CheckMenuRadioItem info  Overview  Group

The CheckMenuRadioItem function checks a specified menu item and makes it a radio item. At the same time, the function unchecks all other menu items in the associated group and clears the radio-item type flag for those items.

BOOL CheckMenuRadioItem(

HMENU hmenu,
UINT idFirst,
UINT idLast,
UINT idCheck,
UINT uFlags
);

Parameters

hmenu

Handle to the menu that contains the group of menu items.

idFirst 

Identifier or position of the first menu item in the group.

idLast

Identifier or position of the last menu item in the group.

idCheck

Identifier or position of the menu item to check.

uFlags

Value specifying the meaning of idFirst, idLast, and idCheck. If this parameter is MF_BYCOMMAND, the other parameters specify menu item identifiers. If it is MF_BYPOSITION, the other parameters specify the menu item positions.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, use the GetLastError function.

Remarks

The CheckMenuRadioItem function sets the MFT_RADIOCHECK type flag and the MFS_CHECKED state for the item specified by idCheck and, at the same time, clears both flags for all other items in the group. The checked item is displayed using a bullet bitmap instead of a check-mark bitmap.

For more information about menu item type and state flags, see the MENUITEMINFO structure.
