title: Placeholder text not showing (pyside/pyqt)
body: <p>Learning PySide, I'm tweaking a text edit widget (QLineEdit) and trying to set the placeholder text using setPlaceHolderText as in the code snippet below (which I invoke from <code>main</code>). Unfortunately, it is not working as I expected. The code runs, but the text box is blank, does not show the placeholder text. I am in Windows 7, Python 2.7 (working in iPython). </p>
  
  <pre><code>class MyTextEdit(QtGui.QWidget):
      def __init__(self):
          QtGui.QWidget.__init__(self)
          self.textEditor=QtGui.QLineEdit(self) 
          self.textEditor.move(50,15)
          self.textEditor.setPlaceholderText("Don't mind me.") 
          self.setGeometry(100, 100, 200, 50)
          self.show()        
  </code></pre>
  
  <p>Anyone understand what I'm doing wrong? I'm following examples from the following sites:</p>
  
  <p><a href="http://nullege.com/codes/search/PyQt4.QtGui.QLineEdit.setPlaceholderText" rel="noreferrer">http://nullege.com/codes/search/PyQt4.QtGui.QLineEdit.setPlaceholderText</a></p>

  <p>And don't see what I'm doing differently.</p>
