JFace dependancies [message #447745]

Hello,

I would like to evolve my SWT application with using the Model- and
Viewer-Classes of JFace. Now, as far as I know in order to use JFace I need to
put runtime.jar and platform.jar on the classpath too. I do not understand why,
since the Model-Classes should work without it, or am I wrong?

Regards,
Ben

I think you need runtime.jar and osgi.jar but not platform.jar.

JFace depends on some classes in the runtime packages. From what I've
heard, the Platform UI team (they're responsible for JFace, not the SWT
team) isn't explicitly designing JFace for standalone SWT app use. I think
they are not trying to make things very tightly coupled to Eclipse, but at
the same time they aren't practicing any specific discipline to assure that
there is zero coupling. So there are instances where the JFace classes
require some runtime classes (which in turn require some osgi classes). I
believe the Platform UI team is debating whether to devote time to removing
these dependencies from JFace.

Thanks Chris, that bug report is exactly what I was talking about.
Too bad that activity froze some months ago :/

A few months ago I've implemented a few stubs that eliminated the
dependencies on runtime.jar, platform.jar and OSGI.jar without problems.
Let me know if you are interested...
