3.5.7.8 自定义菜单栏

在业务中，可能会遇到需要对菜单栏的交互或UI做全新设计的需求，这个时候可以自定义菜单栏组件支持。

首先继承平台的CustomMenuWidget 组件，将自己vue文件设置到component处

import { NavMenu, SPI, ViewWidget } from '@kunlun/dependencies';
import Component from './CustomMenu.vue';

@SPI.ClassFactory(
  ViewWidget.Token({
    // 这里的widget跟平台的组件一样，这样才能覆盖平台的组件
    widget: 'nav-menu'
  })
)
export class CustomMenuWidget extends NavMenu {

  public initialize(props) {
    super.initialize(props);
    this.setComponent(Component);
    return this;
  }
}

vue文件中继承平台的props，编写自定义页面代码

export const NavMenuProps = {
  /**
   * 当前模块
   */
  module: {
    type: Object as PropType<IModule | null>
  },
  /**
   * 树结构的菜单
   */
  menus: {
    type: Array as PropType<IResolvedMenu[]>,
    default: () => []
  },
  /**
   * 菜单类型，现在支持垂直、水平、和内嵌模式三种
   */
  mode: {
    type: String as PropType<'vertical' | 'horizontal' | 'inline'>,
    default: 'inline'
  },
  /**
   * 菜单栏是否折叠收起
   */
  collapsed: {
    type: Boolean,
    default: false
  },
  /**
   * 当前展开的 SubMenu 菜单项 key 数组
   */
  openKeys: {
    type: Array as PropType<string[]>,
    default: () => []
  },
  /**
   * 当前选中的菜单项 key 数组
   */
  selectKeys: {
    type: Array as PropType<string[]>,
    default: () => []
  },
  /**
   * 菜单搜索下拉选中菜单项
   */
  selectMenuBySearch: {
    type: Function as PropType<(menuName: String) => void>
  },
  /**
   * 选中菜单项
   */
  selectMenu: {
    type: Function as PropType<(menuName: String) => Promise<void>>
  },
  /**
   * SubMenu 展开/关闭的回调
   */
  openChange: {
    type: Function as PropType<(openKeys: string[]) => void>
  },
  /**
   * 菜单栏折叠的回调
   */
  onChangeCollapsed: {
    type: Function as PropType<(collapsed: boolean) => Promise<void>>
  }
};

文件目录结构如下图

最后再到运行路径中导入该组件

这里以启动工程的 main.ts 举例，如果运行时未看到该组件的效果，请检查是否正确导入到运行时的路径中

以上自定义菜单栏的页面效果如下（该组件仅供演示，所以未实现3级菜单，可自行用子组件实现）
