GI.Gtk.Declarative

Description

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.

Documentation

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

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

type ClassSet = HashSet Text Source #

A set of CSS classes.

data Attribute widget event where Source #

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) Source #	Attributes have a `Functor` instance that maps events in all event handler.
Instance details 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 Source #

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 Source #

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 Source #

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 Source #

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

class Patchable widget where Source #

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.

Methods

create :: widget e -> IO SomeState Source #

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 Source #

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

Instances

Patchable Widget Source #	`Widget` is itself patchable, by delegating to the underlying widget instances.

data Patch Source #

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 target where Source #
