Remarks

In Microsoft Word documents, a tab stop can be defined in the properties of a paragraph style or directly in the properties of a paragraph. A style can be based on another style. Therefore, the complete set of tab stops for a given object is a combination of tab stops defined directly on this object and tab stops inherited from the parent styles.

In Aspose.Words, when you obtain a TabStops collection for a paragraph or a style, it contains only the custom tab stops defined directly for this paragraph or style. The collection does not include tab stops defined in the parent styles or default tab stops.

Examples
Shows how to add tab stops to a document.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Access the collection of tab stops and add some tab stops to it
TabStopCollection tabStops = builder.ParagraphFormat.TabStops;

// 72 points is one "inch" on the Microsoft Word tab stop ruler
tabStops.Add(new TabStop(72.0));
tabStops.Add(new TabStop(432.0, TabAlignment.Right, TabLeader.Dashes));

Assert.AreEqual(2, tabStops.Count);
Assert.IsFalse(tabStops[0].IsClear);
Assert.IsFalse(tabStops[0].Equals(tabStops[1]));

builder.Writeln("Start\tTab 1\tTab 2");

// Get the collection of paragraphs that we've created
ParagraphCollection paragraphs = doc.FirstSection.Body.Paragraphs;
Assert.AreEqual(2, paragraphs.Count);

// Each paragraph gets its own TabStopCollection which gets values from the DocumentBuilder's collection
Assert.AreEqual(paragraphs[0].ParagraphFormat.TabStops, paragraphs[1].ParagraphFormat.TabStops);
Assert.AreNotSame(paragraphs[0].ParagraphFormat.TabStops, paragraphs[1].ParagraphFormat.TabStops);
Assert.AreNotEqual(paragraphs[0].ParagraphFormat.TabStops.GetHashCode(),
    paragraphs[1].ParagraphFormat.TabStops.GetHashCode());

// A TabStopCollection can point us to TabStops before and after certain positions
Assert.AreEqual(72.0, tabStops.Before(100.0).Position);
Assert.AreEqual(432.0, tabStops.After(100.0).Position);

doc.Save(ArtifactsDir + "TabStopCollection.TabStops.docx");
