Class TabStop

  • java.lang.Object
    • com.aspose.words.TabStop
  • All Implemented Interfaces:
    java.lang.Cloneable
    public class TabStop 
    extends java.lang.Object

Represents a single custom tab stop. The TabStop object is a member of the TabStopCollection collection.

Normally, a tab stop specifies a position where a tab stop exists. But because tab stops can be inherited from parent styles, it might be needed for the child object to define explicitly that there is no tab stop at a given position. To clear an inherited tab stop at a given position, create a TabStop object and set Alignment to TabAlignment.Clear.

For more information see TabStopCollection.

Example:

Shows how to modify the position of the right tab stop in TOC related paragraphs.
Document doc = new Document(getMyDir() + "Table of contents.docx");

// Iterate through all paragraphs formatted using the TOC result based styles; this is any style between TOC and TOC9
for (Paragraph para : (Iterable<Paragraph>) doc.getChildNodes(NodeType.PARAGRAPH, true)) {
    if (para.getParagraphFormat().getStyle().getStyleIdentifier() >= StyleIdentifier.TOC_1
            && para.getParagraphFormat().getStyle().getStyleIdentifier() <= StyleIdentifier.TOC_9) {
        // Get the first tab used in this paragraph, this should be the tab used to align the page numbers
        TabStop tab = para.getParagraphFormat().getTabStops().get(0);
        // Remove the old tab from the collection
        para.getParagraphFormat().getTabStops().removeByPosition(tab.getPosition());
        // Insert a new tab using the same properties but at a modified position
        // We could also change the separators used (dots) by passing a different Leader type
        para.getParagraphFormat().getTabStops().add(tab.getPosition() - 50, tab.getAlignment(), tab.getLeader());
    }
}
