Can you add consts for all of these? Plus move them to constructed(), constructor should have only the Object() call.

Please change the signature of the Wrapper, so a source that was already removed will not be removed again.

"...time = %g"; no need to allocate extra strings just to print a double :)

Pls disconnect the handler explicitly when it's no longer needed.
