    @class wxMenuItem
    @wxheader{menuitem.h}

    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 and GTK+.

class wxMenuItem : public wxObject
{
public:
    /**
        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 @ref overview_stockitems "stock items" for the full list) it is enough
        to
        specify just the stock ID and leave @a text and @a helpString empty. In
        fact, leaving at least @a 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, @a text must be specified and while
        @a 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:

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

        @param parentMenu
            Menu that the menu item belongs to.
        @param id
            Identifier for this menu item, or wxID_SEPARATOR to indicate a separator.
        @param 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.
        @param helpString
            Optional help string that will be shown on the status bar.
        @param kind
            May be wxITEM_SEPARATOR, wxITEM_NORMAL,
            wxITEM_CHECK or wxITEM_RADIO
        @param subMenu
            If non-@NULL, indicates that the menu item is a submenu.
