.. function:: doEvents
Syntax:
``h.doEvents()``
Description:
Deal with any pending events in the middle of a computation.
This also causes any previous flushes to make their effect felt on
the screen.
Faster than :func:`doNotify` since field editors are not updated.
.. function:: doNotify
Syntax:
``h.doNotify()``
Description:
All panels are updated so field editors show current values.
This is slower than :func:`doEvents` which does not check the field editors.
