Hello,

I'm still testing the Button feature. It seems that inputs of type "submit" don't accept icons.
According to this quote from the official overview, adding an icon could be possible :

Button enhances standard form elements like button, input of type submit or reset or anchors to themable buttons with appropiate mouseover and active styles.

I ran the following code :

1. <p>
     <button class="button" type="button">Button</button>
   </p>
   <p>
     <input class="button" type="checkbox" id="checkbox" />
     <label for="checkbox">Checkbox</label>
   </p>
   <p>
     <input class="button" type="submit" value="Submit" />
   </p>
   
   <script type="text/javascript">
   $('.button').button({icons: {primary:'ui-icon-gear'} });
   </script>
   
   
   
   
   
   
   
   
   
   
   
   
   

As you can see on the attached image, the submit input does not have any icon.
