title: ExtJS Button Style Toolbar
body: <p>I was wondering if it is possible to put a button into a panel's toolbar but have it retain the look of a button as if it was just in a plain panel.</p>
  
  <p>For example, i want the button to look like this:</p>
  
  <p><img src="https://i.stack.imgur.com/fHIWA.png" alt="Button Style"></p>
  
  <p>However, it looks like this:</p>
  
  <p><img src="https://i.stack.imgur.com/Lp8pr.png" alt="Toolbar Button"></p>
  
  <p>Thanks so much!</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Code to create toolbar:</p>
  
  <pre><code>xtype: 'toolbar',
          items:
          [
              {
                  xtype: 'button',
                  text: 'Select bounding box on map',
                  id: 'bbBoxButton',
                  icon: 'img/cross_cursor.gif',
                  listeners: {
                      click: function(){
                          polygonControl.activate();
                      }
                  }   
              }
          ]
  </code></pre>
  
  <p>Code to create regular button:</p>
  
  <pre><code>{xtype: 'button',    id: 'bboxButton', text: 'Select bounding box on map', icon: 'img/cross_cursor.gif', listeners: {click: function(){polygonControl.activate()}}}
  </code></pre>
  
  <p>I believe I have to use the cls config for the button, but i cannot seem to find the appropriate css class.</p>
