I am currently attempting to customize the ResourceNavigator right now and
running into a lot of issues. Mainly these deal with the inconsistant use
(or non-use) of the IAdaptable interface to convert the Objects in the
TreeViewer into IResource objects. I use an object which implements
IAdaptable for the input to my TreeViewer. I also register an
IAdapterFactory with the IAdapterManager that can produce IResources from my
objects. Half of the time the eclipse code just does a instanceof or cast
to an IResource and the other half of the time it checks to see if its an
IAdaptable and tries to get the IResource via getAdapter. Its very
frustrating. For instance, right now I'm having to basically rewrite the
code for some of the ActionGroups, like GotoActionGroup, because its
fillContextMenu uses ResourceSelectionUtil. ResourceSelectionUtil has 2
main methods used for verifying that a selection is a set of IResource
objects. One of these methods checks for IAdaptable, and the other one
doesn't. Typically I would subclass this group and override the
fillContextMenu method, however, all of the Actions in the group are
declared private, and there are no getters/setters for them.
If you are looking for people to help in the process of making the
ResourceNavigator more easily customized by developers, I'd like to be
involved.
Thanks,
Bruce
