Example​

In the example below we apply the api.exec method to trigger the action with a button click:

import { getData } from "./common/data";
import { Gantt } from "wx-react-gantt";
import { Button } from "wx-react-wx";
import { useRef } from "react";

const App = () => {
  const data = getData();
  const apiRef = useRef();

  const updateLink = () => {
    apiRef.current.exec("update-link", {
      id: 1,
      link: { type: 3 },
    });
  };

  return (
    <>
      <Button onClick={updateLink} type="primary">Update Link</Button>
      <Gantt
        ref={apiRef}
        tasks={data.tasks}
        links={data.links}
        // other settings
      />
    </>
  );
};

export default App;
