Description

UIs as applicative functors. This module is a very simple layering over Graphics.UI.Phooey.Monad. It serves to hide the Source types and give an applicative feel to UI construction.

Synopsis

type UI = UI :. Source runUI :: UI Action -> IO () runNamedUI :: String -> UI Action -> IO () type IWidget a = a -> UI a type OWidget a = UI (Sink a) iwidget :: IWidget a -> IWidget a owidget :: OWidget' a -> OWidget a stringEntry :: IWidget String stringDisplay :: OWidget String showDisplay :: Show a => OWidget a islider :: (Int, Int) -> IWidget Int isliderDisplay :: (Int, Int) -> OWidget Int fslider :: RealFrac a => (a, a) -> IWidget a fsliderDisplay :: RealFrac a => (a, a) -> OWidget a checkBoxEntry :: IWidget Bool checkBoxDisplay :: OWidget Bool choices :: [String] -> IWidget String timedPoll :: Double -> IO a -> UI a fromTop :: Unop (UI a) fromBottom :: Unop (UI a) fromLeft :: Unop (UI a) fromRight :: Unop (UI a)

The UI applicative functor

type UI = UI :. Source Source

The UI applicative functor.

runUI :: UI Action -> IO () Source

Run a UI with window title "Applicative Phooey GUI".

runNamedUI :: String -> UI Action -> IO () Source

Run a UI with given window title.

Tools for high-level widgets

type IWidget a = a -> UI a Source

Input widget, with initial value.

type OWidget a = UI (Sink a) Source

Output widget. Yields a sink of values

iwidget :: IWidget a -> IWidget a Source

Make an input widget

owidget :: OWidget' a -> OWidget a Source

Make an output widget

Some high-level widgets

stringEntry :: IWidget String Source

String input widget

stringDisplay :: OWidget String Source

String display widget

showDisplay :: Show a => OWidget a Source

Showable output widget

islider :: (Int, Int) -> IWidget Int Source

Slider input widget

isliderDisplay :: (Int, Int) -> OWidget Int Source

Slider output widget with static bounds

fslider :: RealFrac a => (a, a) -> IWidget a Source

Slider input widget over fractional values

fsliderDisplay :: RealFrac a => (a, a) -> OWidget a Source

Slider input widget over fractional values

checkBoxEntry :: IWidget Bool Source

Boolean input widget

checkBoxDisplay :: OWidget Bool Source

Boolean display widget

choices :: [String] -> IWidget String Source

Input from a "menu" of choices.

timedPoll :: Double -> IO a -> UI a Source

Input from a timer and a means of polling. Interval is in seconds. If poll is expensive, then apply cache to the resulting UI.

Explicit layout

fromTop :: Unop (UI a) Source

Lay out from top to bottom

fromBottom :: Unop (UI a) Source

Lay out from bottom to top

fromLeft :: Unop (UI a) Source

Lay out from left to right

fromRight :: Unop (UI a) Source

Lay out from right to left
