ToggleButton Interface description

A button is an instance of the more general Toggle abstraction, so operations allowed on Toggles all apply to buttons:

toggleButton :: Picture -> Picture -> Component (Toggle Bool, DisplayHandle)

create a flip-flop toggle button with arbitrary labels for the on and off state. Each time the toggle is clicked, the Toggle will emit a boolean value to indicate its pressed state

getToggleClick :: Toggle a -> IO a

get the current state of the toggle.

waitToggleClick :: Toggle a -> IO a

block until the toggle state changes.

setToggleLabel :: Toggle a -> Bool -> Picture -> IO a

change the current label for the toggle.

combineToggles :: [Toggle a] -> IO (Toggle [a])

merge a set of toggles together, such that clicks that are reported to any of the component toggles are forwarded to the combined toggle.

mapToggle :: (a->b) -> (b->a) -> Toggle a -> Toggle b

mapIOToggle :: (a-> IO b) -> (b->a) -> Toggle a -> Toggle b

returns a new toggle that for every value output by an existing button apply a function to its output.

disableToggle :: Toggle a -> IO ()

enableToggle :: Toggle a -> IO ()

disable or enable interaction with the user.

setToggleName :: ToggleName -> Toggle a -> Toggle a

return the toggle value with a new name associated with it.
