title: How to change cursor shape of QPlainTextEdit (Pyqt, PySide)
body: <p>I have a simple Qt widget contains of a <code>QPlainTextEdit</code>. I only want to display text so I disabled text interaction. Now I want to change the cursor shape to the normal <code>Qt.ArrowCursor</code>. I tried:</p>
  
  <pre><code>self.disp = QPlainTextEdit()
  self.disp.setTextInteractionFlags(Qt.NoTextInteraction)
  self.disp.setCursor(Qt.ArrowCursor)
  </code></pre>
  
  <p>but it doesn't work. </p>
  
  <p>PS: I don't want to use:</p>
  
  <pre><code>QApplication.setOverrideCursor(QCursor(Qt.ArrowCursor))
  </code></pre>
  
  <p>as I actually have other widgets in the application and I don't want to affect them.</p>
