I'm using the Dia diagram editor to create an UML for a project, and I want to add a class into a package. This can be easily done when the class is created, then the class and the package are bound and the class can't be moved outside the package.
But I have designed many of my classes outside of a package and nom I want to add them in a package, and I can't figure out how to add a pre-existing class to a package.
Am I missing something ? Any ideas ?
