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;
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. |
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.
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. |
The MENUITEMINFO structure is used with the GetMenuItemInfo, InsertMenuItem, and SetMenuItemInfo functions.
