前篇：vue3+antv x6自定义节点样式
1、创建侧边栏
- 用antd的menu来做侧边栏
npm i --save ant-design-vue@4.x
//入口文件main.js内
import Antd from 'ant-design-vue';
import App from './App';
import 'ant-design-vue/dist/reset.css';const app = createApp(App);
app.use(Antd).mount('#app');
- 侧边栏结构
// index.js内，拖拽节点侧边栏
export const MENU_TREE = [{key: '1',label: 'type1',title: 'drag node 1',},
]
- 画布展示
//index.vue内
<template><div class="box"><a-menuclass="menutree":items="menutree"/><div id="container"></div></div><TeleportContainer/>
</template>
<script setup lang='ts'>
import {MENU_TREE} from "./index";
let menutree = MENU_TREE
</script>
<style scoped>
.menutree{display: flex;position: relative;
}
#container{height: 100vh;
}
.menutree{width: 200px;height: 100vh;position: absolute;left: 0;top: 0;flex-direction: column;z-index: 2;user-select: none;/* 鼠标按下时没有复制等操作 */
}
</style>
2、拖拽交互
- 安装
npm install @antv/x6-plugin-dnd --save
- 引入并使用（index.vue）
import { Dnd } from '@antv/x6-plugin-dnd'
//...
let dnd:Dnd
//开始拖拽
const startDrag = (e,nodevo)=>{const node = graph.createNode(formatData(nodevo))dnd.start(node, e)
}
//初始化画布
const graphInit = ()=>{//...dnd = new Dnd({target: graph,getDragNode: (node) => node.clone({ keepId: true }),//拖拽开始时，获取被拖拽的节点，默认克隆 dnd.start 传入的节点。getDropNode: (node) => {//拖拽结束时，获取放置到目标画布的节点，默认克隆被拖拽的节点。return graph.createNode(formatData(node.getData()))}})
}
3、侧边栏和拖拽建立联系
- 在侧边栏menu中添加拖拽节点信息（index.js）
MENU_TREE = [{key: '1',label: 'type1',title: 'drag node 1',ports:[{id: 'port-1',name: 'drag1-port1',}]
}]
- fomatMenu处理menu内需要拖拽到节点信息（index.js）
export function fomatMenu (menu: any, dragStart) {let tempmenu = menu.map(ele => {const nodeVO = {id: `node-${Math.random()}`,nodeName: ele.title,x: 0,y: 0,ports: ele.ports}return {key: ele.key,label: ele.label,onMousedown: (e: Event) => {dragStart(e, nodeVO)},}});return tempmenu
}
- 主画布渲染menu时先处理menu信息
import {MENU_TREE,fomatMenu} from "./index";
let menutree = fomatMenu(MENU_TREE,startDrag) //放在startDrag之后
- 效果
