Re: weak pointer

["Bram Neijt" <bneijt gmail com>]

The g-object-weak-ref is probably the neatest way of creating a weak
pointer class in glibmm, because it's a glib function. However, I have
never worked with it and probably won't be able to get something that
would be considered good enough to include in the distribution.

Making a working weak pointer class that simply inherits the RefPtr
and calles unreference on when created is something I could do. Then
you can ask the WeakPtr to create a RefPtr, just like BOOST does that
( http://www.boost.org/libs/smart_ptr/weak_ptr.htm ). The class would
then just check if the RefPtr is still valid before creating a copy of
it, throwing an Exception when it doesn't work.

Although the first is probably the best solution, I can't do that so
somebody else would have to be willing or knowledgeable enough to
create it.

Anyone on the team willing to take it up, or should I just start
working on the inherited solution and see how that works out?
