title: Custom frame for QLineEdit
body: <p>(Working with Qt 4.8.4)</p>
  
  <p>I'd like to create a custom frame for QLineEdit. One that has been created in photoshop and I have it in three images (as it needs to stretch in width):</p>
  
  <p><img src="https://i.stack.imgur.com/j1sba.png" alt="enter image description here"></p>
  
  <ol>
  <li>left side image</li>
  <li>center streetchable image</li>
  <li>right side image</li>
  </ol>
  
  <p>I'd like to find a way to replace the look of the QTLineEdit to this, while still retaining the edit visuals look/feel inside of it. It's just the frame I'm looking t replace.</p>
  
  <p>How do I go about it? If I override paintEvent nothing is visible, not even what I type, not even the blinking cursor.</p>
