\section{\class{wxFileHistory}}\label{wxfilehistory}

The wxFileHistory encapsulates a user interface convenience, the
list of most recently visited files as shown on a menu (usually the File menu).

wxFileHistory can manage one or more file menus. More than one menu may be required
in an MDI application, where the file history should appear on each MDI child menu
as well as the MDI parent frame.

\membersection{wxFileHistory::m\_fileHistory}\label{wxfilehistorymfilehistory}

\member{char**}{m\_fileHistory}

A character array of strings corresponding to the most recently opened
files.


\membersection{wxFileHistory::m\_fileHistoryN}\label{wxfilehistorymfilehistoryn}

\member{size\_t}{m\_fileHistoryN}

The number of files stored in the history array.


\membersection{wxFileHistory::m\_fileMaxFiles}\label{wxfilehistorymfilemaxfiles}

\member{size\_t}{m\_fileMaxFiles}

The maximum number of files to be stored and displayed on the menu.


\membersection{wxFileHistory::m\_fileMenu}\label{wxfilehistorymfilemenu}

\member{wxMenu*}{m\_fileMenu}

The file menu used to display the file history list (if enabled).


\membersection{wxFileHistory::wxFileHistory}\label{wxfilehistoryctor}

\func{}{wxFileHistory}{\param{size\_t}{ maxFiles = 9}, \param{wxWindowID}{ idBase = wxID\_FILE1}}

Constructor. Pass the maximum number of files that should be stored and
displayed.

{\it idBase} defaults to wxID\_FILE1 and represents the id given to the first
history menu item.  Since menu items can't share the same ID you should change
idBase (To one of your own defined IDs) when using more than one wxFileHistory
in your application.


\membersection{wxFileHistory::\destruct{wxFileHistory}}\label{wxfilehistorydtor}

\func{}{\destruct{wxFileHistory}}{\void}

Destructor.


\membersection{wxFileHistory::AddFileToHistory}\label{wxfilehistoryaddfiletohistory}

\func{void}{AddFileToHistory}{\param{const wxString\& }{filename}}

Adds a file to the file history list, if the object has a pointer to an appropriate file menu.


\membersection{wxFileHistory::AddFilesToMenu}\label{wxfilehistoryaddfilestomenu}

\func{void}{AddFilesToMenu}{\void}\label{wxfilehistoryaddfilestomenu}

Appends the files in the history list, to all menus managed by the file history object.

\func{void}{AddFilesToMenu}{\param{wxMenu*}{ menu}}

Appends the files in the history list, to the given menu only.


\membersection{wxFileHistory::GetCount}\label{wxfilehistorygetcount}

\constfunc{size\_t}{GetCount}{\void}

Returns the number of files currently stored in the file history.


\membersection{wxFileHistory::GetHistoryFile}\label{wxfilehistorygethistoryfile}

\constfunc{wxString}{GetHistoryFile}{\param{size\_t}{ index}}

Returns the file at this index (zero-based).


\membersection{wxFileHistory::GetMaxFiles}\label{wxfilehistorygetmaxfiles}

\constfunc{int}{GetMaxFiles}{\void}

Returns the maximum number of files that can be stored.


\membersection{wxFileHistory::GetMenus}\label{wxfilehistorygetmenus}

\constfunc{const wxList\&}{GetMenus}{\void}

Returns the list of menus that are managed by this file history object.

Saves the file history into the given config object. This must be called
explicitly by the application.

\membersection{wxFileHistory::UseMenu}\label{wxfilehistoryusemenu}

\func{void}{UseMenu}{\param{wxMenu* }{menu}}

Also see \helpref{AddFilesToMenu()}{wxfilehistoryaddfilestomenu} for
initializing the menu with filenames that are already in the history when this
function is called, as this is not done automatically.
