RE: [Dynapi-Dev] TCanvas vs. DynLayer

Yes, Dynlayer and dyndocument use the same base class to inherit from.
dynobject contains all parent-child relations (adding,removing,deleting,
etc)

Also events are extending the dynobject, so dynlayer and dyndocument also
share that same extension (no differences between the code).. should make
developing things easier (having one object that contains the code, others
simply use it)

it looks like its working great (the release has been out for a while now,
haven't heard of big problems or found myself.. all Dynapi examples work
correctly with dynacore)
