MENUITEMINFO info  Overview  Group

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.
