[kepler-dev] Can I use Ptolemy actors in Kepler?

Hi Tony,

If you find a Ptolemy actor useful, just remember its class name (e.g. 
ptolemy.actor.lib.Ramp). In Kepler, "Tools/Instantiate Component" menu 
allows you to type in the class name, which will put an actor instance on 
your canvas just as dragging one from the actor tree.

The ptolemy jar is stored in the kepler.jar, so you have access to any 
Ptolemy actors and directors.

If you want to use a director not in Kepler tree, you have to use the
"Tools/Instantiate Attribute" menu. I use it to get a DDF director 
frequently (class ptolemy.domains.ddf.kernel.DDFDirector).

I suppose, you can create a kar file for any ptolemy actor just as for 
kepler actors, if you want to add some of them into the Kepler actor tree.

Best regards
