In fact, window is defined thus:
typedef boost::shared_ptr<window_base> window;
The reason is that widgets are always reference-counted. The alternative
would have been to make window a pimpl class, with the impl being
reference counted. However, since I wanted to use the factory pattern to
firewall the implementation of widgets, I would have to have my widgets on
the heap anyway, so I just made widget a shared pointer to the WDT (whole
damn thing).
Does that make sense? :-)
