Ellipse Tool

Import the Action

Start by importing the action:

import { WeaveEllipseToolAction } from "@inditextech/weave-sdk";

Register the Action

Then register the action on the Weave class instance.

const instance = new Weave({
  ...
  actions: [
    ...,
    new WeaveEllipseToolAction(), 
  ]
})

Setup the action trigger

Setup on a button or any element on the UI the user can interact with on the action event:

instance.triggerAction("ellipseTool");

For example on a button on React:

import React from "react";
import { useWeave } from "@inditextech/weave-react";

const MyEllipseToolTriggerComponent = () => {
  const instance = useWeave((state) => state.instance);

  const triggerTool = React.useCallback(() => {
    instance.triggerAction("ellipseTool");
  }, [instance]);

  return <button onClick={triggerTool}>Ellipse Tool</button>;
};

Trigger the action

Finally a final user trigger the UI element that launches the action.

When active the user can:

• Click on the canvas, it will create a ellipse with a default size.
• Touch on the canvas, it will create a ellipse with a default size.
• Click & drag to create a ellipse and define its radius on both axis (X axis control the x-radius and y axis controls the y-radius, if both radius are the same you have a circle).

Once clicked or click-drag finishes, the ellipse is added to the canvas as a fully functional node—ready. This action integrates seamlessly with Weave.js's real-time state system, ensuring the new element appears instantly for all connected users.
