Struct Switch 

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

An on/off switch that applies at once, with an optional label.

The knob steps one cell every motion.step, and the track and knob colours blend with each step; the knob is always the brightest part. Enter, Space or a click toggles it. The application owns the state.

Style keys: switch (track, track-on, knob, knob-on) and switch-labeled (bg, fg, dot) with states hover, focus, checked, disabled; switch-label (fg). The labeled style reads its words from quvyta.switch.on and quvyta.switch.off.

Implementations

impl<Msg> Switch<Msg>

pub fn new(on: bool) -> Self

A capsule switch showing on.

pub fn label(self, label: impl Into<String>) -> Self

Text after the switch; clicking it toggles too.

pub fn style(self, style: SwitchStyle) -> Self

Chooses how the switch looks.

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

Greys the switch out; it cannot be focused or toggled.

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

Message for the new state when the switch is toggled.

Trait Implementations

impl<Msg: 'static> Widget<Msg> for Switch<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.
