gdk:display-notify-startup-complete (display startup)

display -- a gdk:display object
startup -- a string with a startup notification identifier, for which notification process should be completed

Indicates to the GUI environment that the application has finished loading, using a given identifier. GTK will call this function automatically for gtk:window widgets with a custom startup notification identifier unless the gtk:window-set-auto-startup-notification function is called to disable that feature.
