CheckMenuRadioItem function

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 WINAPI CheckMenuRadioItem(
  _In_ HMENU hmenu,
  _In_ UINT  idFirst,
  _In_ UINT  idLast,
  _In_ UINT  idCheck,
  _In_ UINT  uFlags
);

Parameters

hmenu [in]

Type: HMENU

A handle to the menu that contains the group of menu items.

idFirst [in]

Type: UINT

The identifier or position of the first menu item in the group.

idLast [in]

Type: UINT

The identifier or position of the last menu item in the group.

idCheck [in]

Type: UINT

The identifier or position of the menu item to check.

uFlags [in]

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.
