const gchar* signal_name,
GType itype,
GSignalFlags signal_flags,
GClosure* class_closure,
GSignalAccumulator accumulator,
gpointer accu_data,
GSignalCMarshaller c_marshaller,

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.
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:
GTypeThe type this signal pertains to. It will also pertain to types which are derived from this type.
signal_flags-
Type:
GSignalFlagsA combination of
GSignalFlagsspecifying detail of when the default handler is to be invoked. You should at least specifyG_SIGNAL_RUN_FIRSTorG_SIGNAL_RUN_LAST. class_closure-
Type:
GClosureThe 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:
GSignalAccumulatorThe accumulator for this signal; may be
NULL.The argument can be NULL. accu_data-
Type:
gpointerUser data for the
accumulator.The argument can be NULL.The data is owned by the caller of the function. c_marshaller-
Type:
GSignalCMarshallerThe 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:
GTypeThe type of return value, or
G_TYPE_NONEfor a signal without a return value. n_params-
Type:
guintThe number of parameter types in
args. args-
Type:
va_listVa_list of
GType, one for each parameter.
