Re: Gtk::Window and GtkWindow

[Ian Martin <martin_id vodafone co nz>]

Hi Russel,
Sorry, wasn't supposed to be off-list; we've all had to hunt down the 
answer to questions answered off list before, and knowing someone else 
has asked it doesn't help anyone looking later.

In the docs every class has a wrap() method associated with it.  I agree 
the general idea is not well documented, but then there shouldn't be the 
need to use them; if you're having to use wrap() then there's something 
missing in gtkmm, and it's probably better to fix that than plan to use 
C routinely.

The other piece of relevant information is that some objects are owned 
by another - Gtk::Adjustment is a good example; these are only provided 
via a RefPtr, rather than a raw pointer.  Also, before you update the 
docs, from a recent thread on the mailing list it's possible all 
pointers may be deprecated soon in favour of some form of smart 
pointer.  That'd be a significant improvement from a C++ perspective, 
but I believe the mechanics of it are still being ironed out.

Ian.
