[Dltk-dev] For use in a UI view, how to get the raw AST from the core?

[Gerald Rosenberg <gerald@xxxxxxxxxx>]

Wish to add a custom UI View that details/uses the raw AST as generated
through execution of the core
ISourceParser#parse.  By
raw, I mean the native AST generated by my script parser, before it is
processed into a standard DLTK TypeDeclaration tree.  I can add the
raw AST as a field to the root TypeDeclaration.  Now just need to
have some kind of event that the UI view can listen for to pick up the
TypeDeclaration tree whenever it changes.

I realize this appears similar to the content view, but that view appears
to be keyed to using ISourceModule (somehow) -- cannot seem to trace for
certain how it is getting a handle to the root
TypeDeclaration of the core
AST.

Looks like there is a

DLTKCore#addElementChangedListener.  Would this be the
correct DLTK-way of listening for AST parse updates?  If not, could
you please provide a suggestion about how best to do this.

Thanks,
Gerald
