Usage

import React, { Component } from 'react';
import Designer from 'wfd';

const data = {
    nodes: [{ id: 'startNode', x: 50, y: 200, label: 'Start', clazz: 'start' },
      { id: 'taskNode1', x: 200, y: 200, label: 'Supervisor', assigneType: 'person', assigneValue: 'admin', isSequential:false, clazz: 'userTask' },
      { id: 'taskNode2', x: 400, y: 200, label: 'Manager', assigneType: 'person', assigneValue: 'admin', isSequential:false, clazz: 'userTask' },
      { id: 'decisionNode', x: 400, y: 320, label: 'Cost > 1000', clazz: 'gateway' },
      { id: 'taskNode3', x: 400, y: 450, label: 'CEO', clazz: 'userTask' },
      { id: 'endNode', x: 600, y: 320, label: 'End', clazz: 'end' }],
    edges: [{ source: 'startNode', target: 'taskNode1', sourceAnchor:1, targetAnchor:3, clazz: 'flow' },
      { source: 'taskNode1', target: 'endNode', sourceAnchor:0, targetAnchor:0, clazz: 'flow' },
      { source: 'taskNode1', target: 'taskNode2', sourceAnchor:1, targetAnchor:3, clazz: 'flow' },
      { source: 'taskNode2', target: 'decisionNode', sourceAnchor:1, targetAnchor:0, clazz: 'flow' },
      { source: 'taskNode2', target: 'taskNode1', sourceAnchor:2, targetAnchor:2, clazz: 'flow' },
      { source: 'decisionNode', target: 'taskNode3', sourceAnchor:2, targetAnchor:0, clazz: 'flow' },
      { source: 'decisionNode', target: 'endNode', sourceAnchor:1, targetAnchor:2, clazz: 'flow'},
      { source: 'taskNode3', target: 'endNode', sourceAnchor:1, targetAnchor:1, clazz: 'flow' },
      { source: 'taskNode3', target: 'taskNode1', sourceAnchor:3, targetAnchor:2, clazz: 'flow'},

class WFDemo extends Component {
    constructor(props) {
        super(props);
        this.wfDef = React.createRef();
    }
    
    handleSave = () => {
        const bpm = this.wfDef.current.graph.save();
    }
      
    render(){
        const candidateUsers = [{id:'1',name:'Tom'},{id:'2',name:'Steven'},{id:'3',name:'Andy'}];
        const candidateGroups = [{id:'1',name:'Manager'},{id:'2',name:'Security'},{id:'3',name:'OA'}];
        return (
            <>
                <a onClick={this.handleSave}>Save</a>
                <Designer data={data} ref={this.wfDef} height={600} mode={"edit"} lang="zh" users={candidateUsers} groups={candidateGroups}/>
            </>
        )
    }

Designer

属性

• data: 初始化数据
• height: 画布高度
• mode: view为只读，edit为可编辑
• lang: zh为中文，en为英文
• isView: 是否为预览模式（隐藏工具栏和属性栏）
• users: 选择审批人时对应的数据，数组内对象以id为键，name为值
• groups: 选择审批组时对应的数据，数组内对象以id为键，name为值

方法

• save(): 调用graph.save()生成json
• saveXML(): 调用graph.saveXML(createFile)生成Flowable XML，createFile参数是否同时生成xml文件，默认为true

Node
