When you do a syncExec, your original job should just be waiting for the |
work on the UI thread to be done. Once syncExec returns, you should be
back on the original worker thread. Assuming you are not a UIJob, this
should not be the UI thread. You can store the data from the UI thread
in fields of the runnable handed to syncExec and then retrieve it from
there once syncExec has returned.
