I'm researching the possibility of building a plugin that would take the
Call Hierarchy tree, add a new popup menu to generate GraphViz dot
source -- not sure of the destination, clipboard, .png in a browser or
somesuch -- right now I'm just trying to find out about where and how
I'd hook in to do this. I'd want/need access to the currently displayed
call hierarchy tree.
Is there a ready-made JDT extension point for something like this? I'm
guessing not since browsing through jdt.jar shows CallHierarchy stuffs
only in the internal package. Would I need to modify the actual source
to do this, rebuild a custom .jar?

I'm familiar with CopyCallHierarchyAction, it's what I based my current
class on (GraphCallHierarchyAction) -- all I need is the plug-in stuffs
to hook into CallHierarchyViewPart without actually modifying its code
to add my popupMenu. My current hack simply modifies the source in
CallHierarchyViewPart, but apparently, I should be able to plug-in to it
externally, but I don't know how yet.

Oh, that's no problem. I'm primarily using it on a current gig to help
myself out, and my hacking approach is fine for that, but I would like
to know how to do it as a pure plug-in, as that might make it more
accessible to others.
