Provided methods

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: IsA<Widget> + IsA<Object>>(&self, _parent: W)

Method called when the widget is added to its parent.

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<(), ()> where
    Self: 'static, 

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