set_qdata

Description:

[ CCode ( simple_generics = true ) ]
public void set_qdata<T> (Quark quark, owned T data)

This sets an opaque, named pointer on a miniobject.

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 until the this is disposed. Setting a previously set user data pointer, overrides (frees) the old pointer set, using null as pointer essentially removes the data stored.

destroy may be specified which is called with data as argument when the this is disposed, or the data is being overwritten by a call to set_qdata with the same quark.

Parameters:

this	a MiniObject
quark	A Quark, naming the user data pointer
data	An opaque user data pointer
destroy	Function to invoke with `data` as argument, when `data` needs to be freed
