Synopsis

Constructor

widgetCustom Source #

Arguments

:: Rectangle	The bounds of this widget
-> Maybe String	The widget label
-> (Ref Widget -> IO ())	Custom drawing function
-> CustomWidgetFuncs Widget	Other custom functions
-> IO (Ref Widget)

widgetMaker Source #

Arguments

:: Parent a Widget
=> Rectangle	Position and size
-> Maybe String	Title
-> Maybe (Ref a -> IO ())	Custom drawing function
-> Maybe (CustomWidgetFuncs a)	Custom functions
-> (Int -> Int -> Int -> Int -> IO (C2HSImp.Ptr ()))	Foreign constructor to call if neither title nor custom functions are given
-> (Int -> Int -> Int -> Int -> String -> IO (C2HSImp.Ptr ()))	Foreign constructor to call if only title is given
-> (Int -> Int -> Int -> Int -> C2HSImp.Ptr () -> IO (C2HSImp.Ptr ()))	Foreign constructor to call if only custom functions are given
-> (Int -> Int -> Int -> Int -> String -> C2HSImp.Ptr () -> IO (C2HSImp.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 Source #

An empty set of functions to pass to widgetCustom.

fillCustomWidgetFunctionStruct :: forall a. Parent a Widget => C2HSImp.Ptr () -> Maybe (Ref a -> IO ()) -> CustomWidgetFuncs a -> IO () Source #

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.
