[news.eclipse.platform] Re: How to contribute popupMenu programmatically

[Paul Webster <pwebster@xxxxxxxxxx>]

It can't be done in a normal way, not to mention the fact that searching 
the IResource tree for a project to find files with 2 extensions can be 
an expensive operation, and you don't want the users to right click ... 
and wait while you scan the disk.

If it really is necessary, you could scan the IResource tree for the 
workspace in a Job, and add a persistent property to the IProjects that 
meet your criteria.  Then your action (via org.eclipse.ui.popupMenu or 
org.eclipse.ui.menus) could check for the property.
