Promoting QLabel

void paintEvent ( QPaintEvent * event )
{
	QTextEdit::paintEvent(event);
        QPainter painter(viewport());
	painter.setPen(Qt::blue);
	painter.drawLine(rect().topLeft(),rect().bottomRight());
}

void paintEvent ( QPaintEvent * event )
{
	QTextEdit::paintEvent(event);
        QPainter painter(viewport());
	painter.setPen(Qt::blue);
	painter.drawLine(rect().topLeft(),rect().bottomRight());
}

To copy to clipboard, switch view to plain text mode 

It is working fine. I am forgotten to call viewport() and paintEvent inside paintEvent(). Thanks for your kind help.
