example

import { register } from "x6-html-shape";

register({
  shape: "html-shape-for-react",
  render: (node, graph, container) => {
    const root = createRoot(container);
    root.render(<CustomComponent node={node} />);
    return () => root.unmount();
  },
  width: 100,
  height: 40
});


const graph = new Graph({
  container: this.container,
  background: {
    color: "#F2F7FA"
  }
});

graph.addNode({
  shape: "html-shape-for-react",
  x: 100,
  y: 200,
  label: 'rect', 
})

事件穿透

1. 由于DOM层级关系，html-shape实现的节点总是在svg上层
2. 通过给x6-html-shape-container设置pointer-events: none屏蔽这一层的交互，使得鼠标事件能穿透到svg内部节点。但是x6-html-shape-node内部有一些元素是需要交互的，所以给节点打开
3. 至于事件穿透使用forwardEvent将节点内部的鼠标事件转发到对应的x6-node内部

export function forwardEvent(eventType, fromElement, toElement) {
  fromElement.addEventListener(eventType, function (event) {
    toElement.dispatchEvent(new event.constructor(event.type, event));
    event.preventDefault();
    event.stopPropagation();
  });
}
