Function

GObjectsignal_newv

Declaration

guint
g_signal_newv (
  const gchar* signal_name,
  GType itype,
  GSignalFlags signal_flags,
  GClosure* class_closure,
  GSignalAccumulator accumulator,
  gpointer accu_data,
  GSignalCMarshaller c_marshaller,
  GType return_type,
  guint n_params,
  GType* param_types
)

Description

Creates a new signal. (This is usually done in the class initializer.)

See g_signal_new() for details on allowed signal names.

If c_marshaller is NULL, g_cclosure_marshal_generic() will be used as the marshaller for this signal.

Parameters

`signal_name`	`const gchar*`
	The name for the signal.
	The data is owned by the caller of the function.
	The value is a NUL terminated UTF-8 string.
`itype`	`GType`
	The type this signal pertains to. It will also pertain to types which are derived from this type.
`signal_flags`	`GSignalFlags`
	A combination of `GSignalFlags` specifying detail of when the default handler is to be invoked. You should at least specify `G_SIGNAL_RUN_FIRST` or `G_SIGNAL_RUN_LAST`.
`class_closure`	`GClosure`
	The closure to invoke on signal emission; may be `NULL`.
	The argument can be `NULL`.
	The data is owned by the caller of the function.
`accumulator`	`GSignalAccumulator`
	The accumulator for this signal; may be `NULL`.
	The argument can be `NULL`.
`accu_data`	`gpointer`
	User data for the `accumulator`.
	The argument can be `NULL`.
`c_marshaller`	`GSignalCMarshaller`
	The function to translate arrays of parameter values to signal emissions into C language callback invocations or `NULL`.
	The argument can be `NULL`.
`return_type`	`GType`
	The type of return value, or #G_TYPE_NONE for a signal without a return value.
`n_params`	`guint`
	The length of `param_types`.
`param_types`	An array of `GType`
	An array of types, one for each parameter (may be `NULL` if `n_params` is zero)
	The argument can be `NULL`.
	The length of the array is specified in the `n_params` argument.
	The data is owned by the caller of the function.

Return value

Returns:	`guint`
	The signal id.
