External Class

[Zaqoa]

Add some custom class loading to the mag...

first add some node-type to the xml called class
 <class src='name.swf' name=dir.classname' param='param1,param2,paramX' />

change the page.as objects:
INTERNAL_ELEMENTS:Array = new Array("area", "img", "nav", "snd", "txt", "class");
INTERNAL_CLASSES:Array = new Array(Area, Image, Navigation, Audio, Text, ExternalClass);

add some lines to the megazine parser
var classID:String = (pageData[id] as XML).children()[0].toXMLString();
if (StringUtils.contains(classID, "<class"))
{
   var param:Array = Delimiter.parseComma((pageData[id] as XML).children()[0].@param.toXMLString());
   dataProvider[param[0]] = param;
}

The Delimiter class separates the param-attribute into an array.
The dataProvider is a simple array, as a private property from the megazine class

define another AbstractElement called ExternalClass
load the src from the class-node
if (xml.@name.toString() != "") { classname = xml.@name.toString(); }
classLoader.load(url, false);

and init the class after loading.
classLoader.removeEventListener(ClassLoader.CLASS_LOADED, onEvent);
classItem = classLoader.getClass(classname);
var id:int = page.getNumber(even) + 1;
var obj:* = new classItem();
obj.init(mz.dataProvider[id], false);
obj.setCallback(mz.callback);

Note that every external class loading container implements an interface called IPage
function init(data:Array, logstatus:Boolean):void;
function getData():Array;
function setCallback(callback:Function):void;   

that's it...

the forum is not the best for publishing code...
if you interested, i send you the customized code snippets...

I don't really understand what that does, could you explain? It looks a bit like a roundabout way to a functionality similar to what's possible using external elements (e.g. vid).

The Snippet allow you to load custom classes with custom properties and give you the possibility to call other functions from these classes with the callback function.

e.g. you have a time-controlled book, where at specific points some pages are enabled and disabled ... and the pages call an external flash layer with some video stuff ...
