Yes, indeed.  Using QTextEdit with its ensureCursorVisible() method
solves the backup problem.  Text flows without trouble from start to end
(3,000+ lines) while the output is generated.  Thanks for the
suggestion, Josi!

I have a minor issue, however.  I'm trying to insertHtml() on the
QTextEdit, but all I'm getting is the text itself without any of the
formatting.  For example, the HTML you provided (above) just shows up as
"Hello World!" in black on the white background.  My icon is not being
displayed, and the color selections appear to be ignored.  Is there some
kind of additional setup I need to perform on the QTextEdit to get it to
properly process HTML text?
