If you need to call the sub-SwF method, you can convert the loadswf application to an object, and then call the method in the sub-SWF. Otherwise, the method cannot be found.

 VaRLoadswf: systemmanager=Systemmanager (myloader. content );

(Loadswf. Application as object). Test ();

Later, I found that the above Code is still risky. If the SWF file to be loaded is large, the value of application in item_loadswf may be null.

Below is a piece of code I added.

Supplemental code Private VaR _ Loadswf: systemmanager;
Private VaR Content: image;
Private Function Onloadcompleted (Event: Event ): Void
{
_ Loadswf = systemmanager (content. content);
_ loadswf. addeventlistener (flexevent. application_complete, swfready);

function swfready (Event: flexevent): void
{< br> _ loadswf. removeeventlistener (flexevent. application_complete, swfready);
(_ loadswf. application as object ). test ();
}< BR >}
