Double Click event handler for Tree View

Hi,

So, according to the Object Model Viewer in ESTK...TreeView does not have an onDoubleClick event.  I'm wondering if this can be added in any way?  I've looked into the controlObj.addEventListener() functionality but it's unclear how to actually add the double click listener.  It says that both click and double click are the same event name and you differentiate between them by specifying a detail level, 1 being single click, 2 being double click.

          controlObj.addEventListener("click (detail = 2)", func);

It may be that if an element doesn't implement the event handler then it can never be added.  I did notice that I could add a "click" event handler to the TreeView which is not supposed to be implemented on the TreeView. 

Any thoughts on how to use TreeView.addEventListener to defined the double click event?  How would I send it the different "detail" value? 

Thanks!
