[Qt-interest] return to command line but the GUI is still alive

[KC Jones]

I have not been paying too much attention to this thread, but I am doing
something vaguely similar and taking an entirely different approach.

My app is derived from QtSingleApplication and it accepts 'commands' from
the command line, from drop events on the Mac dock, or any other context
where a 2nd instance of the app can be launched.  QtSingleApplication routes
the command line arguments to the running instance via a message() method.

The class is not without a few cross platform issues, but for the most part
it works well on Win/Mac/linux.  Not sure what its availability is these
days.  We have a full commercial license which gives/gave us access.
