}

A trait that provides access to the basic properties of a component.

This trait is used to manage a component’s name, area, active state, and children.

Required Methods

fn name(&self) -> String

Returns the name of the component.

fn area(&self) -> Option<Rect>

Returns the area (Rect) of the component, if it has been set.

fn set_area(&mut self, area: Rect)

Sets the area (Rect) for the component.

fn is_active(&self) -> bool

Returns the active state of the component.

fn set_active(&mut self, active: bool)

Sets the active state of the component.

fn register_action_handler(&mut self, tx: UnboundedSender<Action>)

Registers an action handler that can send Actions for processing.

fn send(&self, action: &str)

Sends a string message through the action handler bus.

fn send_action(&self, action: Action)

Sends an Action through the action handler bus.

fn as_active(self) -> Self

where Self: Sized,

Sets the component as active on initialization (builder-pattern).

fn get_children(&mut self) -> &mut BTreeMap<String, Box<dyn Component>>

Gets all child components. This is necessary if the component has children, as it will be used by other functions to have knowledge of the children.
