Using the package ghc682-gtk2hs - 0.9.12.1-6.fc8.i386 for Fedora 8, the field

toggleActionIsActive

is not changed when the user checks or unchecks a menu item.

data ToggleActionEntry = ToggleActionEntry {
toggleActionName :: String
toggleActionLabel :: String
toggleActionStockId :: (Maybe String)
toggleActionAccelerator :: (Maybe String)
toggleActionTooltip :: (Maybe String)
toggleActionCallback :: (IO ())
toggleActionIsActive :: Bool
}

There is a workaround, because the toggleActionCallback function does work when the user checks or unchecks an item. This can be used to set or unset an IORef. Example:

myTog :: IORef Bool -> IO ()
myTog chk = do old <- readIORef chk
               writeIORef chk (not old)

in:

duptogg = ToggleActionEntry "DupCheck" "Check Data" (Just stockConvert) Nothing 
                             (Just "Check facts for duplicates") (myTog dupcheck) True

On:

data RadioActionEntry = RadioActionEntry {
radioActionName :: String
radioActionLabel :: String
radioActionStockId :: (Maybe String)
radioActionAccelerator :: (Maybe String)
radioActionTooltip :: (Maybe String)
radioActionValue :: Int
}

the function:

actionGroupAddRadioActions :: 
              ActionGroup -> [RadioActionEntry] -> Int -> (RadioAction -> IO ()) -> IO ()

does not initialize to the 3rd (Int) argument as it should. The last item in the list is always initialized visually, regardless of the argument's value. The function:

radioActionGetCurrentValue 

is defined as:

radioActionGetCurrentValue
:: RadioActionClass self	
=> self	
-> IO Int

but GHCi complains there is no instance for a

RadioActionEntry type. 

However, the function can be used inside the callback function (4th argument) to get the current value.
