Method

GObjectParamSpecset_qdata

Declaration [src]

void
g_param_spec_set_qdata (
  GParamSpec* pspec,
  GQuark quark,
  gpointer data
)

Description [src]

Sets an opaque, named pointer on a GParamSpec. The name is specified through a GQuark (retrieved e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the pspec with g_param_spec_get_qdata(). Setting a previously set user data pointer, overrides (frees) the old pointer set, using NULL as pointer essentially removes the data stored.

Parameters

quark

Type: GQuark

A GQuark, naming the user data pointer.

data

Type: gpointer

An opaque user data pointer.

The argument can be NULL.

The data is owned by the caller of the method.
