- ## Method Details

  - ### handleQuitRequestWith

    void handleQuitRequestWith(QuitEvent e, QuitResponse response)
    Invoked when the application is asked to quit.

    Implementors must call either `QuitResponse.cancelQuit()`, `QuitResponse.performQuit()`, or ensure the application terminates. The process (or log-out) requesting this app to quit will be blocked until the `QuitResponse` is handled. Apps that require complex UI to shutdown may call the `QuitResponse` from any thread. Your app may be asked to quit multiple times before you have responded to the initial request. This handler is called each time a quit is requested, and the same `QuitResponse` object is passed until it is handled. Once used, the `QuitResponse` cannot be used again to change the decision.

    Parameters:
      `e` - the request to quit this application
      `response` - the one-shot response object used to cancel or proceed with the quit action
