[Qt-interest] Sending window messages between Qt processes

[Bob Hood]

Thanks, David.

However, a Windows-based D-Bus solution does not come OOTB with Qt, so
the answer would have to be "no" -- in fact, if it did, I wouldn't be
using QSharedMemory :).  I need something that comes with, and builds
directly from, Qt.  Sending user-defined messages to the main
GUI-processing loop would, I think, serve my needs rather nicely, if I
knew it could be done, and how to do it.
