A trait implemented for GTK4 widgets that allows a factory to create and remove widgets.

Required Associated Types

type ReturnedWidget: Debug + Hash

The widget returned when inserting a widget.

This doesn’t matter on containers like gtk::Box. However, widgets such as gtk::Stack return a gtk::StackPage which might be used to set additional parameters.

Therefore, this “returned widget” is explicitly handled here.

type Children: Debug + AsRef<Self::Children>

Widget type that is attached to the container and also the root of the components.

type Position

Position type used by this widget.

For example GridPosition for gtk::Grid or () for gtk::Box

Required Methods

fn factory_remove(&self, widget: &Self::ReturnedWidget)

Removes a widget.

fn factory_append( &self, widget: impl AsRef<Self::Children>, position: &Self::Position, ) -> Self::ReturnedWidget

Adds a new widget to self at the end.

fn factory_prepend( &self, widget: impl AsRef<Self::Children>, position: &Self::Position, ) -> Self::ReturnedWidget

Add an widget to the front.

fn factory_insert_after( &self, widget: impl AsRef<Self::Children>, position: &Self::Position, other: &Self::ReturnedWidget, ) -> Self::ReturnedWidget

Insert a widget after another widget.

fn returned_widget_to_child(root_child: &Self::ReturnedWidget) -> Self::Children

Converts a returned widget to the children type.

fn factory_move_after( &self, widget: &Self::ReturnedWidget, other: &Self::ReturnedWidget, )

Move an item after another item.

fn factory_move_start(&self, widget: &Self::ReturnedWidget)

Move an item to the start.

Provided Methods

fn factory_update_position( &self, _widget: &Self::ReturnedWidget, _position: &Self::Position, )

Update the position inside positioned containers like gtk::Grid.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
