Constructor

widgetCustom :: Rectangle -> Maybe String -> CustomWidgetFuncs Widget -> IO (Ref Widget)

widgetMaker

Arguments

:: Parent a Widget

=> Rectangle

Position and size

-> Maybe String

Title

-> Maybe (CustomWidgetFuncs a)

Custom functions

-> (Int -> Int -> Int -> Int -> IO (Ptr ()))

Foreign constructor to call if neither title nor custom functions are given

-> (Int -> Int -> Int -> Int -> String -> IO (Ptr ()))

Foreign constructor to call if only title is given

-> (Int -> Int -> Int -> Int -> Ptr () -> IO (Ptr ()))

Foreign constructor to call if only custom functions are given

-> (Int -> Int -> Int -> Int -> String -> Ptr () -> IO (Ptr ()))

Foreign constructor to call if both title and custom functions are given

-> IO (Ref a)

Reference to the widget

Lots of Widget subclasses have the same constructor parameters. This function consolidates them.

Only of interest to Widget contributors.

defaultCustomWidgetFuncs :: forall a. Parent a Widget => CustomWidgetFuncs a

An empty set of functions to pass to widgetCustom.

fillCustomWidgetFunctionStruct :: forall a. Parent a Widget => Ptr () -> CustomWidgetFuncs a -> IO ()

Fill up a struct with pointers to functions on the Haskell side that will get called instead of the default ones.

Fill up the Widget part the function pointer struct.

customWidgetFunctionStruct :: forall a. Parent a Widget => CustomWidgetFuncs a -> IO (Ptr ())

Given a record of functions, return a pointer to a struct with function pointers back to those functions.
