CheckMenuRadioItem function (winuser.h)
Checks a specified menu item and makes it a radio item. At the same time, the function clears all other menu items in the associated group and clears the radio-item type flag for those items.
Syntax
BOOL CheckMenuRadioItem(
[in] HMENU hmenu,
[in] UINT first,
[in] UINT last,
[in] UINT check,
[in] UINT flags
);
Parameters
[in] hmenu
Type: HMENU
A handle to the menu that contains the group of menu items.
[in] first
Type: UINT
The identifier or position of the first menu item in the group.
[in] last
Type: UINT
The identifier or position of the last menu item in the group.
[in] check
Type: UINT
The identifier or position of the menu item to check.
[in] flags
Type: UINT
Indicates 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 value
Type: BOOL
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 selected 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.
