This is turning into quite an educational project for me.
w.repaint() does *not* involve QSH, so the QTextBrowser must cache the
style info. The question is, where?
To answer this, I looked at the QSH sources. The answer, apparently,
is in a QTextLayout. Indeed, in QSH.applyFormatChanges() there is the
line::
QTextLayout *layout = currentBlock.layout();
and right near the end::
layout->setAdditionalFormats(ranges);
So it should be possible to write a short script to get a concise
summary of the formatting. I might even dare hope that QTextLayout
may simplify the process. We shall see...
