title: Get plain text from QLineEdit
body: <p>I want to retrieve plain text from <code>QLineEdit()</code> object. The text method returns a <code>QString</code> object. I just want a simple string object.
  I am using pyqt4.</p>
  
  <pre><code>def n(self):
      new_label=QLineEdit()
      new_label.setText("txt")
      txt=self.new_label.text()
      self.name=txt
  </code></pre>
  
  <p>txt should be a simple string not <code>QString</code>.</p>
