First a warning.... not all buttons are connected to the system in the
same manner. If you lucky the platform exposes the button as an input
device mapped to a key.
Ok... now if you are lucky enough to have the power button for your
specific device mapped to some key, you can use XGrabKey from a process
inside the user session but without active keyboard focus (like a
homescreen running in the desktop.) This isn't a Qt mechanism but a low
level XLib call.
On a linux workstation run 'man XGrabKey' to learn all about it.
