Need to keep track of the cursor offset in a TextEditor plugin [message #262439]

Dear Distinguished Colleagues:

I need to be able to keep track of the cursor offset; i.e. every time
the user moves a cursor, I need to be able to notify a listener of the
new character offset that the cursor is pointing at. It doesn't need to
be in real time, a small delay is ok so I can do it using a thread.

Any thoughts ?

Oleg

have a look at IPostSelectionProvider - the ISelectionProvider returned
from ITextEditor.getSelectionProvider may implement it.

I think it is different... Selection changed event is not triggered, not
even for selecting a region of text...

Not sure what you mean - yes, you should get SelectionChangedEvents once
you register as listener!
