Struct MacLevelIndicator 

pub struct MacLevelIndicator<'a> { /* private fields */ }

Authentic macOS AppKit signal and audio level meter (NSLevelIndicator equivalent).

Example

use egui_macview::{MacLevelIndicator, MacLevelIndicatorStyle, MacTheme};

let theme = MacTheme::default();
MacLevelIndicator::new(-12.0, -60.0..=0.0)
    .theme(&theme)
    .warning_value(-18.0)
    .critical_value(-6.0)
    .peak_hold(-3.0)
    .style(MacLevelIndicatorStyle::Discrete)
    .show(ui);

Implementations

impl<'a> MacLevelIndicator<'a>

pub fn new(value: f32, range: RangeInclusive<f32>) -> Self

Creates a new level indicator for value within range.

pub fn warning_value(self, warning: f32) -> Self

Sets warning threshold where meter switches from green to yellow/amber.

pub fn critical_value(self, critical: f32) -> Self

Sets critical threshold where meter switches from yellow/amber to red.

pub fn peak_hold(self, peak: f32) -> Self

Sets optional peak-hold marker value.

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

Sets meter style (Continuous or Discrete).

pub fn orientation(self, orientation: MacLevelOrientation) -> Self

Sets meter orientation (Horizontal or Vertical).

pub fn segments(self, count: usize) -> Self

Sets discrete segment count.

pub fn segmented_threshold_colors(self, enabled: bool) -> Self

Enables per-segment VU meter threshold coloring instead of uniform AppKit discrete capacity color.

pub fn tick_marks(self, count: usize) -> Self

Sets the number of graduation tick marks rendered along the meter axis.

pub fn length(self, length: f32) -> Self

Overrides primary-axis length in points.

pub fn thickness(self, thickness: f32) -> Self

Overrides cross-axis thickness in points.

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

Enables or disables the control.

pub fn theme(self, theme: &'a MacTheme) -> Self

Injects dynamic MacTheme.

pub fn color_for_value(&self, theme: &MacTheme, sample_value: f32) -> Color32

Evaluates the semantic AppKit meter color for a given sample level sample_value.

pub fn show(self, ui: &mut Ui) -> Response

Renders the level indicator in ui.

Trait Implementations

impl<'a> Widget for MacLevelIndicator<'a>

fn ui(self, ui: &mut Ui) -> Response

Allocate space, interact, paint, and return a Response.

fn boxed<'a>(self) -> Box<dyn FnOnce(&mut Ui) -> Response + 'a>

where Self: Sized + 'a,

Box this widget for dynamic dispatch.
