The MENUITEMINFO structure contains information about a menu item.
typedef struct tagMENUITEMINFO {
UINT cbSize;
UINT fMask;
UINT fType;
UINT fState;
UINT wID;
HMENU hSubMenu;
HBITMAP hbmpChecked;
HBITMAP hbmpUnchecked;
DWORD dwItemData;
LPTSTR dwTypeData;
UINT cch;
} MENUITEMINFO, FAR *LPMENUITEMINFO;
Members
cbsize
Size of structure, in bytes.
fMask
Members to retrieve or set. This member can be one or more of these values:
Value | Meaning |
MIIM_CHECKMARKS | Retrieves or sets the hbmpChecked and hbmpUnchecked members. |
MIIM_DATA | Retrieves or sets the dwItemData member. |
MIIM_ID | Retrieves or sets the wID member. |
MIIM_STATE | Retrieves or sets the fState member. |
MIIM_SUBMENU | Retrieves or sets the hSubMenu member. |
MIIM_TYPE | Retrieves or sets the fType and dwTypeData members. |
fType
Menu item type. This member can be one or more of these values:
Value | Meaning |
MFT_BITMAP | Displays the menu item using a bitmap. The low-order word of the dwTypeData member is the bitmap handle, and the cch member is ignored. |
MFT_MENUBARBREAK | Places the menu item on a new line (for a menu bar) or in a new column (for a drop-down menu, submenu, or shortcut menu). For a drop-down menu, submenu, or shortcut menu, a vertical line separates the new column from the old. |
MFT_MENUBREAK | Places the menu item on a new line (for a menu bar) or in a new column (for a drop-down menu, submenu, or shortcut menu). For a drop-down menu, submenu, or shortcut menu, the columns are not separated by a vertical line. |
MFT_OWNERDRAW | Assigns responsibility for drawing the menu item to the window that owns the menu. The window receives a WM_MEASUREITEM message before the menu is displayed for the first time, and a WM_DRAWITEM message whenever the appearance of the menu item must be updated. If this value is specified, the dwTypeData member contains an application-defined 32-bit value. |
MFT_RADIOCHECK | Displays checked menu items using a radio-button mark instead of a check mark if the hbmpChecked member is NULL. |
MFT_RIGHTJUSTIFY | Right-justifies the menu item and any subsequent items. This value is valid only if the menu item is in a menu bar. |
MFT_SEPARATOR | Specifies that the menu item is a separator. A menu item separator appears as a horizontal dividing line. The dwTypeData and cch members are ignored. This value is valid only in a drop-down menu, submenu, or shortcut menu. |
MFT_STRING | Displays the menu item using a text string. The dwTypeData member is the pointer to a null-terminated string, and the cch member is the length of the string. |
The MFT_BITMAP, MFT_SEPARATOR, and MFT_STRING values cannot be combined with one another.
fState
Menu item state. This member can be one or more of these values:
Value | Meaning |
MFS_CHECKED | Checks the menu item. For more information about checked menu items, see the hbmpChecked member. |
MFS_DEFAULT | Specifies that the menu item is the default. A menu can contain only one default menu item, which is displayed in bold. |
MFS_DISABLED | Disables the menu item so that it cannot be selected, but does not gray it. |
MFS_ENABLED | Enables the menu item so that it can be selected. This is the default state. |
MFS_GRAYED | Disables the menu item and grays it so that it cannot be selected. |
MFS_HILITE | Highlights the menu item. |
MFS_UNCHECKED | Unchecks the menu item. For more information about unchecked menu items, see the hbmpUnchecked member. |
MFS_UNHILITE | Removes the highlight from the menu item. This is the default state. |
wID
Application-defined 16-bit value that identifies the menu item.
hSubMenu
Handle to the drop-down menu or submenu associated with the menu item. If the menu item is not an item that opens a drop-down menu or submenu, this member is NULL.
hbmpChecked
Handle to the bitmap to display next to the item if it is checked. If this member is NULL, a default bitmap is used. If the MFT_RADIOCHECK type value is specified, the default bitmap is a bullet. Otherwise, it is a check mark.
hbmpUnchecked
Handle to the bitmap to display next to the item if it is not checked. If this member is NULL, no bitmap is used.
dwItemData
Application-defined value associated with the menu item.
dwTypeData
Content of the menu item. The meaning of this member depends on the menu item type: the MFT_BITMAP, MFT_SEPARATOR, or MFT_STRING values.
cch
Length of the menu item text, when information is received about a menu item of the MFT_STRING type. This value is zero for other menu item types. This member is ignored when the content of a menu item is set.
Remarks
The MENUITEMINFO structure is used with the GetMenuItemInfo, InsertMenuItem, and SetMenuItemInfo functions.
