
      for the column rule, and 10 pixels of column gap on either side of the column rule.
    </Paragraph>
  </FlowDocument>
</FlowDocumentReader>

L'illustration suivante montre les effets des attributs ColumnGap, ColumnRuleBrush et ColumnRuleWidth dans un FlowDocument rendu.
