+One of the failings of C++ used to be that no runtime information was provided
about a class and its position in the inheritance hierarchy. Another, which
still persists, is that instances of a class cannot be created just by knowing
the name of a class, which makes facilities such as persistent storage hard to
and functions and wxWidgets is no exception. As it originated before the
addition of RTTI to the C++ standard and as support for it is still missing
from some (albeit old) compilers, wxWidgets doesn't (yet) use it, but provides
-it's own macro-based RTTI system.

In the future, the standard C++ RTTI will be used though and you're encouraged
to use whenever possible the wxDynamicCast macro which, for the implementations
given type, by supplying a string name. If you have a pointer to the
wxClassInfo object instead, then you can simply call wxClassInfo::CreateObject.
