Next to my previous blog post a SwF class that I usually use to load avm2 and share it with everyone.

After the SWF file is played, A video_is_over event will be sent. Because _ loader is used to send the event, the event must be captured in the capture phase (event Stream Mechanism of ActionScript 3 ). The following is a simple application:

// <Br/> // luxflashenvironment. as <br/> // the entry of application <br/> // written by leezhm, 7th Nov, 2009 <br/> // contact: Leezhm@126.com <br/> // last modified by leezhm on 7th Nov, 2009 <br/> // </P> <p> package SRCS <br/>{</P> <p> Import flash. display. sprite; <br/> Import flash. events. event; </P> <p> public class luxflashenvironment extends sprite <br/> {<br/> private VaR _ loadmedia: cload Media; </P> <p> Public Function luxflashenvironment () <br/>{< br/> If (stage) <br/>{< br/> initapplication (); <br/>}< br/> else <br/>{< br/> This. addeventlistener (event. added_to_stage, initapplication); <br/>}</P> <p> private function initapplication (EVT: event = NULL ): void <br/>{< br/> This. addeventlistener (cloadmedia. video_is_over, onvideoplayover, true); </P> <p> This. _ loadmedia = new cloadmedia ("Medi As // middle.swf ", this); <br/> This. _ loadmedia. loading (); <br/>}</P> <p> private function onvideoplayover (EVT: event = NULL ): void <br/>{< br/> If (null! = This. _ loadmedia) <br/>{< br/> This. _ loadmedia = NULL; <br/>}< br/>}

In cloadmedia class, we also implement the property currentmovieclip for converting the loaded SWF into a movieclip instance. With this property, we can operate the loaded external SWF file like movieclip.
