To give it a little test-run, I’ve created a little gadget for hyves, which does nothing more than display a flash-animation while showing the thumbnails of my 10 last active friends over it. Just a little test to see if I understand the concept of creating a gadget.

So, an OpenSocial swf gadget sort of consists of 3 layers… at least, those are the ones I’m interested in. Swf <–> javascript <–> OpenSocial. In the Swf you use the ExternalInterface to communicate with Javascript, and Javascript makes the calls to OpenSocial. Retreiving data from a javascript is of course a piece of cake. The problem I ran into was when asynchronous calls came in play. For some reason the javascript couldn’t communicate the data back to my Swf, whatever I did… after a bit of digging, it turned out the problem was that, since my Swf gadget is hosted on my own domain instead of on the Hyves domain, I needed to add:

1
2

Security.allowDomain("*");
Security.allowInsecureDomain("*");

After that, things worked like a charm :)

AS3 ExternalInterface code:

import flash.external.ExternalInterface;
 
ExternalInterface.addCallback("loadDataResponse", loadDataResponse);
var r:Object = ExternalInterface.call("loadData");
 
public function loadDataResponse(xmlString:String):void {
	var myxml:XML = new XML(xmlString);
	// Do whatever you want with the xml
}

So, why this website?

Firstly, I haven’t got anything else to put up here, the last 2 years my website consisted of nothing more than a (in my ‘coding’ eyes) pretty okay attempt at typography and design… or, more clearly said… the word ‘Develicious’ and a half eaten strawberry (see exhibit A).

Secondly, and probably the more important and valid reason, during my programming I sometimes run into problems, but I always manage to find the solution. Sometimes fast, after using my good friend google and finding what I need instantly… sometimes it takes me a few hours, when I have to start digging myself because I can’t find anything on google. So the idea is to save other people the trouble of doing the same digging as me :)
