title: How do I determine open/closed state of a dijit dropdownbutton?
body: <p>I'm using a dijit DropDownButton with an application I'm developing. As you know, if you click on the button once, a menu appears. Click again and it disappears. I can't seem to find this in the API documentation but is there a property I can read to tell me whether or not my DropDownButton is currently open or closed?</p>
  
  <p>I'm trying to use a dojo.connect listener on the DropDownButton's OnClick event in order to perform another task, but only if the DropDownButton is clicked "closed."</p>
  
  <p>THANK YOU!
