Method

GObjectParamSpecset_qdata

Declaration

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

Description

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 GQuark
 

A GQuark, naming the user data pointer.

data gpointer
 

An opaque user data pointer.
