<H2>wxNodeBase</H2>
<P>
A node structure used in linked lists (see <A HREF="wx127.htm#wxlist">wxList</A>) and
derived classes. You should never use wxNodeBase class directly because it
works with untyped (void *) data and this is unsafe. Use wxNode-derived classes
which are defined by WX_DECLARE_LIST and WX_DEFIBE_LIST macros instead as
described in <A HREF="wx127.htm#wxlist">wxList</A> documentation (see example there). wxNode
is defined for compatibility as wxNodeBase containing "wxObject *" pointer, but
usage of this class is deprecated.<P>
