Struct ObjectTreePanel 

pub struct ObjectTreePanel { /* private fields */ }

Object Tree panel widget

Complete object management panel with:

• Data Window (OHLCV at cursor)
• Hierarchical source tree (indicators, drawings)
• Full object management (visibility, lock, delete, etc.)
• Multi-selection and keyboard shortcuts
• Context menu with all options

Example

use egui_charts::ui::widget_bar::panels::object_tree::{ObjectTreePanel, SourceItem};

let mut panel = ObjectTreePanel::new();
let mut sources = vec![
    SourceItem::indicator(1, "SMA(20)", egui::Color32::YELLOW),
];

let action = panel.show(ui, None, &mut sources);

Implementations

impl ObjectTreePanel

pub fn apply_to_chart( &mut self, chart: &mut Chart, action: &ObjectTreeAction, sources: &[SourceItem], ) -> bool

Apply a tree action to a chart. Drawing rows use drawing ids; study rows bind their chart series through SourceItem::with_series_id. Call this after Self::show.

Bind the main data source with with_series_id(SeriesId::MAIN) to control its visibility. Returns false for host-owned property dialogs, colour gestures, templates, main-series removal and renaming non-drawing rows. Drawing names are saved and undone with the drawing. Bulk actions apply to every selected drawing and study, and visibility includes the main series.
