set_qdata

Description:

public void set_qdata (Quark quark, void* data)

Sets an opaque, named pointer on a ParamSpec.

The name is specified through a Quark (retrieved e.g. via g_quark_from_static_string), and the pointer can be gotten back from the this with 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:

this	the ParamSpec to set store a user data pointer
quark	a Quark, naming the user data pointer
data	an opaque user data pointer
