still defined, but their usage is deprecated and they will disappear in the
future versions completely.
+In the documentation of the list classes below, you should replace wxNode with
+wxListName::Node and wxObject with the list element type (i.e. the first
+parameter of WX\_DECLARE\_LIST) for the template lists.

See \helpref{wxNode}{wxnode} for members that retrieve the data associated with a node, and
members for getting to the next or previous node.
-Note that a cast is required when retrieving the data from a node. Although a
-node is defined to store objects of type {\bf wxObject} and derived types, other
-types (such as char*) may be used with appropriate casting.

\wxheading{See also}
\helpref{wxNode}{wxnode}, \helpref{wxStringList}{wxstringlist},
Destroys the list. Also destroys any remaining nodes, but does not destroy
client data held in the nodes.
-\membersection{wxList::Append}
+\membersection{wxList::Append}\label{wxlistappend}
\func{wxNode *}{Append}{\param{wxObject *}{object}}
The key string is copied and stored by the list implementation.
-\membersection{wxList::Clear}
+\membersection{wxList::Clear}\label{wxlistclear}
\func{void}{Clear}{\void}
If {\it destroy} is TRUE, instructs the list to call {\it delete} on the client contents of
a node whenever the node is destroyed. The default is FALSE.
-\membersection{wxList::DeleteNode}
+\membersection{wxList::DeleteNode}\label{wxlistdeletenode}
\func{bool}{DeleteNode}{\param{wxNode *}{node}}
Deletes the given node from the list, returning TRUE if successful.
-\membersection{wxList::DeleteObject}
+\membersection{wxList::DeleteObject}\label{wxlistdeleteobject}
\func{bool}{DeleteObject}{\param{wxObject *}{object}}
Finds the given client {\it object} and deletes the appropriate node from the list, returning
TRUE if successful. The application must delete the actual object separately.
-\membersection{wxList::Find}
+\membersection{wxList::Find}\label{wxlistfind}
\func{wxNode *}{Find}{\param{long}{ key}}
Returns the node whose stored key matches {\it key}. Use on a keyed list only.
-\membersection{wxList::GetFirst}
+\membersection{wxList::GetCount}\label{wxlistgetcount}
+
+\constfunc{size\_t}{GetCount}{\void}
+
+Returns the number of elements in the list.
+
+\membersection{wxList::GetFirst}\label{wxlistgetfirst}
\func{wxNode *}{GetFirst}{\void}
Returns the first node in the list (NULL if the list is empty).
-\membersection{wxList::IndexOf}
+\membersection{wxList::GetLast}\label{wxlistgetlast}
+
+\func{wxNode *}{GetLast}{\void}
+
+Returns the last node in the list (NULL if the list is empty).
+
+\membersection{wxList::IndexOf}\label{wxlistindexof}
\func{int}{IndexOf}{\param{wxObject*}{ obj }}
Returns the index of {\it obj} within the list or NOT\_FOUND if {\it obj}
is not found in the list.
-\membersection{wxList::Insert}
+\membersection{wxList::Insert}\label{wxlistinsert}
\func{wxNode *}{Insert}{\param{wxObject *}{object}}
Insert object at front of list.
-\func{wxNode *}{Insert}{\param{wxNode *}{position}, \param{wxObject *}{object}}
+\func{wxNode *}{Insert}{\param{size\_t }{position}, \param{wxObject *}{object}}
-Insert object before {\it position}.
+Insert object before {\it position}, i.e. the index of the new item in the
+list will be equal to {\it position}. {\it position} should be less than or
+equal to \helpref{GetCount}{wxlistgetcount}; if it is equal to it, this is the
+same as calling \helpref{Append}{wxlistappend}.
+\func{wxNode *}{Insert}{\param{wxNode *}{node}, \param{wxObject *}{object}}
-\membersection{wxList::GetLast}
+Inserts the object before the given {\it node}.
-\func{wxNode *}{GetLast}{\void}
+\membersection{wxList::Item}\label{wxlistitem}
-Returns the last node in the list (NULL if the list is empty).
+\constfunc{wxNode *}{Item}{\param{size\_t }{index}}
+
+Returns the node at given position in the list.
-\membersection{wxList::Member}
+\membersection{wxList::Member}\label{wxlistmember}
\func{wxNode *}{Member}{\param{wxObject *}{object}}
+{\bf NB:} This function is deprecated, use \helpref{Find}{wxlistfind} instead.
+
Returns the node associated with {\it object} if it is in the list, NULL otherwise.
-\membersection{wxList::Nth}
+\membersection{wxList::Nth}\label{wxlistnth}
\func{wxNode *}{Nth}{\param{int}{ n}}
+{\bf NB:} This function is deprecated, use \helpref{Item}{wxlistitem} instead.
+
Returns the {\it nth} node in the list, indexing from zero (NULL if the list is empty
or the nth node could not be found).
-\membersection{wxList::Number}
+\membersection{wxList::Number}\label{wxlistnumber}
\func{int}{Number}{\void}
+{\bf NB:} This function is deprecated, use \helpref{GetCount}{wxlistgetcount} instead.
+
Returns the number of elements in the list.
-\membersection{wxList::Sort}
+\membersection{wxList::Sort}\label{wxlistsort}
\func{void}{Sort}{\param{wxSortCompareFunction}{ compfunc}}
}
