#Remarks
The following code snippet illustrates the use of a MeasureSingleLineString method, to calculate required size of a tab stop. The tab stop position is specified by the TabInfo.Position property and measured in units of a current document (Document.Unit value). To provide uniform tab stops for a certain number of characters, a monospaced font is selected as the default document font.
DevExpress.XtraRichEdit.API.Native.Document document = richEditControl1.Document;
SizeF tabSize = richEditControl1.MeasureSingleLineString(new String('w', 4), document.DefaultCharacterProperties);
DevExpress.XtraRichEdit.API.Native.TabInfoCollection tabs = document.Paragraphs[0].BeginUpdateTabs(true);
try
{
for (int i = 1; i <= 30; i++)
{
DevExpress.XtraRichEdit.API.Native.TabInfo tab = new DevExpress.XtraRichEdit.API.Native.TabInfo();
tab.Position = i * tabSize.Width;
tabs.Add(tab);
}
}
finally
{
document.Paragraphs[0].EndUpdateTabs(tabs);
}
