[Qt-interest] Detecting operating system shutdown

[Bob Hood]

Yes, it did.  I sub-classed QApplication, overridding commitData(). 
When it is called, I tell my MainWindow to save it's settings (the same
as it does on a normal application exit).  I tested this with a shutdown
of my Vista64, and pending settings data was correctly written to disc
before the machine switched off.

Just what I needed.
