Virtual Method

GioAppLaunchContextget_startup_notify_id

Declaration [src]

char*
get_startup_notify_id (
  GAppLaunchContext* context,
  GAppInfo* info,
  GList* files
)

Description [src]

Initiates startup notification for the application and returns the XDG_ACTIVATION_TOKEN or DESKTOP_STARTUP_ID for the launched operation, if supported.

The returned token may be referred to equivalently as an ‘activation token’ (using Wayland terminology) or a ‘startup sequence ID’ (using X11 terminology). The two are interoperable.

Activation tokens are defined in the XDG Activation Protocol, and startup notification IDs are defined in the freedesktop.org Startup Notification Protocol.

Support for the XDG Activation Protocol was added in GLib 2.76. Since GLib 2.82 info and files can be NULL. If that’s not supported by the backend, the returned token will be NULL.
