[Newbies] Beginners Digest, Vol 123, Issue 3

Wed Feb 22 18:52:06 UTC 2017

Please allow me to simplify my question. I need a basic answer.

One of the articles on Morphic says you can create composite morphs either
programatically, using addMorph, or using drag and drop from the Objects
menu of the morphic World. I have done the latter, because it is easier to
design my layout that way. Once that has been done, how do I address the
submorph from a browser? If I inspect my button submorph, for example, all
it will tell me about it is "a ScriptableButton<Button>(1364754)". I have
no idea how to access that object in order to do anything with it. This is
the crux of my questions.

Thank you

Tim Cuthbertson
