[flexcoders] Re: Two questions: Nested applications styles colllisions, flashvars injection
For anyone interested, I was able to get this to work normally when
building or with a loader passing flashvars:
package
{
import flash.display.Loader;
import mx.core.Application;
public class MyApplication extends Application
{
public function MyApplication()
{
super();
}
override public function get parameters():Object
{
if(systemManager.document.parent.parent is Loader)
return
systemManager.document.parent.parent.loaderInfo.parameters;
else
return super.parameters;
}
}
}

The _firstTime var declaration was dropped out of the code.
it's:
private static var _firstTime:Boolean = true;
Actually, the reason I used the first time is quite weird, if I set
the dispatchEventHook to null after getting the first preinitialize
event, it keeps calling it...
However, if I set it to ther fucntion it will call the other function.

Hi Alex,
thanks for your reply.
I guess you're right about the styles, since we use modal window to
open the loaded swf, we simply unloaded the main app styles before
loading the 2nd app.
Then, when the user is done with the loaded swf, we called it's
deactivate() method which unloads its styles and the main app reloads
its styles.
About the flashvars, I made it work, in a very hacky way, but I can't
think of anything else.
Basically, the solution is to catch the right moment to inject data to
the application.parameters, which is between when the application gets
a copy of the SystemManager.parameters and the tyime when the
application dispatces a preinitialize event, which is the time for
the app to start kicking.
The only way I found to catch this moment was to use the event
UIComponent.dispatchEventHook and check for the first preinitialize
event.
I had 2 problems with that:
1. I use actionscript only application for the wrapper, otherwise it
will make no sense to use a wrapper - that can be solved by copying
the mx_internal to access the UIComponent.dispatchEventHook and using
ApplicationDomain.getDefinition()
2. The UIComponent class definition is only avialable through
ApplicationDomain.getDefinition() at the SystemManager 2nd frame
So at first, I thought I could simply add an event listener to the
enterFrame, but then I found out, that the enterFrame is always
dispatched after the frameScript function, which in some cases can be
too late, because the application can get initialized and disapcth the
preinitialize before the first enterFrame event for frame 2 is
dispacthed.
So, to overcome these timing issues I had to override the call to the
SystemManager.docFrameHandler, by passing my own frameScript function
where I first acquire the UICompoennt class definition to use its
dispatch hook, and only then call the SystemManager.docFrameHandler
manually
Enough bubbling, here is the code, it's hacky, I'm aware of the risk
of using the mx_internal, but currently it works, so here it is:
package {
import flash.display.Loader;
import flash.display.MovieClip;
import flash.display.StageAlign;
import flash.display.StageScaleMode;
import flash.events.Event;
import flash.net.URLRequest;
import mx.managers.SystemManager; SystemManager;
import mx.core.mx_internal;
import mx.core.EventPriority;

private var _systemManager:MovieClip;

use namespace mx_internal;

{
stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;
_loader.contentLoaderInfo.addEventListener(Event.INIT,
loaderCompleteHandler, false, EventPriority.DEFAULT_HANDLER);
_loader.load(new URLRequest(Loadee.swf));
this.addChild(_loader);

Since you own both SWFs, I'd simply have a handshake between the loader

have it query the loading Apps loaderInfo.parameters.
