2
3 A menu is a popup (or pull down) list of items, one of which may be
4 selected before the menu goes away (clicking elsewhere dismisses the
5 menu). Menus may be used to construct either menu bars or popup menus.
6
7 A menu item has an integer ID associated with it which can be used to
8 identify the selection, or to change the menu item in some way.

20
21 If the menu is part of a menubar, then \helpref{wxMenuBar}{wxmenubar} event processing is used.
22
23 With a popup menu, there is a variety of ways to handle a menu selection event
24 (wxEVT\_COMMAND\_MENU\_SELECTED).
25
26 \begin{enumerate}\itemsep=0pt
27 \item Derive a new class from wxMenu and define event table entries using the EVT\_MENU macro.
28 \item Set a new event handler for wxMenu, using an object whose class has EVT\_MENU entries.
29 \item Provide EVT\_MENU handlers in the window which pops up the menu, or in an ancestor of
30 this window.
31 \item Define a callback of type wxFunction, which you pass to the wxMenu constructor.
32 The callback takes a reference to the menu, and a reference to a
33 \helpref{wxCommandEvent}{wxcommandevent}. This method is deprecated and should
34 not be used in the new code, it is provided for backwards compatibility only.

44 \membersection{wxMenu::wxMenu}\label{wxmenuconstr}
45
46 \func{}{wxMenu}{\param{const wxString\& }{title = ""}, \param{long}{ style = 0}}
47
48 Constructs a wxMenu object.
49
50 \wxheading{Parameters}
51
52 \docparam{title}{A title for the popup menu: the empty string denotes no title.}
53
54 \docparam{style}{If set to {\tt wxMENU\_TEAROFF}, the menu will be detachable.}
55
56 \func{}{wxMenu}{\param{long}{ style}}
57
58 Constructs a wxMenu object.
59
60 \wxheading{Parameters}
61
62 \docparam{style}{If set to {\tt wxMENU\_TEAROFF}, the menu will be detachable.}
63
64 \membersection{wxMenu::\destruct{wxMenu}}
65
66 \func{}{\destruct{wxMenu}}{\void}
67
68 Destructor, destroying the menu.
69
70 Note: under Motif, a popup menu must have a valid parent (the window
71 it was last popped up on) when being destroyed. Therefore, make sure
72 you delete or re-use the popup menu {\it before} destroying the
73 parent window. Re-use in this context means popping up the menu on
74 a different window from last time, which causes an implicit destruction
75 and recreation of internal data structures.
76
77 \membersection{wxMenu::Append}\label{wxmenuappend}
78
79 \func{void}{Append}{\param{int}{ id}, \param{const wxString\& }{ item}, \param{const wxString\& }{helpString = ""},\rtfsp

81
82 Adds a string item to the end of the menu.
83
84 \func{void}{Append}{\param{int}{ id}, \param{const wxString\& }{ item}, \param{wxMenu *}{subMenu},\rtfsp
85 \param{const wxString\& }{helpString = ""}}
86
87 Adds a pull-right submenu to the end of the menu.
88
89 \func{void}{Append}{\param{wxMenuItem*}{ menuItem}}
90
91 Adds a menu item object. This is the most generic variant of Append() method
92 because it may be used for both items (including separators) and submenus and
93 because you can also specify various extra properties of a menu item this way,
94 such as bitmaps and fonts.
95
96 \wxheading{Parameters}
97
98 \docparam{id}{The menu command identifier.}
99
100 \docparam{item}{The string to appear on the menu item.}
101
102 \docparam{menu}{Pull-right submenu.}
103
104 \docparam{checkable}{If TRUE, this item is checkable.}
105
106 \docparam{helpString}{An optional help string associated with the item.
107 By default, \helpref{wxFrame::OnMenuHighlight}{wxframeonmenuhighlight} displays
108 this string in the status line.}
109
110 \docparam{menuItem}{A menuitem object. It will be owned by the wxMenu object after this function
111 is called, so do not delete it yourself.}
112
113 \wxheading{Remarks}
114
115 This command can be used after the menu has been shown, as well as on initial
116 creation of a menu or menubar.

446 Sends events to {\it source} (or owning window if NULL) to update the
447 menu UI. This is called just before the menu is popped up with \helpref{wxWindow::PopupMenu}{wxwindowpopupmenu}, but
448 the application may call it at other times if required.

464
465 <wx/menu.h>
466
467 \wxheading{Event handling}
468
469 To respond to a menu selection, provide a handler for EVT\_MENU, in the frame
470 that contains the menu bar. If you have a toolbar which uses the same identifiers
471 as your EVT\_MENU entries, events from the toolbar will also be processed by your
472 EVT\_MENU event handlers.
473
474 Note that menu commands (and UI update events for menus) are first sent to
475 the focus window within the frame. If no window within the frame has the focus,
476 then the events are sent directly to the frame. This allows command and UI update
477 handling to be processed by specific windows and controls, and not necessarily
478 by the application frame.
