title: How to properly Set Background Color of LWUIT Widget that is already themed?
body: <p>I tried the following code:</p>
  
  <pre><code>final Container root = getRootAncestor(c);
  TextArea resultBox = findResultBox(root);
  
  Style style = resultBox.getUnselectedStyle();
  style.setBgImage(null);
  style.setBgColor(0x00ff00);
  style.setFgColor(0xff0000);
  resultBox.setUnselectedStyle(style);
  resultBox.setSelectedStyle(style);
  </code></pre>
  
  <p>What works is only the font/foreground color, however the background color persists (it still uses the background image from the theme). I also tried:</p>
  
  <pre><code>style.setBackgroundType(Style.BACKGROUND_IMAGE_SCALED);
  style.setBgImage(Image.createImage(1, 1, 0x00ff00));
  </code></pre>
  
  <p>But this also doesn't work.</p>
  
  <p>Using LWUIT 1.5.</p>
