Graphics.UI.WxGeneric.GenericWidget

Contains GenWid, which is the type used for the inner widget in WxGeneric. Plus functions to create GenWid.

GenWid contains a valued version of Composite.

Documentation

valuedCompose :: (Parms (CPanel ()) -> IO (Layout, IO a, a -> IO (), IO (IO ()), IO () -> IO (), IO WidTree)) -> GenWidIO a

Composing multiple widgets into a composite GenWid. It is similar to compose.

mkGenWid :: forall w a. Window w -> IO a -> (a -> IO ()) -> IO (IO ()) -> (IO () -> IO ()) -> IO WidTree -> GenWid a

Creates a GenWid using monadic actions.

mkSingleObservable :: forall w a. Observable (Window w) => Window w -> IO a -> (a -> IO ()) -> IO WidTree -> GenWid a

Creates a GenWid using an Observable widget, a get-value action and a set-value action.

mkSingleObservableEx :: forall w a. Observable (Window w) => Window w -> (Layout -> Layout) -> IO a -> (a -> IO ()) -> IO WidTree -> GenWid a

Creates a GenWid using an Observable widget, a get-value action and a set-value action.

type GenWidIO a = forall w. Parms w -> IO (GenWid a)

class MapValue valued where

Methods

mapValue

Arguments

:: (old -> new)

old to new conversion

-> (old -> new -> old)

new to old conversion. This functions also get the current old value as input.

-> valued old

old type

-> valued new

new type

Maps the value a type.

Instances

MapValue GenWid

MapValue Outer

data Parms w

subParms :: Parms w -> Parms w

When a GenWid has sub-GenWid use this function to update GenWidParms.

Currently, only GenericClass.singleConstr uses this function. But, in principle, it should be called by functions using sub-widget.

getParent :: Parms w -> Window w

Use this parent when constructing new widgets.

setParent :: Window w -> Parms w' -> Parms w

getJoinLayout :: Parms w -> JoinLayout

transformLabel :: Parms w -> String -> IO String

Initial parameters

data GenWidParameters

Constructors

GenWidParameters

Fields

joinLayout :: JoinLayout

labelTransform :: TransformLabel

defaultParms :: (GenWidParameters -> GenWidParameters) -> GenWidParameters

toParms :: Window w -> GenWidParameters -> IO (Parms w)

Initial parameters. Should only be called at the top-level. If already in a GenWid function then use subParms.

Labels

data TransformLabel

mkTransformLabel :: s -> (String -> State s String) -> TransformLabel

idLabel :: TransformLabel

greedyShortcuts :: [Char] -> TransformLabel

data WidTree

data WxWindow

Constructors

forall w . WxWindow (Window w)

class WidgetTree w where

Methods

widgetTree :: ReadAttr w WidTree

Get all wxHaskell widgets (Window w) which are inputable. That is, we get widgets like text-entries and slides, but not widgets like labels.

Instances

WidgetTree (GenWid a)

WidTree constructors

mkWidTree :: [WxWindow] -> [WidTree] -> WidTree

Construct WidTree

singleChild :: Window w -> IO WidTree

Construct WidTree from a single WxHaskell widget.

leafWidTree :: [WxWindow] -> IO WidTree

Construct WidTree leaf node.

Update/get ops

getChildren :: WidTree -> [WxWindow]

updateChildren :: Update [WxWindow] -> Update WidTree

getSubTrees :: WidTree -> [WidTree]

updateSubTrees :: Update [WidTree] -> Update WidTree

Traversal

depthFirstTraversal :: WidTree -> [Window ()]

Depth first traversal of WidTree FIXME: Is not really, or atleast do not seem like a depth first traversal to the the user of WxGeneric.
