[e4-dev] Drop Adapters in Resource Viewers

[Serge Beauchamp <serge@xxxxxxxxxxxxx>]

Hi all,

With the e4 resource improvements effort, changes have been made to the 
way dropping resources is handled in the navigator view. 
The user can now choose to automatically create groups and linked 
resources simply by dragging files in the resource viewer (see a 
demonstration of this feature at 
http://www.youtube.com/watch?v=ej-diQ9ClV0).

Unfortunately, since those UI changes required code change in the 
org.eclipse.ui.ide plugin, and every resource navigator (the Package 
Explorer, Project Explorer, the CDT CView, etc...) use their own 
implementation that does not share the org.eclipse.ui.ide 
NavigatorDropAdapter.

Ideally, those views will be refactored into using all a common 
component that is full featured and easily maintainable.  Since only the 
org.eclipse.ui.ide plugin is part of the e4 resource plugin, I'm not 
sure what's the best way to go about that, or how to coordinate such an 
effort.

Also I have been told that maybe the "Modelled UI" may have some idea on 
the way to do with this general feature.

Any comments would be appreciated, thanks,
