ion-directives could broadcast gestures to controller

[gregaton]

Instead of only supporting touch/click events with a fixed behavior the directives could also support other gestures and broadcast them to the corresponding controller.

I said could because I'm not sure what potential drawbacks all those event listeners and broadcast messages could have.

To give a practical example, I am currently using the following directive to allow hold gestures for my tabs.

module.directive('ionTabControllerItem', ['$rootScope', '$ionicGesture', function($rootScope, $ionicGesture) {
  return {
    priority: -10,
    restrict: 'E',
    require: '^ionTabs',
    compile: function(element, attr, transclude) {
      return function link(scope, element, attrs, tabsCtrl) {
        $ionicGesture.on('hold', function(e) {
          $rootScope.$broadcast('tab.hold', scope.$index);
        }, element);
      };
    }
  };
}]);

Hi @gboxall,

Right now you are doing this the best way you can.

Starting in 0.9.26 and the nightly build, change ionTabControllerItem to ionTabNav in your case.

In the future, we may have declaratively created tabNav, so you could just do <ion-tab-nav ion-hold="action()">. Right now, your way is good.
