connectLaunchStarted

fun connectLaunchStarted(connectFlags: <Error class: unknown class> = ConnectFlags(0u), handler: (info: AppInfo, <Error class: unknown class>?) -> Unit): <Error class: unknown class>

The #GAppLaunchContext::launch-started signal is emitted when a #GAppInfo is about to be launched. If non-null the @platform_data is an GVariant dictionary mapping strings to variants (ie a{sv}), which contains additional, platform-specific data about this launch. On UNIX, at least the startup-notification-id keys will be present.

The value of the startup-notification-id key (type s) is a startup notification ID corresponding to the format from the startup-notification * specification. It allows tracking the progress of the launchee through startup.

It is guaranteed that this signal is followed by either a #GAppLaunchContext::launched or #GAppLaunchContext::launch-failed signal.
