Getting real number of lines (lineCount) of a QTextDocument

The QTextDocument is rendering some HTML code and gets rendered on a QImage.
For some reason myDocument->lineCount() is returning the number of paragraphs but not the actual number of lines. The width of the QTextDocument is set and it is displayed correctly.

I saw some suggestion for converting the text to plaintext and count the newlines or something along the lines, but that is not satisfactory for me.

For now I am using the following code to get the number of lines abusing a textcursor, but I am wondering whether there is a better way to do that:

Code:

---

int CQtTextLayout::GetTotalLineCount( )
{
	int nReturnValue = 0;
 
	if( m_pTextCursor )
	{
		m_pTextCursor->movePosition( QTextCursor::Start );
		bool isNotDone = true;
		int lineCounter = 0;
		while( isNotDone )
		{
			isNotDone = m_pTextCursor->movePosition( QTextCursor::Down );
			lineCounter++;
		}
		DebugLog( "QT GetTotalLineCount %d", nReturnValue );
	}
 
	return nReturnValue;
}
