A source item in the object tree (indicator or drawing)

Represents a single row in the Object Tree with all its properties and state for UI rendering.

Fields

id: usize

Unique identifier

series_id: Option<SeriesId>

Chart series id used by ObjectTreePanel::apply_to_chart; drawing rows use id.

source_type: SourceType

Source type (indicator, drawing, template)

tool_type: Option<DrawingToolType>

For drawings: the tool type

name: String

Display name (e.g., “Trend Line”, “SMA(20)”)

label: Option<String>

User-defined label (overrides name if set)

color: Color32

Primary color for display

visible: bool

Is visible on chart

locked: bool

Is locked (drawings only - prevents modification)

selected: bool

Is selected in the tree

expanded: bool

Is expanded (shows properties)

z_index: i32

Z-index for rendering order

properties: Option<DrawingProperties>

Drawing properties (for drawings only)

parameters: Option<String>

Indicator parameters string (for indicators, e.g., “20, close”)

panes: Vec<(PaneId, String)>

Panes a drawing row’s Move to menu offers, by stable id and title; empty leaves it out.

folder: Vec<String>

Drawing folder path, copied from crate::drawings::Drawing::folder. Non-drawing rows ignore this field.

Implementations

impl SourceItem

Arguments

• id - Unique identifier
• name - Data source name (e.g., “BTCUSDT · 1H”)

pub fn with_series_id(self, id: SeriesId) -> Self

Bind a data-source or indicator row to its chart series without overloading the tree’s ids.

pub fn with_panes(self, chart: &Chart) -> Self
