title: Correct way to convert old SIGNAL and SLOT to new style?
body: <p>I'm currently trying to convert an old python program from Python 2 to Python 3, and update from PyQt4 to PyQt5. The application uses the old style signal and slots that are not supported under PyQt5. I have figured out most of what needs to be done, but below are a few lines that I can't seem to get working:</p>
  
  <pre><code>self.emit(SIGNAL('currentChanged'), row, col)
  self.emit(SIGNAL("activated(const QString &amp;)"), self.currentText())
  self.connect(self,SIGNAL("currentChanged(const QString&amp;)"), self.currentChanged)
  </code></pre>
  
  <p>The top two lines, I have no idea where to start since they don't seem to be attached to anything. The last example I'm not quite sure what to do with (<code>const QString &amp;</code>).</p>
  
  <p>I'm not entirely sure how to approach these, and I'm still learning python, but any help would be appreciated.</p>
  
  <p>EDIT: The documentation doesn't really seem to go into depth on these cases, at least in a way that I understand.</p>
