  • Method Details

    • run

      void run(String startupNotifyId)

      The Gio.AppLaunchContext::launch-failed signal is emitted when a AppInfo launch fails. The startup notification id is provided, so that the launcher can cancel the startup notification.

      Because a launch operation may involve spawning multiple instances of the target application, you should expect this signal to be emitted multiple times, one for each spawned instance.
