title: Adding double click handler for Ext.ux.gauge.Gauge
body: <p>The gauge widget in the ExtJS classic UX package is a great way to add a simple gauge to an application, however in my case I need to have a handler for when the gauge is double clicked.</p>
  <p>Typically this case a listener would be added shown in <a href="https://fiddle.sencha.com/#view/editor&amp;fiddle/37rk" rel="nofollow noreferrer">this fiddle</a>, however the widget doesn't support that event.</p>
  <p>Has anyone already come up with a solution for this? What would be the best approach - a custom plugin that gets added to the widget?</p>
  <p>I see that a plugin (chartitemevents) exists for adding support for these events to charts, but I was hoping to keep the simple configuration of the UX Gauge widget.</p>
