title: How to input character CR(Carriage Return) in QTextEdit?
body: <p>As we all know, QTextEdit can be used to input characters.
  Characters input by user can be got by QTextEdit::toPlainText().
  My application needs user to input character CR(Carriage Return) into QTextEdit.
  Can character CR be input into QTextEdit? 
  If it can, how to input it? 
  And how to get it from QTextEdit?
  Does QTextEdit::toPlainText() work?</p>
  
  <p>By the way, my application can get character LF(Line Feed) from QTextEdit by QTextEdit::toPlainText().
  Character CR can be input by pressing ctrl+M in CEdit(Edit Control) of MFC but it doesn't work for QTextEdit.</p>
  
  <p>Thanks for any idea.</p>
