AppLaunchContext.connectLaunchFailed

gio app_launch_context AppLaunchContext

Connect to LaunchFailed signal.

The #GAppLaunchContext::launch-failed signal is emitted when a #GAppInfo 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.
