Struct Component 

pub struct Component { /* private fields */ }

Main relm component of the application

Most importantly implements relm::Widget as an UI application. See Component::view for initialization code.

Trait Implementations

impl Update for Component

type Model = ViewModel

The type of the model.

type ModelParam = ()

The type of the parameter of the model() function used to initialize the model.

type Msg = Msg

The type of the messages sent to the update() method.

fn model(_relm: &Relm<Self>, _model: Self::ModelParam) -> Self::Model

Create the initial model.

fn update(&mut self, event: Msg)

Method called when a message is received from an event.

fn subscriptions(&mut self, _relm: &Relm<Self>)

Connect the subscriptions. Subscriptions are Future/Stream that are spawn when the object is created.

impl Widget for Component

type Root = ApplicationWindow

The type of the root widget.

fn root(&self) -> Self::Root

Get the root widget of the view.

fn view(relm: &Relm<Self>, model: Self::Model) -> Self

Create the initial view.

fn init_view(&mut self)

Update the view after it is initially created. This method is only useful when using the #[widget] attribute, because when not using it, you can use the view() method instead.

fn on_add<W>(&self, _parent: W)

where W: IsA<Widget> + IsA<Object>,

Method called when the widget is added to its parent. This is currently only used to set the child properties of a widget as relm widget could have child properties and we don’t know its parent when it is defined. Thus, we call on_add() when it is added to its parent to set the child properties.

fn parent_id() -> Option<&'static str>

Get the parent ID. This is useful for custom Container implementation: when you implement the Container::add_widget(), you might want to insert widgets elsewhere depending of this id.

fn run(model_param: Self::ModelParam) -> Result<(), BoolError>

where Self: 'static,

Create the window from this widget and start the main loop.
