It's fairly straightforward.. at least it is if what I'm about to show you
is what you want to know. In your class file follow this basic structure.
You'll need to import mx.events.EventDispatcher and add the three functions
at the bottom to any class you wish to broadcast from.
import mx.events.EventDispatcher;
class SampleClass {
function SampleClass() {
//Register
mx.events.EventDispatcher.initialize(this);
}
public function someFunction():Void {
//Build an event object. Type is the name of the callback function
you'll use. (listener.onDragRelease)
var eventObject:Object = {target:this, type:'onDragRelease'};
//You can also add variables to pass into the event
eventObject.position = getDropPosition();
//Send it away!
dispatchEvent(eventObject);
}
/**
* dispatchEvent
*
* Used to dispatch events
*
*/
function dispatchEvent() {
}
function addEventListener() {
}
function removeEventListener() {
}
}
To listen to those events you just need to add a listener that is listening
for the event name you defined in the event object as type:
applicationListener = new Object;
applicationListener.onDragRelease= function(eventObj) {
//trace(":: onDragRelease Event Recieved!");
//trace(eventObj.position);
//Do something here with the data
}
var someObject:Object = {};
someObject.addEventListener("onDragRelease",applicationListener);
Hope that helps you.
