Question

what I’m trying to do is accessing

   snapText = scrollPane.source.textSnapshot;

from an external swf. I’ve tried:

  trace("-->: "+scrollPane.source.textSnapshot.getText(0, 1000));
  trace("-->: "+myLoader.content.textSnapshot.getText(0, 1000));
  trace("-->: "+mc.textSnapshot.getText(0, 1000));
  trace("-->: "+mc.getChildAt(0).textSnapshot.getText(0, 1000));
  trace("-->: "+mc.getChildByName(myLoader).textSnapshot.getText(0, 1000) );
  trace("-->: "+scrollPane.content.textSnapshot.getText(0, 100));

all of which were fruitless. BTW:

  mc.getChildAt(0).textSnapshot.getText(0, 1000)

throws the error:

  1119: Access of possibly undefined property textSnapshot through a reference with static type flash.display:DisplayObject.

although I know the method is there.

all of the above code is run in the function checkHandler:

 myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, checkHandler);

so the swf should have been completly loaded.
The text is also there, I’ve checked with an swf decompiler.
the movieclip with the loader is created like this

 scrollPane = MovieClip(root).scrollPaneOnStage;
 myLoader.load(new URLRequest("tmp1.swf"));
 mc.addChild(myLoader);
 scrollPane.source = mc;

thanks in advance!

UPDATE – still not resolved

I’m now accessing the swf as pointed out by HotN.

  function checkHandler(evt:Event):void {

         libMC  = evt.target.content as MovieClip;
         libMC.gotoAndStop(0); 
          trace(libMC.textSnapshot.getText(0, 100));
         snapText = libMC.textSnapshot;
        scrollPane.source = mc;
    }

This resulted at first in an error, because the loader in an as3 script cant load an as2 movie (ie. AVM1). so I created an AVM2 swf which led to the error: Error #2000: No active security context. As a solution I used a class from http://www.igorcosta.org/?p=231 to load the swf, but still cant access the textSnapshot:

  trace(libMC.textSnapshot.getText(0, 100));

doesnt return anything and doesnt throw an error!

BTW: while I could change the format of the swf, I cant really change the file itself since it’s automatically generated.

Answer 1

So this has taken me enterily too long, but I got it figured out.

      //... {

        loader = new Loader();  
        loader.contentLoaderInfo.addEventListener(Event.COMPLETE, checkHandler);
        loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onError);
        var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain); 
        context.checkPolicyFile = false;
        loader.load(new URLRequest("tmp1.swf"), context);


      //..... }

      function checkHandler(evt:Event):void {

        loader.contentLoaderInfo.removeEventListener(Event.COMPLETE,checkHandler);

        libMC  = loader.content as MovieClip;

                    //works now!
            libMC.textSnapshot.getText(100, 200);

        scrollPane.source = libMC;


    }

so the trick was using the standard loader function like suggested so many times. however flash somehow messes up the security/sandbox settings on my local pc, which resulted in a Error #2000: No active security context. however it still worked fine when uploaded to a remote server, which is strange. you can set the local playback settings to “access local files only” under File > Publish Settings, but that didnt help at all in my case…
