And if loose coupling is not a key issue for you, you can simply access
public members in the loaded swf using the "content" property of
SWFLoader. If you are loading appliations, use SWFLoader, not Image.
Access top level application members using Application.application.
You will need to listen for the complete event of the loader and the
APPLICATION_COMPLETE event of the loaded app before you can access
properties via the "content" property:
<mx:SWFLoader id="ldMain" progress="showProgress(event)"
width="100%" height="100%"
complete="onCompleteAppLoader(event)"/>
/** runs when SWFLoader content has all downloaded */
private function onCompleteAppLoader(oEvent:Event):void
{
var smAppLoaded:SystemManager =
SystemManager(oEvent.target.content);
smAppLoaded.addEventListener(FlexEvent.APPLICATION_COMPLETE,
onCurrentApplicationComplete)
//vbMask.visible = false;
}//onCompleteAppLoader
/** runs when the app loaded in the SWFLoader has completed
initialization
* and is ready for any access (applicationComplete event)
*/
private function onCurrentApplicationComplete(oEvent:Event):void
{
_appLoaded = Application(oEvent.target.application);
_sAppLoadedUrl = _appLoaded.url
var iPosLastPathDelimiter:int = _sAppLoadedUrl.lastIndexOf("\\");
if (iPosLastPathDelimiter == -1) {
iPosLastPathDelimiter = _sAppLoadedUrl.lastIndexOf("/");
}
_sAppLoadedName =
_sAppLoadedUrl.substring(iPosLastPathDelimiter+1,_sAppLoadedUrl.lastInde
xOf("."));
}//onCurrentApplicationComplete
/** */
public function showProgress(oEvent:Event):void
{
var sBytesLoaded:String = oEvent.target.bytesLoaded;
var sBytesTotal:String = oEvent.target.bytesTotal;
_nLoadProgress = (sBytesLoaded/sBytesTotal) * 100;
lbLoading.alpha = 1/_nLoadProgress * 10;
if (_nLoadProgress == 100) {
lbLoading.visible = false;
lbLoading.alpha = 1;
}
} //showProgress

Subject: Re: [flexcoders] Communication of data between parent and child
movie.
Using the inbuilt event dispatching system is your best bet.
That way you can have your parent(s) and child(s) loosely coupled.
There are particular design patterns that also deal with this issue.
Personally i like the combination of DataBinding,
ModelLocator(Singleton) and Commands, ala Cairngorm :)

Hi everyone,
Currently I have to write a Flex application that holds other swf
application within it (I will have a skeleton swf movie with menu on
the left hand side and when a menu item is clicked, the corresponding
sub application is loaded on the right hand side, onto an Image
control).
The problem is that how can we propagate information from the child
movie to the parent movie and vice versa? Say the sub movie does the
login procedure and return the authentication information, how can I
pass this information to the parent movie so that it can be used to
control the access given to this particular user?
