Hello, I don't know what's the best way to do it, but here are some ideas.
1. Use aboutToQuit and block it with a QEventLoop ? It might not be enough and might leave the application cover open on the multitask grid, making it look not responding. 2. Launch a script / program when quitting, that performs the async task.
