MenuCheck |
Function (ROM Call 0x37) |
Checks/unchecks or returns the state of an item in a pulldown menu.
MenuCheck checks/unchecks or returns the state of the check mark of the pulldown submenu item identified by ID
(see MenuAddText for more details about item IDs).
ExecHandle is a handle returned from the MenuBegin function,
not from MenuNew.
If Cmd is set to MC_STATUS, MenuCheck returns the status of the check mark (zero: not checked, nonzero: checked).
Otherwise it returns TRUE on success (i.e. item was found) and FALSE on failure.
The Cmd parameter must be one of the following values, defined in the enum MenuCheckCmds:
MC_CHECK |

MC_UNCHECK |
AMS 2.00 or higher: Remove the check mark. |
MC_STATUS |
