I only wanted to point the solution used by the QtSingleApplication.
I am sure they opted for the most efficient solution when they implemented that class.

There are many methods, I can't argue with that. But some of them are almost "theoretical". There's no winning in implementing them.
On Unix they use: "On X11 systems the implementation uses X atoms to communicate through the selection mechanism.".

We didn't.

I'm using Qt 4.3.3 and the "QtSingleApplication" class is not listed in the Assistant.

What version was/is it in?
