title: jQuery UI event and ui object properties
body: <p>In the jQuery UI framework for Interactions you can do custom functions and they take two parameters 'event' and 'ui'.  I know it has to be obvious somewhere but I cannot find out what methods and properties are available on those two parameters.</p>
  
  <p>Does someone know what methods and properties are available on those parameters or where I can I find them?</p>
