Project and JavaProject - Navigator & Pkg Explorer view [message #56134]

Hi,

I am trying to create a view to respond to a Project selection in the
Navigator and Pkg explorer view. And have been having trouble in making it
work for both the views. The selection in the Pkg Explorer is IJavaProject
and the selection in the Navigator is an IProject and they both have nothing
in common, meaning no base class to link them.

Why didn't the JavaProject implement the IProject ? was there a good reason
behind that ?

For the navigator view, I used JavaCore.create((IResource) selObject);
to get the JavaElement and from that got the JavaProject. But when I needed
to get the location of the project, I could only find that information in
the IProjectDescription... As far as I see, JavaProject is project.

It would be nice if some one could shed light on why JavaProject was not
implementing the IProject. I am sure there is a good reason, and it would be
nice to see why, since it doesn't make sense for me.

thanks,
-Anou

An IProject with its included resources can serve as underlying resource
for more than one kind of project / nature.

In case of
resource: res.getProject().getLocation()
Java element: je.getJavaProject().getProject() [ and then see above
line]

You'd better ask on eclipse.tools.jdt.

Thanks Daniel for the response.

I did workaround getting the project out of the JavaProject and getting the
description out of it. But it felt wrong, I understand that the IProject is
an underlying resource and it should be the base class for the different
kinds of projects. Why is JavaProject not a Project ? It is a project with
additional features that make it a Java project, so it is a project at its
low level, I don't think it is wrong to consider it as a project.

I will repost it in the jdt newsgroup.

regards,
-Anou
