gtk: how to use g_signal_emit properly?

Happy new year everybody,

I would like to understand how to use g_signal_emit properly. I have a gtk_event_box and I want to cause it to emit a enter_notify_event when I want it to. What I tried (R GTK binding code):

on_enter = function(...){TRUE}

w = gtkWindow()
ebx = gtkEventBox()
gtkContainerAdd(w, ebx)
gtkWidgetAddEvents(ebx, GdkEventMask["enter-notify-mask"])
gSignalConnect(ebx, "enter-notify-event", on_enter)

What arguments to I have to pass to g_signal_emit now? My naive approach does not work..

gSignalEmit(ebx, "enter-notify-event")

Thanks in advance

Following @gpoo's comment I post my solution as a separate answer here. The answer is simple: You just have to modify the last function call to: 

gSignalEmit(ebx, "enter-notify-event", NULL)
