Pannellum hot spots problem

You have to add an hotspot click handler to the pannellum definition: https://pannellum.org/documentation/reference/

I have added this to startup.js

 // add hotspot click handler.
 if (options.hotSpots) {
     var handler = this._onHotSpotClick.bind(this);
     for (var i = 0; i < options.hotSpots.length; i++) {
       var hs = options.hotSpots[i];
       hs.clickHandlerArgs = qx.lang.Object.clone(hs);
       hs.clickHandlerFunc = handler;
    }
 }

and

/**
 * Click handler for the hotspots.
 */
this._onHotSpotClick = function (e, hotspot) {
   this.fireWidgetEvent("hotspot", hotspot);
}

It will fire the “hotspot” event in the WidgetEvent handler. The e.Data dynamic object will be the full hotspot object. In C# the handler looks like this:

 private void Pannellum1_WidgetEvent(object sender, WidgetEventArgs e)
 {
    if (e.Type == "hotspot")
       AlertBox.Show(e.Data.text); // e.Data is dynamic and has all the hotspot fields.
 }

See attached modified sample extension.
