Bound event object

gistfile1.js

var bound = goog.events.listen(src, type, function);

  // should dispatch event of type on provided targets (or else the src)
bound.fire([optional_targets]);

  // will call unbind the event
bound.unlisten();

  // can do things like:
var bound = goog.events.listen(src, type, function).fire();
  // so you can run a function

  // bound object should have fire, unlisted and the id available and look something like:
{
  type: [types],
  id: id_returned_by_goog_events_listen,
  src: the_source,
  fn: the function,
  capture: true_false,
  handler: context_for_fn,
  fire: function(opt_targets) {
    goog.array.forEach(types, function(type) {
      var target = this.src;
      if (opt_targets)
        target = opt_targets;
      if (!goog.isArray(opt_targets))
        target = [opt_targets];
      goog.array.forEach(target, function(src) {
        src.dispatchEvent(type);
      });
    };
  },
  unlisten: function() {
    goog.events.unlistenByKey(this.id);
  }
}
