Wake QThread from Windows event

Question

I wanted to have a sleeping thread that will be waked when a specifc USB device is inserted (VID and PID matches the ones I am expecting). How may I connect QThreads to Windows native notifications and make this work?

Was it helpful?

Solution

You can use the QAbstractNativeEventFilter to make a subclass for your Windows event.

As for your thread, you could use QWakeCondition to wait for this event to happen.
