SWC and Library Path

Hello, in Flash CS4 I created two FLA file.

In the First File:

  • I draw a shape;
  • I convert it to a MovieClip;
  • I link a MyClip class with a simple trace in the constructor;
  • I export the whole file as MyClip.SWC;

In the Second File:

  • I go to Edit > Preferences > ActionScript > ActionScript 3 settings and I add -in the Library Path- the file MyClip.SWC;
  • on the first frame of this swf I write var myClip:MyClip = new MyClip(); addChild(myClip);

I don’t know what I’m doing wrong but when I compile (export swf) the class gets loaded (I see the trace in the output window) BUT I can’t see the graphics associated to MyClip. It seems MyClip.SWC only contains the code of that clip.

What am I doing wrong?
Is it even possible what I’m trying to do?

Can you help me?
Thanks!
