    Default Creating a timed menu in Main()

    Using Qt5 and QCoreApplication I want to create a timed menu that waits 15 seconds for a response, and if one is not received, moves on to the eventloop and the rest of the program. This program is ran completely from the console. I have tried using a timed while loop, however

    Qt Code:
    1. cin.readLine();
    To copy to clipboard, switch view to plain text mode 

    stops the loop and waits for a response.

    Any ideas on how to go about creating this?

    !!! get a timer, with a flag set. if user inputs something readline returns with flag set to entered.
    else, if timer passed with no input, then write dummy chars to get rid of readline.

    Setup a QSocketNotifier on stdin, connect to its signal and run the event loop (e.g. via QEventLoop). Together with a timer that will quit the loop after 15 seconds, you can set a mechanism appropriate for your task.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.
