wxnodebase is the node structure used in linked lists (see wxlist) and derived classes. you should never use wxnodebase class directly, however, because it works with untyped (void *) data and this is unsafe. use wxnodebase-derived classes which are automatically defined by wx_declare_list and wx_define_list macros instead as described in wxlist documentation (see example there). also note that although there is a class called wxnode, it is defined for backwards compatibility only and usage of this class is strongly deprecated.
in the documentation below, the type t should be thought of as a "template'' parameter: this is the type of data stored in the linked list or, in other words, the first argument of wx_declare_list macro. also, wxnode is written as wxnode<t> even though it isn't really a template class -- but it helps to think of it as if it were.

t * getdata() const
retrieves the client data pointer associated with the node.
wxnode<t> * getnext() const
retrieves the next node or null if this node is the last one.
wxnode<t> * getprevious()
retrieves the previous node or null if this node is the first one in the list.
void setdata(t *data)
sets the data associated with the node (usually the pointer will have been set when the node was created).
int indexof()
returns the zero-based index of this node within the list. the return value will be wxnot_found if the node has not been added to a list yet.
