Tab stop support for RTF

[rmcdonald]

I'm working on applications using Windows Presentation Foundation. I'm using System.Windows.Controls.RichTextBox to display RTF generated by MigraDoc by calling RtfDocumentRenderer.RenderToString() and then calling RichTextBox.SelectAll() and RichTextBox.Selection.Load(). The displayed RTF document looks as I expect, except for the absence of tab stops. In contrast, the PDF file I generate from the same MigraDoc.DocumentObjectModel.Document looks as I expect, including tab stops.

I'm declaring tab stops as follows:

        style = docReport.Styles.AddStyle("TabbedTwoColumnPairs", "Normal");
        style.ParagraphFormat.TabStops.Clear();
        style.ParagraphFormat.TabStops.AddTabStop("4cm");
        style.ParagraphFormat.TabStops.AddTabStop("8cm");
        style.ParagraphFormat.TabStops.AddTabStop("12cm");

Searching the web, I found that there is also System.Windows.Forms.RichTextBox, but that is apparently only for applications using Windows Forms. That class has a SelectionTabs property that allows specification of tab stops. System.Windows.Controls.RichTextBox does not support this property.

Is there another way to specify tab stops using MigraDoc, or does this MigraDoc feature depend on using it with a System.Windows.Forms.RichTextBox and some code outside of the development of a Document instance? Running find . -type f -name "*.cs" | xargs grep -H SelectionTabs within the master branch of the PDFsharp repo doesn't show any rows.

Tab stops work when watching the RTF with e.g. Microsoft Word.
I guess that RichTextBox has some limitations with respect to tab stops.
