title: Background-image in Qt stylesheet doesn't work
body: <p>This should set the background to cats.jpg, but it doesn't do anything:</p>
  
  <pre><code>int main(int argc, char *argv[])
  {
      QApplication a(argc, argv);
      Widget w; 
      w.setStyleSheet("background-image: url(images/ricepaper.png);");;
  
      w.show();
  
      return a.exec();
  }
  </code></pre>
  
  <p>I thought that it could be a problem with the image location since changing the widget's background-color works fine, but the images folder is in the build-debug directory which I believe is the correct place. I've tried changing the image path, syntax, and styleSheet class and nothing has worked, any suggestions?</p>
