title: PyQt4.QtCore.pyqtSignal object has no attribute 'connect'
body: <p>I'm having issues with a custom signal in a class I made.</p>
  
  <p>Relevant code:</p>
  
  <pre><code>self.parse_triggered = QtCore.pyqtSignal()
  
  def parseFile(self):
      self.emit(self.parse_triggered)
  </code></pre>
  
  <p>Both of those belong to the class: RefreshWidget.
  In its parent class I have:</p>
  
  <pre><code>self.refreshWidget.parse_triggered.connect(self.tabWidget.giveTabsData())
  </code></pre>
  
  <p>When I try to run the program, I get the error:</p>
  
  <pre><code>AttributeError: 'PyQt4.QtCore.pyqtSignal' object has no attribute 'connect'
  </code></pre>
  
  <p>Help?
  Thanks in advance.</p>
