Re: Basic question refPtr

["Andrew E. Makeev" <andrew solvo ru>]

Well, in common words, that wrapper handles reference counting on some
object. So, that object could be destroyed once all references were
removed. ( It is not std::auto_ptr<> )

Simple example.

You could create Pixbuf (from file, data). Pixbuf object has no
references yet. So, if you create another pixbuf and assign it to same
RefPtr, then old object will be destroyed.

But, if you first will assign old Pixbuf to some Image widget, then it
will have reference++, and won't be destroyed when you recreating
RefPtr. It should be destroyed now once Image widget unreferenced it.

Hope, that clear enough.
