Track multiple instances of a QApplication

  • Hi,
    I have an application which is used by multiple users. The application is located on a server.
    I want to achieve the scenario where if User A clicks a QPushButton, I want to warn User B with some message on his desktop.
    How can I track which users are using the application ? How to display on the right desktop / screen ?

    Kindly provide some ideas / advise.

    Thanks very much.

  • Normally, you would use something like a message bus system, with a publish/subscribe mechanism.
