Draw text as selected throw TRVReportHelper

[vit]

Hi!
I using TRVReportHelper for drawing RTF text on Canvas. I want to represent selection a part of text by highlight. So how I can do it?
May be I can get somehow rectangles of all selected lines with offsets?

Thank you for any help!

TRVReportHelper does not support drawing selection.
You need either modifying the document before to change background colors, or use TRVStyle's custom drawing events (such as OnDrawStyleText)
