[Pydev-code] Re: PyDev WorkingCopyManager?

[Aleks T. <a...@to...>]

I have not worked on pydev in a while, but I do not recall ever 
touching the workingCopy class. We are not derived from the same 
code base. Are you looking for a way to detect the name of the 
current function underneath the cursor? We do something like this 
to show hyperlinks over function names:

IDocument doc = 
pyEdit.getDocumentProvider().getDocument(pyEdit.getEditorInput());
ITextSelection selection = (ITextSelection) 
pyEdit.getSelectionProvider().getSelection();
	
Location loc = Location.offsetToLocation(doc, selection.getOffset());
AbstractNode node = 
ModelUtils.getElement(pyEdit.getPythonModel(), loc,
AbstractNode.PROP_CLICKABLE);

Node should then contain the element you are hovering over.

This all might be obsolete, but that's the way it looked last 
time I looked at it.
