title: PyQt, Any way to use one changeValue method for multiple sliders?
body: <p>I need to have 3 sliders (or more). So at the moment, I have three different changeValues methods for each slider. </p>
  
  <p>In initUI(self), I have three sliders:</p>
  
  <pre><code>    sigmaTitle = QtGui.QLabel('Sigma')
      sigmaSlider = QtGui.QSlider(QtCore.Qt.Horizontal, self)
      sigmaSlider.setRange(0, 100)
      sigmaSlider.valueChanged[int].connect(self.sigmaChangeValue)
  
      dtTitle = QtGui.QLabel('Sigma')
      dtSlider = QtGui.QSlider(QtCore.Qt.Horizontal, self)
      dtSlider.setRange(200, 400)
      dtSlider.valueChanged[int].connect(self.dtChangeValue)
  
      rTitle = QtGui.QLabel('Sigma')
      rSlider = QtGui.QSlider(QtCore.Qt.Horizontal, self)
      rSlider.setRange(300, 400)
      rSlider.valueChanged[int].connect(self.rChangeValue)
  </code></pre>
  
  <p>Then I have three changeValue methods:</p>
  
  <pre><code>def sigmaChangeValue(self, value):
      self.sigma = value / 1000.0
      print self.sigma
  
  def dtChangeValue(self, value):
      self.dt = value / 1000.0
      print self.dt
  
  def rChangeValue(self, value):
      self.r = value / 1000.0
      print self.r
  </code></pre>
  
  <p>so is there a way to use one share changeValue method and still allow to individually assign variable with different range?</p>
  
  <p>Thanks </p>
