GObject.signal_stop_emission

function signal_stop_emission(instance: GObject.Object, signal_id: Number(guint), detail: GLib.Quark): void {
    // Gjs wrapper for g_signal_stop_emission()
}
  

Stops a signal's current emission.

This will prevent the default method from running, if the signal was GObject.SignalFlags.run_last and you connected normally (i.e. without the "after" flag).

Prints a warning if used on a signal which isn't being emitted.
