ExtendScript: How to get the distance to the side of the text frame

Question

Hi,I have an index. The page numbers are right-aligned with a tab to the right side of the text frame.When the text extends too far to the page number area, I want to insert a line break.I can get the TextRange or the TextLoc of the single characters in the text.However, I do not know how to get the distance to the text frame border.I did not find any LocX property of the TextRange or the TextLoc.How can I tackle this? Which object and which property do I have to check?Thank you very much for your help!Best regards, Winfried

I found this function in my collection. It takes a text range--for example, the tab before the page number--and calculates its width. If it's smaller than a certain threshhold, then you can do something like break the line.function getTextRangeWidth (textRange, doc) {    var PT, prop, beginOffset, endOffset;    PT = 65536; // 1 point.    prop = doc.GetTextPropVal (textRange.beg, Constants.FP_LocX);    beginOffset = prop.propVal.ival / PT;    prop = doc.GetTextPropVal (textRange.end, Constants.FP_LocX);    endOffset = prop.propVal.ival / PT;    return endOffset - beginOffset;}

Getting properties from a TextLoc require the GetTextPropVal document function:

// doc = Doc object; and textLoc = TextLoc object.
prop = doc.GetTextPropVal (textLoc, Constants.FP_LocX);
// Get the value in metric units.
value = prop.propVal.ival;
// Convert it to points.
value = value / 65536;
