Hi,
I making custom Event class, I did it, it works but have some problems.
I make to show some photos in the swf
I import my class album, and this class, call another class loadImages. loadImages, put photos in Scene, I want to make when an image load, to dispatchEvent, and album class to get the event. I make listeners to get the event, but they didn’t.
Here is the all. http://theflashblog-bg.com/resources/Event.zip
here is code in the main timeline
[AS]import classes.album;
var MyPhotoAlbum:album = new album();
MyPhotoAlbum.loadXML(“photoflow.xml”);
MyPhotoAlbum.name =“myALb”;
addChild(MyPhotoAlbum);[/AS]
my event class
[AS]package classes.events_v3 {
import flash.events.*;
public class flowEvent extends Event {
public static const PLC:String = "photo load complited";
public function flowEvent() {
super(type, true);
}
}
}[/AS]

so u can see for now I’m getting the event with this lines in loadImages.as
[AS]var ff:album = new album();
addEventListener(flowEvent.PLC, ff.photoHaveBeenLoad);
dispatchEvent(new Event(flowEvent.PLC));[/AS]
but I want to add dispatchEvent in albun like so
[AS]
temp.name = “photo”+String(i)+"_mc";
//addEventListener(flowEvent.PLC, photoHaveBeenLoad);
addChild(temp);[/AS]
but if I write addEventListener, didn’t get the event. What to do?
