Enum DrawingInteractionMode 

pub enum DrawingInteractionMode {
    SingleClick,
    ClickClick,
    DragToDraw,
    ContinuousDraw,
    MultiPoint,
    NotDrawing,
}

How a drawing tool captures points from mouse/pointer input.

Every DrawingToolType maps to exactly one interaction mode via DrawingToolType::interaction_mode(). The mode governs the full creation flow: how many clicks are needed, whether dragging is involved, and when the drawing is marked as complete.

Example

use egui_charts::config::{DrawingToolType, DrawingInteractionMode};

assert_eq!(
    DrawingToolType::TrendLine.interaction_mode(),
    DrawingInteractionMode::ClickClick,
);
assert_eq!(
    DrawingToolType::Rect.interaction_mode(),
    DrawingInteractionMode::DragToDraw,
);

Variants

SingleClick

Click once to place (e.g., HorizontalLine, TextLabel, arrow markers).

The drawing is created and completed with a single click. Only one ChartPoint is captured.

ClickClick

Click to set the first point, move, then click to set the second point (e.g., TrendLine, Ray, ExtendedLine).

A preview line follows the cursor between the first and second clicks.

DragToDraw

Press the mouse button to set the first point, drag to the second point, and release to complete (e.g., Rect, Circle, FibonacciRetracement).

ContinuousDraw

Hold the mouse button and draw a freehand path; release to complete (e.g., Brush, Highlighter).

Points are continuously appended while the button is held.

MultiPoint

Click to add points one at a time; double-click or press Enter to finish (e.g., Polyline, XABCDPattern, ElliottImpulse).

The number of required points varies by tool (see DrawingToolType::required_points()). Some tools (like Polyline) have no fixed limit.

NotDrawing

Not a drawing tool – cursor/interaction modes only (e.g., CrossCursor, Eraser).

These tools modify the cursor or provide utility functions but do not create Drawing objects.
