Question about memory in GTK+2.x....

[FMorales <altf2o attbi com>]

Hello i had a quick question about allocating widgets in GTK+2.x...
I haven't gotten into /alot/ of programming with 2.x yet, but i thought 
i remembered a
"gtk_destroy", type function to destroy objects (widgets) created 
dynamically in 1.2 ... I.e. :

GtkWidget * window = gtk_window_new(GTK_TOPLEVEL_WINDOW);
............
gtk_destroy(window); /* could have been gtk_destroy_object(window) , or 
similar IIRC */
............

Now i don't see an equivilant function for 2.x releases, maybe i just 
missed it... I've seen
references to some *_unref_* type functions, but not sure if that's what 
i should be using,
or if once the reference count hits 0 if i still have to free the memory 
myself.

In some of the FAQ's i noticed a question asking why Gtk\Glib leaked 
memory, but that
seemed to have more to do with using Glibs memory allocation functions, 
not allocating
widgets...

So is there Garbage Collection in 2.x that handles the allocation of 
widgets specifically ?
Or some equivalant to it, that keeps me from having to go through and 
free up all those
widgets i used ? Or is there something i'm missing ?

Thx again in advance, ....FrankM....
