Struct Segmented 

pub struct Segmented<Msg> { /* private fields */ }

Side-by-side segments of one surface, of which the filled one is chosen: for two to five short, mutually exclusive choices such as a view mode, where the choice should read at a glance.

The control takes focus as one: Left and Right choose the neighbouring segment, Home and End the first and last, and a click chooses the segment under the pointer. The application owns the choice.

Style keys: segment (bg, fg, bold, padding, pillar) with states hover, focus, checked, disabled. The pillar stands in the first cell of the hovered segment, or of the chosen one while the keyboard focuses the control.

Implementations

impl<Msg> Segmented<Msg>

pub fn new(options: impl IntoIterator<Item = impl Into<String>>) -> Self

Segments for options with the first chosen.

pub fn selected(self, index: usize) -> Self

The chosen segment.

pub fn disabled(self, disabled: bool) -> Self

Greys the control out; it cannot be focused or changed.

pub fn on_select(self, message: impl Fn(usize) -> Msg + 'static) -> Self

Message for choosing segment index.

Trait Implementations

impl<Msg: 'static> Widget<Msg> for Segmented<Msg>

fn measure(&self, cx: &mut MeasureCx<'_>, available: Size) -> Size

The size the widget wants when it may use up to available.

fn paint(&self, cx: &mut PaintCx<'_>, area: Rect)

Draws the widget into area.

fn event(&self, cx: &mut EventCx<'_, Msg>, event: &Event) -> bool

Handles input. Returns true when the event was used; unused key and scroll events bubble to the parent widget.

fn focusable(&self) -> bool

Whether the widget can take keyboard focus.

fn paint_overlay(&self, _cx: &mut PaintCx<'_>, _anchor: Rect)

Draws the widget’s overlay after the whole view was painted, when it asked for one with PaintCx::request_overlay. anchor is the area the widget was painted in.

fn children(&self) -> &[Node<Msg>]

Child nodes, for widgets that contain other widgets.

fn children_mut(&mut self) -> &mut [Node<Msg>]

Mutable child nodes, used to assign ids.
