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.

This function is not directly available to language bindings.

Parameters

signal_name

Type: 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

Type: GType

The type this signal pertains to. It will also pertain to types which are derived from this type.

signal_flags

Type: 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

Type: 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

Type: GSignalAccumulator

The accumulator for this signal; may be NULL.

The argument can be NULL.
accu_data

Type: gpointer

User data for the accumulator.

The argument can be NULL.
The data is owned by the caller of the function.
c_marshaller

Type: 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

Type: GType

The type of return value, or G_TYPE_NONE for a signal without a return value.

n_params

Type: guint

The length of param_types.

param_types

Type: 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

Type: guint

The signal id.
