本文将介绍在代码和XML配置中的修改,支持表格的单选功能。 先自定义一个widget,继承平台默认的table @SPI.ClassFactory( BaseElementWidget.Token({ viewType: ViewType.Table, widget: 'MyRadioTable' }) ) export class MyRadioTable extends TableWidget { @Widget.Reactive() protected get selectMode(): ListSelectMode { return ListSelectMode.radio; } } 注册layout 如果当前是主表格,那么xml配置如下 const xml = `<view type="TABLE"> <pack widget="group"> <view type="SEARCH"> <element widget="search" slot="search" slotSupport="field" /> </view> </pack> <pack widget="group" slot="tableGroup"> <element widget="actionBar" slot="actionBar" slotSupport="action"> <xslot name="actions" slotSupport="action" /> </element> <element widget="MyRadioTable" slot="table" slotSupport="field"> <element widget="expandColumn" slot="expandRow" /> <element widget="RadioColumn" /> <xslot name="fields" slotSupport="field" /> <element widget="rowActions" slot="rowActions" slotSupport="action" /> </element> </pack> </view>` registerLayout(xml, { moduleName: '模块名称', model: '模型', viewType: ViewType.Table }) 如果当前的表格是form表单页面的表格,那么xml配置如下 const xml = `<view type="TABLE"> <view type="SEARCH"> <element widget="search" slot="search" slotSupport="field" /> </view> <element widget="actionBar" slot="actionBar" slotSupport="action"> <xslot name="actions" slotSupport="action" /> </element> <element widget="MyRadioTable" slot="table"> <element widget="expandColumn" slot="expandRow" /> <element widget="RadioColumn" /> <xslot name="fields" slotSupport="field" /> <element widget="rowActions" slot="rowActions" /> </element> </view>` registerLayout(xml, { moduleName: '模块名称', model: '模型', viewType: ViewType.Table })
