Detailed Description

A menu item represents an item in a menu.

Note that you usually don't have to deal with it directly as wxMenu methods usually construct an object of this class for you.

Also please note that the methods related to fonts and bitmaps are currently only implemented for Windows, Mac and GTK+.

Library:  wxCore

Constructor & Destructor Documentation

wxMenuItem::wxMenuItem ( wxMenu parentMenu = NULL,
int  id = wxID_SEPARATOR,
const wxString text = wxEmptyString,
const wxString helpString = wxEmptyString,
wxItemKind  kind = wxITEM_NORMAL,
wxMenu subMenu = NULL 
)

Constructs a wxMenuItem object.

Menu items can be standard, or "stock menu items", or custom. For the standard menu items (such as commands to open a file, exit the program and so on, see Stock items for the full list) it is enough to specify just the stock ID and leave text and helpString empty.

In fact, leaving at least text empty for the stock menu items is strongly recommended as they will have appearance and keyboard interface (including standard accelerators) familiar to the user.

For the custom (non-stock) menu items, text must be specified and while helpString may be left empty, it's recommended to pass the item description (which is automatically shown by the library in the status bar when the menu item is selected) in this parameter.

Finally note that you can e.g. use a stock menu label without using its stock help string:

        // use all stock properties:
        helpMenu->Append(wxID_ABOUT);

        // use the stock label and the stock accelerator but not the stock help string:
        helpMenu->Append(wxID_ABOUT, wxEmptyString, wxT("My custom help string"));

        // use all stock properties except for the bitmap:
        wxMenuItem *mymenu = new wxMenuItem(helpMenu, wxID_ABOUT);
        mymenu->SetBitmap(wxArtProvider::GetBitmap(wxART_WARNING));
        helpMenu->Append(mymenu);

that is, stock properties are set independently one from the other.

Parameters:
parentMenu Menu that the menu item belongs to. Can be NULL if the item is going to be added to the menu later.
id Identifier for this menu item. May be wxID_SEPARATOR, in which case the given kind is ignored and taken to be wxITEM_SEPARATOR instead.
text Text for the menu item, as shown on the menu. An accelerator key can be specified using the ampersand " character. In order to embed an ampersand character in the menu item text, the ampersand must be doubled.
helpString Optional help string that will be shown on the status bar.
kind May be wxITEM_SEPARATOR, wxITEM_NORMAL, wxITEM_CHECK or wxITEM_RADIO.
subMenu If non-NULL, indicates that the menu item is a submenu.

virtual wxMenuItem::~wxMenuItem (  )  [virtual]

Destructor.
