title: flex - how to set the background color of a spark check box text label?
body: <p>I have a simple spark mxml check box and I want to change the background color via actionscript.    I have searched and tried many suggestions, including using setStyle with 'background-color', 'chromeColor', symbolColor and others like this - the only thing that worked at all is chromeColor, which colored the box but not the text or background:</p>
  
  <pre><code>insUpdatedCB.setStyle('chromeColor','yellow');
  </code></pre>
  
  <p>I also tried using text format like this:</p>
  
  <pre><code>var myTf:TextFormat = new TextFormat();
  myTf.size = 16; 
  myTf.color = 0xFF0000; 
  insUpdatedCB.setStyle("textFormat", myTf);  
  </code></pre>
  
  <p>also did not work</p>
  
  <p>how can I set the label/text background color?</p>
