Description [src]

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.


signal_name const gchar*

The name for the signal.

 The data is owned by the caller of the function.
 The string 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.

accu_data gpointer

User data for the accumulator.

c_marshaller GSignalCMarshaller

The function to translate arrays of parameter values to signal emissions into C language callback invocations or 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.
