GI.Gtk.Declarative.Markup

Contents

Description

MarkupOf is the common builder type for the (declarative) GTK+ markup language, supporting do syntax. MarkupOf wraps many widgets, usually of type Widget, but they can be of other types.

A Widget value can wrap any Patchable widget, hiding the underlying widget type, such that you can embed heterogeneous collections of widgets in containers.

Synopsis

Documentation

data Widget event where Source #

A Widget value wraps a Patchable and EventSource widget, providing a constrained equivalent of a Dynamic value. It is used to support heterogeneous containers of widgets, and to support equality checks on different types of widgets when calculating patches.

Constructors

Widget :: (Typeable widget, Patchable widget, Functor widget, EventSource widget) => widget event -> Widget event 
Instances
Functor Widget Source # 
Instance details

Defined in GI.Gtk.Declarative.Markup

Methods

fmap :: (a -> b) -> Widget a -> Widget b #

(<$) :: a -> Widget b -> Widget a #

Patchable Widget Source #

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

Methods

fromWidget :: Container widget children event -> Markup event a Source #

Markup

data MarkupOf widget event a Source #

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.

Methods

fromWidget :: Container widget children event -> MarkupOf (Container widget children) event a Source #

type Markup event a = MarkupOf Widget event a Source #

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

single :: widget event -> MarkupOf widget event () Source #

Construct markup from a single widget.

multiple :: Vector (widget event) -> MarkupOf widget event () Source #

Construct markup from multiple widgets.

runMarkup :: MarkupOf widget event () -> Vector (widget event) Source #

Run a MarkupOf builder and get its widgets.

Widget to Markup conversion

class FromWidget widget event target | target -> event where Source #

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.
