title: How to make a tip to follow the handler of slider with PyQT?
body: <p>A simple question, I am looking for a effect in pyqt like this:</p>
  
  <p><a href="https://stackoverflow.com/questions/8582564/jquery-ui-slider-how-to-make-a-box-follow-the-handler">Jquery UI slider how to make a box follow the handler?</a></p>
  
  <p>But those code is JQuery and I am trying to achieve it with PyQT</p>
  
  <pre><code>import sys
  from PyQt4 import QtGui, QtCore
  
  class Window(QtGui.QMainWindow):
  
      def __init__(self):
          super(Window, self).__init__()
          self.setGeometry(50, 50, 500, 500)
          self.setWindowTitle("PyQT example!")
          slider = QtGui.QSlider(self)
          slider.setOrientation(QtCore.Qt.Horizontal)
          slider.move(50, 50)
          slider.valueChanged.connect(self.value_changed)
          self.show()
  
      def value_changed(self, value):
          QtGui.QToolTip.showText(QtGui.QCursor.pos(), str(value), self)
  
  app = QtGui.QApplication(sys.argv)
  GUI = Window()
  sys.exit(app.exec_())
  </code></pre>
  
  <p>This code successfully made tip balloon follow the cursor.
  Now is it possible to make the tip follow my slider handler?</p>
