I've written an application recently using SWT. In one of its dialog box, I have a few widgets, one of which is Text, which is designed to support DND with other widgets.

In the Java code for our application I'm pretty sure there are lots of classes and methods which have public access but probably only need package level access. What I'd like to do is to tidy up our code on a package by package level, making only things that really need to visible outside each package public as this should simplify othe...
Hi all, does anybody have some ideas on how to achieve that? Or even a good documentation on how to do that?

Thanks for every suggestions! Ro...
