GridLayout init model error: nodeSize is not a function or its return value is not iterable

[vran]

问题描述

在使用 ANTV X6 集成 Layout ，使用 GridLayout 初始化模型数据时会出现异常：nodeSize is not a function or its return value is not iterable，尝试 Copy 官方源码实验也会出现同样的异常。

尝试使用 Dagre、Circle 的布局模式没有出现异常

版本依赖

• @antv/x6@1.30.1
• @antv/layout@0.2.1

场景复现

尝试将自定义的 er-rect 换成标准的 rect 依然报错

const graph = new Graph({
    container: document.getElementById('diagram-container'),
    grid: true,
    panning: true,
    snapline: true,
    selecting: {
        enabled: true,
        showNodeSelectionBox: true,
    },
    connecting: {
        snap: true,
        createEdge() {
            return graph.createEdge({
                shape: 'er-edge',
                strokeDasharray: 5,
                zIndex: 1
            })
        }
    },
})

const model = {
    nodes: [
        {
            "id":"departments",
            "shape":"er-rect",
            "size":{
                "width":224,
                "height":40
            },
            "width":224,
            "height":40,
            "label":"departments"
        }
    ],
    edges: []
}
const gridLayout = new GridLayout({
    type: 'grid',
})
const newModel = gridLayout.layout(model)   // throw error: nodeSize is not a function or its return value is not iterable
console.log(newModel)
graph.fromJSON(newModel)

if (preventOverlap || paramNodeSpacing) {
    const nodeSpacing = getFuncByUnknownType(10, paramNodeSpacing);
    const nodeSize = getFuncByUnknownType(30, paramNodeSize, false);
    layoutNodes.forEach((node) => {

我也遇到了同样的问题，nodeSize(node) 返回的是数字，扩展赋值会报错。

看了报错的源码，貌似可以在这写个方法 ，但是port的线条还是绞着的 @Leridy @wflixu
const gridLayout = new GridLayout({
type: "grid",
width: 600,
height: 400,
center: [300, 200],
rows: 4,
cols: 4,
//自定义函数
nodeSize(node) {
console.log("--node--", node);
return [var_node_width, var_nodeHead_height + node.ports.length * var_nodePort_height];
},
});

@499190982 我通过在实例化 GridLayout 的时候传入了 nodeSize 规避了这个报错

  const gridLayout = new GridLayout({
    type: "grid",
    width: 1000,
    height: 1000,
    cols: 4,
    rows: 4,
    nodeSize: [100, 100],
  });

至于port 线条绞着，我没有留意
