To call the base class paint event, your text browser class' paint event 
should look like this:

void text_browser::paintEvent(QPaintEvent *e)
{
	QTextBrowser::paintEvent(e);
	QPainter painter;
	painter.setPen(Qt::red);
	painter.drawRect(100,100,100,100);
}

I don't think calling accept() makes any difference for paint events.
