[news.eclipse.platform] adding doubleclick listener

[Pradeep <pradeep.chandrasekaran@xxxxxxxxx>]

Hi all,
   Could anyone help out in how to add a doubleclick listener to a resource in the package explorer so that i can open a FormEditor on that event, which is similar to the action of opening the editor as we click the plugin.xml. 

Thanks in advance,
Pradeep kumar
