Usage

Import the Action

Start by importing the action:

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

Register the Action

Then register the action on the Weave class instance.

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

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("zoomInTool");

For example on a button on React:

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

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

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

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

Trigger the action

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

When triggered increases the zoom level of the canvas by one step.
