Re: [Flashcoders] Help with listener for custom class (AS3)
Hi Dane,
Here are some thoughts for you to try. First off since you are not
actually working with a display object you don't need this class to extend
sprite. The easiest way to give the class the ability to send out events
is to have it extend EventDispatcher and then you can have it dispatch
events as required... here is you sample pared down a bit, just dealing
with xml
package {
import flash.events.*;
import flash.net.*;
public class fileImports extends EventDispatcher {
public var newStyleSheet:StyleSheet = new StyleSheet();
public var newXML:XML = new XML();
public function fileImports(xmlFile:String):void {
var xmlToLoad:URLRequest=new URLRequest(xmlFile);
var xmlLoader:URLLoader = new URLLoader;
xmlLoader.load(xmlToLoad);
//event listeners
xmlLoader.addEventListener(Event.COMPLETE,xmlLoaded);
}
public function xmlLoaded(event:Event):void {
newXML = XML(event.target.data);
dispatchEvent(new Event(Event.COMPLETE));
}
}
}
then in the movie calling the class
var tFile = new fileImports("data/xml/presenter1.xml");
tFile.addEventListener(Event.COMPLETE, xmlDone);
function xmlDone(e:Event){
trace("done");
}
hth,
Rob

But if I put a trace on newXML in the class, it shows the content of my

I have gotten this to work on other projects because I haven't tried to
use
the data immediately - so the data has time to "process" before it's put
into a text field, etc.
I appreciate any help I can get on this. Thanks!

Re: [Flashcoders] Help with listener for custom class (AS3)
>From your cssLoaded and xmlLoaded methods, dispatch an event each,
announcing the completion of load.
eg
public function xmlLoaded(event:Event):void {
newXML = XML(event.target.data);
dispatchEvent(new Event("xmlLoaded"));
}
And on the timeline, you can add a listener to that event by doing this:
var fileForThis:fileImports = new
fileImports("courseInfo.xml","styles.css");
fileForThis.addEventListener("xmlLoaded", onXMLLoad);
function onXMLLoad()
{
// xml loaded now
}
Of course thats not the best way to code ( you could create a custom event
object to pass more data etc, ) but the above should get you started.
Btw, your 'fileImports' class doesnt seem to be a UI class, so you dont have
to extend it from Sprite. Just extend EventDispatcher class.

[Flashcoders] Help with listener for custom class (AS3)
Greetings All,
I'm trying to do more and more of my projects with external classes and,
along with that, creating classes for routines that I regularly do. I have a
class that reads an XML file and CSS file once it's called. It has worked
fine for the first few projects I used it in. With my recent project, it's
not wanted to behave. The code for the class is as follows:
package {
import flash.display.Sprite;
import flash.text.StyleSheet;
import flash.events.*;
import flash.net.*;
public class fileImports extends Sprite {
public var newStyleSheet:StyleSheet = new StyleSheet();
public var newXML:XML = new XML();
public function fileImports(xmlFile:String, cssFile:String):void {
//load css file
var cssToLoad:URLRequest=new URLRequest(cssFile);
var cssLoader:URLLoader = new URLLoader;
cssLoader.load(cssToLoad);
//load xml file
var xmlToLoad:URLRequest=new URLRequest(xmlFile);
var xmlLoader:URLLoader = new URLLoader;;
xmlLoader.load(xmlToLoad);
//event listeners
xmlLoader.addEventListener(Event.COMPLETE,xmlLoaded);
cssLoader.addEventListener(Event.COMPLETE, cssLoaded);
}
public function cssLoaded(event:Event):void {
newStyleSheet.parseCSS(event.target.data);
}
public function xmlLoaded(event:Event):void {
newXML = XML(event.target.data);
}
}
}
I am creating an instance on my main timeline with this:
var fileForThis:fileImports = new
fileImports("courseInfo.xml","styles.css");
I am trying to use the data that is coming in with the XML file to populate
some combo boxes. My problem is I don't know how to "listen" to the class
from the main timeline to find out if the class is finished processing the
XML. Right now if I try to use "fileForThis.newXML" I get a value of null.
But if I put a trace on newXML in the class, it shows the content of my XML
file.
I have gotten this to work on other projects because I haven't tried to use
the data immediately - so the data has time to "process" before it's put
into a text field, etc.
I appreciate any help I can get on this. Thanks!
