name | type | default | description |
---|---|---|---|
data | object | { nodes: []; lines: [] } | 数据 |
snapline | bool | true | 是否显示辅助对齐线 |
lineLinkageHighlight | boolean | false | hover 节点线条是否联动高亮 |
lineColor | object | {} | 线条颜色映射对象 eg: {'锚点1': '#82BEFF', '锚点2': '#FFA39E'} |
lineTextColor | object | {} | 线条上文字颜色映射对象 eg: {'锚点1': '#82BEFF', '锚点2': '#FFA39E'} |
lineOffsetY | number | 0 | 线条起始点向上偏移量 |
startPointAnchorId | string | 保持所有线条起始点与 startPointAnchorId 线条一致 | |
anchorPlacement | string | 锚点位置,若值为 bottom,则位于锚点的父节点底部 | |
selectionAutoScroll | boolean | false | 是否开启框选至边缘时画布自动滚动 |
lineTextMap | object | {} | 线条上文字与 anchorId 映射对象 eg: {'anchorId1': '锚点1', 'anchorId2': '锚点2'} |
lineTextDecorator | (text: textPosition, line: ITopologyLine) | - | 线条上文字装饰器 |
showText | (start: string) => boolean | - | 当 anchorId 为 startPointAnchorId 时, 是否显示线条文字 |
showBar | bool | true | 是否显示工具栏 |
showCenter | bool | true | 是否显示工具栏中的定位中心 |
showLayout | bool | true | 是否显示工具栏中的自动布局 |
showDownload | bool | false | 是否显示工具栏中的下载图片 |
showMinimap | bool | false | 是否显示小地图 |
allowNodeInsertOnEdge | boolean | 是否开启拖拽节点到线中间进行节点插入 | |
canConnectMultiLines | bool | false | 控制一个锚点是否可以连接多条线 |
overlap | bool | false | 是否允许节点覆盖,默认允许,设置 true 时不允许 |
overlapCallback | () => void | overlap 为 true 时的回调 | |
overlapOffset | {} | {offsetX: 0, offsetY: 0} | overlap 为 true 时,节点的 x,y 偏移量 |
customPostionHeight | number | 0 | 未设置 customPostionHeight 画布默认居中展示,当设置 customPostionHeight 时,画布距离顶部 customPostionHeight |
readOnly | bool | false | 只读模式,为true时不可编辑 |
prevNodeStyle | object | - | 控制预览节点样式,目前支持配置 border、background 属性 |
isReduceRender | bool | false | 控制节点 shouldComponentUpdate 生命周期的返回值 |
autoLayout | bool | false | 自动布局,当数据中没有position属性时将自动计算布局。 |
renderTreeNode | (node,decorators) => ReactNode | - | 子节点render方法,接收节点数据,返回JSX。 |
getInstance | (instance: Topology) => void | - | 返回组件实例,用于调用组件内部的方法。 |
onChange | (data, changeType) => void | - | 数据发成改变时触发,changeType为改变的类型 |
onSelect | (data) => void | - | 选中数据时触发,返回当前选中的数据(包含节点、线段) |
sortChildren | (parent, children) => sortedChildren | - | 子节点排序回调,可选,默认无。 |
node options 中 一些可配置参数
name | type | default | description |
---|---|---|---|
id | string | - | 节点id |
canDrag | boolean | true | 控制节点是否可拖拽 |
dragChild | boolean | false | 设置当前节点下的子节点是否需要联动拖动 |
filterOverlap | boolean | false | 控制节点在设置 overlap 为 true 时是否仍允许被覆盖 |
返回topology组件的实例,可通过实例调用组件内部的方法:
移动到中心,当所有节点都有位置数据(positions)时,移动的中心点为内容的中心,否则为画布的中心。
自动计算布局
renderTreeNode的第二个参数,包含以下装饰器函数:
anchorDecorator是一个高阶函数,经过 anchorDecorator 包装的控件将变成一个锚点。
anchorDecorator(options)(ReactNode)
name | type | default | description |
---|---|---|---|
anchorId | string | - | 锚点唯一id,如果不传将默认生成一个自增的id |
模板装饰器,用于包装模板组件
disabled 字段控制 TemplateNode 是否启用
<TemplateWrapper disabled generator={this.generatorNodeData}>
<div>模板节点</div>
</TemplateWrapper>
name | type | default | description |
---|---|---|---|
data | () => nodeData | - | 数据生成器,用于产生节点数据 |
