How can I paint a line in TextEdit on QT-4.3.2?

If "<hr/>" is insufficient, you can always reimplement its paintEvent() and open a QPainter on its viewport().

Other variant on svg xml you can create any Form and color image line round rect ecc...
and insert on document and direct insert... at end only save to png or other...
