\section{\class{wxMenu}}\label{wxmenu}

A menu is a popup (or pull down) list of items, one of which may be
selected before the menu goes away (clicking elsewhere dismisses the
menu).  Menus may be used to construct either menu bars or popup menus.

A menu item has an integer ID associated with it which can be used to
identify the selection, or to change the menu item in some way.

\wxheading{Derived from}

<wx/menu.h>

\wxheading{Event handling}

If the menu is part of a menubar, then \helpref{wxMenuBar}{wxmenubar} event processing is used.

With a popup menu, there is a variety of ways to handle a menu selection event
(wxEVT\_COMMAND\_MENU\_SELECTED).

\begin{enumerate}\itemsep=0pt
\item Derive a new class from wxMenu and define event table entries using the EVT\_MENU macro.
\item Set a new event handler for wxMenu, using an object whose class has EVT\_MENU entries.
\item Provide EVT\_MENU handlers in the window which pops up the menu, or in an ancestor of
this window.
\item Define a callback of type wxFunction, which you pass to the wxMenu constructor.
The callback takes a reference to the menu, and a reference to a
\helpref{wxCommandEvent}{wxcommandevent}. This method is deprecated and should
not be used in the new code, it is provided for backwards compatibility only.
\end{enumerate}

\membersection{wxMenu::wxMenu}\label{wxmenuconstr}

\func{}{wxMenu}{\param{const wxString\& }{title = ""}, \param{long}{ style = 0}}

Constructs a wxMenu object.

\wxheading{Parameters}

\docparam{title}{A title for the popup menu: the empty string denotes no title.}

\docparam{style}{If set to {\tt wxMENU\_TEAROFF}, the menu will be detachable.}

\func{}{wxMenu}{\param{long}{ style}}

Constructs a wxMenu object.

\wxheading{Parameters}

\docparam{style}{If set to {\tt wxMENU\_TEAROFF}, the menu will be detachable.}

\membersection{wxMenu::\destruct{wxMenu}}

\func{}{\destruct{wxMenu}}{\void}

Destructor, destroying the menu.

Note: under Motif, a popup menu must have a valid parent (the window
it was last popped up on) when being destroyed. Therefore, make sure
you delete or re-use the popup menu {\it before} destroying the
parent window. Re-use in this context means popping up the menu on
a different window from last time, which causes an implicit destruction
and recreation of internal data structures.

\membersection{wxMenu::Append}\label{wxmenuappend}

\func{void}{Append}{\param{int}{ id}, \param{const wxString\& }{ item}, \param{const wxString\& }{helpString = ""},\rtfsp
\param{const bool}{ checkable = FALSE}}

Adds a string item to the end of the menu.

\func{void}{Append}{\param{int}{ id}, \param{const wxString\& }{ item}, \param{wxMenu *}{subMenu},\rtfsp
\param{const wxString\& }{helpString = ""}}

Adds a pull-right submenu to the end of the menu.

\func{void}{Append}{\param{wxMenuItem*}{ menuItem}}

Adds a menu item object. This is the most generic variant of Append() method
because it may be used for both items (including separators) and submenus and
because you can also specify various extra properties of a menu item this way,
such as bitmaps and fonts.

\wxheading{Parameters}

\docparam{id}{The menu command identifier.}

\docparam{item}{The string to appear on the menu item.}

\docparam{menu}{Pull-right submenu.}

\docparam{checkable}{If TRUE, this item is checkable.}

\docparam{helpString}{An optional help string associated with the item.
By default, \helpref{wxFrame::OnMenuHighlight}{wxframeonmenuhighlight} displays
this string in the status line.}

\docparam{menuItem}{A menuitem object. It will be owned by the wxMenu object after this function
is called, so do not delete it yourself.}

\wxheading{Remarks}

This command can be used after the menu has been shown, as well as on initial
creation of a menu or menubar.

\helpref{wxUpdateUIEvent}{wxupdateuievent}

\section{\class{wxMenuBar}}\label{wxmenubar}

A menu bar is a series of menus accessible from the top of a frame.

\wxheading{Derived from}

\helpref{wxEvtHandler}{wxevthandler}\\
\helpref{wxObject}{wxobject}

\wxheading{Include files}

<wx/menu.h>

\wxheading{Event handling}

To respond to a menu selection, provide a handler for EVT\_MENU, in the frame
that contains the menu bar. If you have a toolbar which uses the same identifiers
as your EVT\_MENU entries, events from the toolbar will also be processed by your
EVT\_MENU event handlers.

Note that menu commands (and UI update events for menus) are first sent to
the focus window within the frame. If no window within the frame has the focus,
then the events are sent directly to the frame. This allows command and UI update
handling to be processed by specific windows and controls, and not necessarily
by the application frame.
