Struct SimpleComboRow 

pub struct SimpleComboRow<E: ToString> {
    pub variants: Vec<E>,
    pub active_index: Option<usize>,
}

Available on crate feature libadwaita only.

A simple wrapper around adw::ComboRow.

This can be used with enums, Strings or any custom type you want. The only requirement is that the inner type implements ToString and Debug.

To get notified when the selection changed, you can use Connector::forward() after launching the component.

Fields

variants: Vec<E>

The variants that can be selected.

active_index: Option<usize>

The index of the active element or None is nothing is selected.

Implementations

impl<E> SimpleComboRow<E>

where E: ToString,

pub fn get_active_elem(&self) -> Option<&E>

Return the value of the currently selected element or None if nothing is selected.

Trait Implementations

impl<E: Clone + ToString> Clone for SimpleComboRow<E>

fn clone(&self) -> SimpleComboRow<E>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<E> Component for SimpleComboRow<E>

where E: ToString + 'static + Debug,

type CommandOutput = ()

Messages which are received from commands executing in the background.

type Input = SimpleComboRowMsg<E>

The message type that the component accepts as inputs.

type Output = usize

The message type that the component provides as outputs.

type Init = SimpleComboRow<E>

The parameter used to initialize the component.

type Root = ComboRow

The top-level widget of the component.

type Widgets = ComboRow

The type that’s used for storing widgets created for this component.

fn init_root() -> Self::Root

Initializes the root widget.

fn init( model: Self::Init, widgets: Self::Root, sender: ComponentSender<Self>, ) -> ComponentParts<Self>

Creates the initial model and view, docking it into the component.

fn update_with_view( &mut self, widgets: &mut Self::Widgets, input: Self::Input, sender: ComponentSender<Self>, _root: &Self::Root, )

Updates the model and view when a new input is received.

fn builder() -> ComponentBuilder<Self>

Create a builder for this component.

fn update( &mut self, message: Self::Input, sender: ComponentSender<Self>, root: &Self::Root, )

Processes inputs received by the component.

fn update_cmd( &mut self, message: Self::CommandOutput, sender: ComponentSender<Self>, root: &Self::Root, )

Defines how the component should respond to command updates.

fn update_cmd_with_view( &mut self, widgets: &mut Self::Widgets, message: Self::CommandOutput, sender: ComponentSender<Self>, root: &Self::Root, )

Updates the model and view upon completion of a command.

fn update_view( &self, widgets: &mut Self::Widgets, sender: ComponentSender<Self>, )

Updates the view after the model has been updated.

fn shutdown( &mut self, widgets: &mut Self::Widgets, output: Sender<Self::Output>, )

Last method called before a component is shut down.

fn id(&self) -> String

An identifier for the component used for debug logging.

impl<E: Debug + ToString> Debug for SimpleComboRow<E>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<E: PartialEq + ToString> PartialEq for SimpleComboRow<E>

fn eq(&self, other: &SimpleComboRow<E>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
