   && (Parameters!T.length <  1 || (ParameterStorageClassTuple!T[0]  ==  ParameterStorageClass.none &&  is(Parameters!T[0]  ==  string)))

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.

Parameters

`callback`	signal callback delegate or function to connect `void callback(string startupNotifyId, gio.app_launch_context.AppLaunchContext appLaunchContext)` `startupNotifyId` the startup notification id for the failed launch (optional) `appLaunchContext` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
