can I draw a QTextEdit

[iGoo]

Sir,
I want to draw something in a QTextEdit's subclass in
PaintEvent,but fail.

Any suggestion will be appreciated .

It would be easier to help if you told us what exactly fails?
And maybe you could even supply a snippet of the paint event code and let us see if there's something wrong with it.

I want to draw a colorful rectangle around the user's
selection for text modifying.

But I fail when try the code snippet[drawing a rectangle or even a line] below.

void QHexEdn::paintEvent(QPaintEvent *e)
{
 
	//QTextEdit::paintEvent(e);
	QPainter pd(this);
	pd.setBrush(QBrush(QColor(255,255,255)));
	pd.drawRect(m_selRc);
	pd.setPen(QPen(QColor(255,0,0)));
	pd.drawLine(0,0,20,20);
 
//	QTextEdit::paintEvent(e);
 
}

void QHexEdn::paintEvent(QPaintEvent *e)
{
	
	//QTextEdit::paintEvent(e);
	QPainter pd(this);
	pd.setBrush(QBrush(QColor(255,255,255)));
	pd.drawRect(m_selRc);
	pd.setPen(QPen(QColor(255,0,0)));
	pd.drawLine(0,0,20,20);
	
//	QTextEdit::paintEvent(e);

}

To copy to clipboard, switch view to plain text mode

Initialize the painter on text edit's viewport:

QPainter pd(viewport());

QPainter pd(viewport());

To copy to clipboard, switch view to plain text mode
