GI.Gtk.Declarative

The declarative layer on top of GTK+ lets you describe your user interface as a declarative hierarchy of objects, using data structures and pure functions. You can leverage the declarative event handling to build reusable widgets. The Patch typeclass, and the instances provided by this library, performs minimal updates to GTK+ widgets using the underlying imperative operations, so that your rendering can always be a pure function your state to a Widget.

data EventHandler gtkEventHandler widget (purity :: Purity) event where

Encodes the user event handler in such a way that we can have a Functor instance for arity-polymorphic event handlers.

Constructors

PureEventHandler :: EventHandlerReturn Identity ret e -> EventHandler (IO ret) w Pure e

ImpureEventHandler :: (w -> EventHandlerReturn IO ret e) -> EventHandler (IO ret) w Impure e

EventHandlerFunction :: (a -> EventHandler b w p e) -> EventHandler (a -> b) w p e

Instances

Functor (EventHandler gtkEventHandler widget purity)

Defined in GI.Gtk.Declarative.Attributes.Internal.EventHandler

Methods

fmap :: (a -> b) -> EventHandler gtkEventHandler widget purity a -> EventHandler gtkEventHandler widget purity b

(<$) :: a -> EventHandler gtkEventHandler widget purity b -> EventHandler gtkEventHandler widget purity a

type ClassSet = HashSet Text

A set of CSS classes.

data Attribute widget event where

The attribute GADT represent a supported attribute for a declarative widget. This extends the regular notion of GTK+ attributes to also include event handling and CSS classes.

Constructors

(:=) :: (AttrOpAllowed AttrConstruct info widget, AttrOpAllowed AttrSet info widget, AttrGetC info widget attr getValue, AttrSetTypeConstraint info setValue, KnownSymbol attr, Typeable attr, Eq setValue, Typeable setValue) => AttrLabelProxy (attr :: Symbol) -> setValue -> Attribute widget event

An attribute/value mapping for a declarative widget. The AttrLabelProxy is parameterized by attr, which represents the GTK-defined attribute name. The underlying GI object needs to support the construct, get, and set operations for the given attribute.

Classes :: IsWidget widget => ClassSet -> Attribute widget event

Defines a set of CSS classes for the underlying widget's style context. Use the classes function instead of this constructor directly.

OnSignalPure :: (GObject widget, SignalInfo info, gtkCallback ~ HaskellCallbackType info, ToGtkCallback gtkCallback Pure) => SignalProxy widget info -> EventHandler gtkCallback widget Pure event -> Attribute widget event

Emit events using a pure event handler. Use the on function, instead of this constructor directly.

OnSignalImpure :: (GObject widget, SignalInfo info, gtkCallback ~ HaskellCallbackType info, ToGtkCallback gtkCallback Impure) => SignalProxy widget info -> EventHandler gtkCallback widget Impure event -> Attribute widget event

Emit events using a pure event handler. Use the on function, instead of this constructor directly.

AfterCreated :: (widget -> IO ()) -> Attribute widget event

Provide a callback to modify the widget after it's been created.

Instances

Functor (Attribute widget)

Attributes have a Functor instance that maps events in all event handler.

Defined in GI.Gtk.Declarative.Attributes

Methods

fmap :: (a -> b) -> Attribute widget a -> Attribute widget b

(<$) :: a -> Attribute widget b -> Attribute widget a

classes :: IsWidget widget => [Text] -> Attribute widget event

Define the CSS classes for the underlying widget's style context. For these classes to have any effect, this requires a CssProvider with CSS files loaded, to be added to the GDK screen. You probably want to do this in your entry point when setting up GTK.

on :: (GObject widget, SignalInfo info, gtkCallback ~ HaskellCallbackType info, ToGtkCallback gtkCallback Pure, ToEventHandler gtkCallback widget Pure, userEventHandler ~ UserEventHandler gtkCallback widget Pure event) => SignalProxy widget info -> userEventHandler -> Attribute widget event

Emit events, using a pure event handler, by subcribing to the specified signal.

onM :: (GObject widget, SignalInfo info, gtkCallback ~ HaskellCallbackType info, ToGtkCallback gtkCallback Impure, ToEventHandler gtkCallback widget Impure, userEventHandler ~ UserEventHandler gtkCallback widget Impure event) => SignalProxy widget info -> userEventHandler -> Attribute widget event

Emit events, using an impure event handler receiving the widget and returning an IO action of event, by subcribing to the specified signal.

afterCreated :: (widget -> IO ()) -> Attribute widget event

Provide a EventHandler to modify the widget after it's been created.

class Patchable widget where

A patchable widget is one that can create an underlying GTK widget, or calculate a Patch to be applied to an existing GTK widget that was previously created.

Minimal complete definition

create, patch

Methods

create :: widget e -> IO SomeState

Given a declarative widget that is Patchable, return an IO action that can create a new corresponding Widget. The created widget should be use in corresponding patch modifications, until it is replaced.

patch :: SomeState -> widget e1 -> widget e2 -> Patch

Given two declarative widgets of the same widget type (but not necessarily of the same event types,) calculate a Patch.

Instances

Widget is itself patchable, by delegating to the underlying widget instances.

Methods

patch :: SomeState -> Container container (Children child) e1 -> Container container (Children child) e2 -> Patch

data Patch

A possible action to take on an existing Widget, decided by the patch method when comparing declarative widgets.

Constructors

Modify (IO SomeState)

An IO action to apply to a Widget to make it reflect an updated declarative widget. The action to apply is calculated from the difference between the old and the new declarative widget.

Replace (IO SomeState)

Replace the current Widget by the widget returned by the IO action.

Keep

Do nothing, i.e. keep the Widget as it is.

class FromWidget widget event target | target -> event where

Convert a widget to a target type. This is deliberately unconstrained in it's types, and is used by smart constructors to implement return type polymorphism, so that a smart contructor can return either a Widget, or some specifically typed MarkupOf, depending on the context in which it's used.

type Markup event a = MarkupOf Widget event a

Handy type alias for the common case of markup containing Widgets.

data MarkupOf widget event a

The declarative markup builder, primarily for using its Monad instance and do notation to construct adjacent widgets in containers.

It is parameterized with widget and event, such that containers can restrict the type of their children to other types than Widget.

Note that the return type, a, is not used in this library. It's a more a technical necessity to have the Monad instance. You can still use it if you need to return a value from a markup function, though.
