Re: [mdt-uml2tools.dev] Modifying class diagram editor popup menus
|
Hello,
Sure, it will work. As a side effect though, it will add this popup
menu not only to all elements of all Uml2Tools diagrams (say, to
UseCase diagram actors or to Activity' pins) but also to ANY GMF-based
diagram that will be available in the same workspace. Say, ships,
routes and harbors at the GMF standard sample Taipan will be also
affected.
May be its not a problem, just wanted to make a note :)
Regards,
Michael
