Struct WidgetBar 

pub struct WidgetBar {
    pub config: WidgetBarConfig,
    pub icons: Vec<RightBarIcon>,
    pub active_icon: Option<RightBarIcon>,
    pub widgets: Vec<WidgetBarWidget>,
    pub active_widget: Option<u64>,
    pub notification_counts: HashMap<RightBarIcon, u32>,
    /* private fields */
}

Right Edge Icon Bar

Fields

config: WidgetBarConfig

Display and layout options for this component.

icons: Vec<RightBarIcon>

Built-in entries shown, drawn in RightBarIcon order.

active_icon: Option<RightBarIcon>

Currently open built-in panel. Clicks toggle this value; the host must keep it in step with panels opened or closed elsewhere before calling show.

widgets: Vec<WidgetBarWidget>

Host widget entries, empty until the host supplies them.

active_widget: Option<u64>

Active host widget. Selecting a built-in entry clears it, and vice versa.

notification_counts: HashMap<RightBarIcon, u32>

Badge counts keyed by built-in bar entry.

Implementations

impl WidgetBar

pub fn new() -> Self

Create a WidgetBar with default settings.

pub fn with_config(self, config: WidgetBarConfig) -> Self

Use the supplied display and layout options.

pub fn register_panel( &mut self, widget: WidgetBarWidget, content: impl FnMut(&mut Ui) + 'static, )

Register a host panel, using the widget tooltip as its title and accessible name.

Replacing an existing id preserves its position in the strip and its active state. The callback may capture host state and runs only while this panel is open. Call Self::show_panel after Self::show and before the central chart panel. Hosts own the contents, data sources and persistence.

use egui_charts::icons::icons;
use egui_charts::ui::widget_bar::{WidgetBar, WidgetBarSection, WidgetBarWidget};
let mut bar = WidgetBar::new();
let mut notes = String::new();
bar.register_panel(WidgetBarWidget {
    id: 42, icon: icons::WATCHLIST, tooltip: "Session notes".into(),
    section: WidgetBarSection::Top,
}, move |ui| { ui.text_edit_multiline(&mut notes); });
// In each frame: bar.show(rail_ui); bar.show_panel(root_ui); then show the chart.

pub fn show_panel(&mut self, ui: &mut Ui)

Show the active registered panel beside the strip, with a themed title and close button.

Clicking the same strip entry or the close button closes it. Built-in selections clear the active host panel. Widget entries without a registered callback remain host-rendered. Panel width is resizable and retained by egui under the widget’s stable id.

pub fn set_control_visible(&mut self, control: Control, visible: bool)

Shows or hides Alerts, ObjectTree or Help and clears a hidden active entry. Other controls are ignored. Hosts close any corresponding panel they render.

pub fn set_notification_cnt(&mut self, icon: RightBarIcon, count: u32)

Set the badge count for a built-in bar entry.

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

Show the bar, keeping the bottom section at the foot and scrolling if it cannot fit. Host widget clicks return their id; the host owns the corresponding panel contents.

Trait Implementations

impl Default for WidgetBar

fn default() -> Self

Returns the “default value” for a type.
