Tell if PC comes out of standby using Qt

Question

Is there a cross platform way, using Qt, to tell if a computer has come out of standby or hibernation.

I need to be able to detect when the computer has come out of standby in order to reset/continue a process. In this case it is a connection to a GPS via serial port.

Based on the discussion at http://comments.gmane.org/gmane.comp.lib.qt.general/39649 it seems that there is no reliable cross-platform way of doing this. The linked discussion provides some instructions on how to do this on windows and mac by listening to platform signaling.
