set_qdata_full

Description:

public void set_qdata_full (Quark quark, void* data, DestroyNotify? destroy)

This function works like g_object_set_qdata, but in addition, a void (*destroy) (gpointer) function may be specified which is called with data as argument when the this is finalized, or the data is being overwritten by a call to g_object_set_qdata with the same quark.

Parameters:

this	The GObject to set store a user data pointer
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
