Hi Jukka,
thanks for the comment, regarding my part, cadtools are relatively old and
they were never upgraded to new shortcuts added by Ede on OJ: they were
basically a sort of "programming java test" for me.
Recently I started to work to a new version, removing the tools which
have no usage, porting some Kosmo ones and making more OJ shortcut
compatibly .
I would like to add the source to OJ repository and have in OJ Plus, as
separate plugin/toolbar
Porting Kosmo tools is not difficult, even for a newby like me. The problem
is the dependency to many classes, some of these classes might have
equivalence to OpenJUMP one, but it is quite difficult to find them.
Best regards
Peppe
