actionscript 3 - as3 self preloaded (internal) in Document Class -

-

i've googled lot , couldn't find except timeline based pre loaders or external pre loaders (loading external swfs).

i'm looking document class preloaded has library symbols exported first frame.

please advise.

i have private variables inside document class referring exported clips.

public var menu:menu; public var brand:movieclip; public var container:movieclip; public var background:background; public var intro:intro; public var language:language;

plus lots of clips exported flash on frame 1, instance combobox, (screenshot below)

enter image description here

you need use root.loaderinfo's bytestotal , bytesloaded properties.

when equal eachother, you've loaded 100% of swf , can manage should happen next accordingly.

sample:

package {      import flash.display.sprite;     import flash.events.event;       /**      * document class.      */     public class document extends sprite     {          // constructor.         public function document()         {             addeventlistener(event.enter_frame, _loadstatus);         }           // manage current status of preloader.         private function _loadstatus(e:event):void         {             if(loadpercent >= 1)             {                 removeeventlistener(event.enter_frame, _loadstatus);                  beginapplication();             }         }           // load complete, being application here.         protected function beginapplication():void         {             trace("loaded.");         }           // returns number representing current application load percentage.         protected function loadpercent():number         {             return root.loaderinfo.bytesloaded / root.loaderinfo.bytestotal;         }      }  }

i must note exporting library symbols on first frame bad idea - need make sure aren't exported on first frame.

bonus: having above class base class of actual document class makes tidy application entry point (where begin coding application):

public class mydocument extends document {      override protected function beginapplication():void     {         // application has loaded.         // initialize code here.         //         //     }  }

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
