wxList classes provide linked list functionality for wxWindows, and for an
application if it wishes. Depending on the form of constructor used, a list
-can be keyed on integer or string keys to provide a primitive look-up ability.

See \helpref{wxHashMap}{wxhashmap}\rtfsp for a faster method of storage
when random access is required.

-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.
+In the documentation of the list classes below, the template notations are
+used even though these classes are not really templates at all -- but it helps
+to think about them as if they were. You should replace wxNode<T> with
+wxListName::Node and T itself with the list element type (i.e. the first
+parameter of WX\_DECLARE\_LIST).

Constructors. {\it key\_type} is one of wxKEY\_NONE, wxKEY\_INTEGER, or wxKEY\_STRING,
and indicates what sort of keying is required (if any).

+\func{wxNode<T> *}{Append}{\param{long}{ key}, \param{T *}{object}}
-Appends a new {\bf wxNode} to the end of the list and puts a pointer to the
-\rtfsp{\it object} in the node. The last two forms store a key with the object for
-later retrieval using the key. The new node is returned in each case.

+with the object for later retrieval using the key. The new node is returned in
+each case.
The key string is copied and stored by the list implementation.
\func{void}{Clear}{\void}
Clears the list (but does not delete the client data stored with each node
-unless you called DeleteContents(TRUE), in which case it deletes data).
+unless you called DeleteContents({\tt true}), in which case it deletes data).
\membersection{wxList::DeleteContents}\label{wxlistdeletecontents}
\func{void}{DeleteContents}{\param{bool}{ destroy}}
-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.
+If {\it destroy} is {\tt true}, instructs the list to call {\it delete} on the client contents of

\membersection{wxList::DeleteNode}\label{wxlistdeletenode}
-\func{bool}{DeleteNode}{\param{wxNode *}{node}}
+\func{bool}{DeleteNode}{\param{wxNode<T> *}{node}}
-Deletes the given node from the list, returning TRUE if successful.
+Deletes the given node from the list, returning {\tt true} if successful.
\membersection{wxList::DeleteObject}\label{wxlistdeleteobject}
-\func{bool}{DeleteObject}{\param{wxObject *}{object}}
+\func{bool}{DeleteObject}{\param{T *}{object}}
Finds the given client {\it object} and deletes the appropriate node from the list, returning

\membersection{wxList::Find}\label{wxlistfind}
-\func{wxNode *}{Find}{\param{long}{ key}}
+\func{wxNode<T> *}{Find}{\param{T *}{ object}}
+
+Returns the node whose client date is {\it object} or NULL if none found.

+
+\func{wxNode<T> *}{Find}{\param{long}{ key}}
+
+\func{wxNode<T> *}{Find}{\param{const wxString\& }{key}}
Returns the node whose stored key matches {\it key}. Use on a keyed list only.
\membersection{wxList::GetFirst}\label{wxlistgetfirst}
-\func{wxNode *}{GetFirst}{\void}
+\func{wxNode<T> *}{GetFirst}{\void}
Returns the first node in the list (NULL if the list is empty).
\membersection{wxList::GetLast}\label{wxlistgetlast}
-\func{wxNode *}{GetLast}{\void}
+\func{wxNode<T> *}{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 }}
+\func{int}{IndexOf}{\param{T*}{ obj }}
Returns the index of {\it obj} within the list or wxNOT\_FOUND if {\it obj}
is not found in the list.
\membersection{wxList::Insert}\label{wxlistinsert}

-\func{wxNode *}{Insert}{\param{size\_t }{position}, \param{wxObject *}{object}}
+\func{wxNode<T> *}{Insert}{\param{size\_t }{position}, \param{T *}{object}}
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}}
+\func{wxNode<T> *}{Insert}{\param{wxNode<T> *}{node}, \param{T *}{object}}

+
+Returns {\tt true} if the list is empty, {\tt false} otherwise.
