How to: Use FlowDocument Column-Separating Attributes
This example shows how to use the column-separating features of a FlowDocument.
<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>
The following figure shows the effects of the ColumnGap, ColumnRuleBrush, and ColumnRuleWidth attributes in a rendered FlowDocument.
