For handling the actions you can use the Event Bus methods

Example​

Use the api.exec() method to trigger the action:

import { useRef } from "react";
import { getData } from "./common/data";
import { Gantt } from "@svar-ui/react-gantt";
import { Button } from "@svar-ui/react-core";

export default function Example() {
  const data = getData();
  const apiRef = useRef(null);

  function handleMove(mode) {
    const api = apiRef.current;
    if (!api) return;
    const selected = api.getState().selected;
    api.exec("move-task", { id: selected, mode });
  }

  return (
    <>
      <Button
        type="primary"
        onClick={() => {
          handleMove("up");
        }}
      >
        Move task up
      </Button>

      <Gantt tasks={data.tasks} ref={apiRef} />
    </>
  );
}
