setQdata

open fun setQdata(quark: <Error class: unknown class>, data: <Error class: unknown class>? = null)

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

a #GQuark, naming the user data pointer

data

an opaque user data pointer
