The AppendMenu function appends a new item to the end of the specified menu bar, drop-down menu, submenu, or shortcut menu. You can use this function to specify the content, appearance, and behavior of the menu item.
The AppendMenu function has been superseded by the InsertMenuItem function. You can still use AppendMenu, however, if you do not need any of the extended features of InsertMenuItem.
BOOL AppendMenu(
|
HMENU hMenu, |
// handle to menu to be changed |

UINT uFlags, |
// menu-item flags |
|
UINT uIDNewItem, |
// menu-item identifier or handle of drop-down menu or submenu |

Description |
|
MF_BITMAP |
Contains a bitmap handle. |
|
MF_OWNERDRAW |
Contains a 32-bit value supplied by the application that can be used to maintain additional data related to the menu item. The value is in the itemData member of the structure pointed to by the lparam parameter of the WM_MEASURE or WM_DRAWITEM message sent when the menu is created or its appearance is updated. |
|
MF_STRING |
Contains a pointer to a null-terminated string. |
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The application must call the DrawMenuBar function whenever a menu changes, whether or not the menu is in a displayed window.

Value |
Description |
|
MF_BITMAP |
Uses a bitmap as the menu item. The lpNewItem parameter contains the handle to the bitmap. |
|
MF_CHECKED |
Places a check mark next to the menu item. If the application provides check-mark bitmaps (see SetMenuItemBitmaps), this flag displays the check mark bitmap next to the menu item. |
|
MF_DISABLED |
Disables the menu item so it cannot be selected, but the flag does not gray it. |
|
MF_ENABLED |
Enables the menu item so it can be selected, and restores it from its grayed state. |
|
MF_GRAYED |
Disables the menu item and grays it so it cannot be selected. |
|
MF_MENUBARBREAK |
Functions the same as the MF_MENUBREAK flag for a menu bar. For a drop-down menu, submenu, or shortcut menu, the new column is separated from the old column by a vertical line. |
|
MF_MENUBREAK |
Places the item on a new line (for a menu bar) or in a new column (for a drop-down menu, submenu, or shortcut menu) without separating columns. |
|
MF_OWNERDRAW |
Specifies that the item is an owner-drawn item. Before the menu is displayed for the first time, the window that owns the menu receives a WM_MEASUREITEM message to retrieve the width and height of the menu item. The WM_DRAWITEM message is then sent to the window procedure of the owner window whenever the appearance of the menu item must be updated. |
|
MF_POPUP |
Specifies that the menu item opens a drop-down menu or submenu. The uIDNewItem parameter specifies the handle to the drop-down menu or submenu. This flag is used to add a menu name to a menu bar, or a menu item that opens a submenu to a drop-down menu, submenu, or shortcut menu. |
|
MF_SEPARATOR |
Draws a horizontal dividing line. This flag is used only in a drop-down menu, submenu, or shortcut menu. The line cannot be grayed, disabled, or highlighted. The lpNewItem and uIDNewItem parameters are ignored. |
|
MF_STRING |
Specifies that the menu item is a text string; the lpNewItem parameter points to the string. |
|
MF_UNCHECKED |
Does not place a check mark next to the item (default). If the application supplies check-mark bitmaps (see SetMenuItemBitmaps), this flag displays the unchecked bitmap next to the menu item. |
The following groups of flags cannot be used together:
CreateMenu, DeleteMenu, DestroyMenu, DrawMenuBar, InsertMenu, InsertMenuItem, ModifyMenu, RemoveMenu, SetMenuItemBitmaps
