Check if keyboard and mouse are available with Qt

Question

Is it possible to check if a keyboard and a mouse are connected to the system with Qt or any other C++ alternative? in windows

Good question. I think it is not possible with Qt, hence you have to use your own platform dependent calls. Some information about this [for windows](http://stackoverflow.com/questions/7798242/keyboard-mouse-input-in-c) and [for Linux/X11](http://stackoverflow.com/questions/50182/linux-x11-input-library-without-creating-a-window) (well, not even sure you can get the availability information easily with platform specific code...) — Boris Dalstein, Jul 15 '13 at 22:42
Still with those answers you need to click or press a key... — Alireza Soori, Jul 16 '13 at 07:42
Take a look at WMI programming here: http://msdn.microsoft.com/en-us/library/windows/desktop/aa394582(v=vs.85).aspx and then this class may be used to get the available keyboards: http://msdn.microsoft.com/en-us/library/windows/desktop/aa394582(v=vs.85).aspx There's probably something similar for mouse too. Do you need to do this on other platforms as well? — TheDarkKnight, Jul 16 '13 at 08:20

I think Qt in embedded Linux can detect the plug and unplug of an USB Mouse and enable it when USB mouse is plugged in.
