GObjectsignal_emit

void
g_signal_emit (
  GObject* instance,
  guint signal_id,
  GQuark detail,
  ...
)

Emits a signal.

Note that g_signal_emit() resets the return value to the default if no handlers are connected, in contrast to g_signal_emitv().

`instance`	`GObject`
	The instance the signal is being emitted on.
	The data is owned by the caller of the function.
`signal_id`	`guint`
	The signal id.
`detail`	`GQuark`
	The detail.
`...`
	Parameters to be passed to the signal, followed by a location for the return value. If the return type of the signal is #G_TYPE_NONE, the return value location can be omitted.
