title: TinyMCE 4 default font-size
body: <p>In TinyMCE 3 you can change the editor's default font-size by using this code in the settings:</p>
  
  <pre><code>setup : function(ed)
  {
      ed.onInit.add(function(ed)
          {
              ed.getDoc().body.style.fontSize = '14px';
          });
  }
  </code></pre>
  
  <p>In version 4, I tried using the same method but get this error:</p>
  
  <blockquote>
    <p>TypeError: ed.onInit is undefined</p>
  </blockquote>
  
  <p>I also tried using the "content_css" option and set the body to 14px font size, but that works only when on preview. <a href="http://www.tinymce.com/wiki.php/Configuration:content_css" rel="nofollow">http://www.tinymce.com/wiki.php/Configuration:content_css</a></p>
  
  <p>Has anyone found another way to set the editor's default font size? I couldn't find any documents, even in their forum.</p>
