定义组件样式 - 使用静态属性

name

name: string

items

items: any[]

iconFilePath

iconFilePath: string

clear

clear: () => void

_menuId

_menuId: string

菜单 ID，设置后自动启用动态菜单项合并。对应 MenuRegistry 中的菜单 ID（如 'file', 'create', 'edit' 等）。

_baseItems

_baseItems: MenuItem[]

基础菜单项数组。子类在构造函数中 push 到此数组（而非 this.items）， show() 时会自动合并动态项后赋值给 this.items。外部可通过 MenuBar.applyCustomConfig 直接操作此数组进行定制。

renderRoot

renderRoot: any

Accessors

`Static`observedAttributes

get observedAttributes(): any[]
Returns any[]
Inherited from MenuPanel.observedAttributes
- Defined in vendor/lit-element-base.ts:103

updateComplete

Returns any
Inherited from MenuPanel.updateComplete
- Defined in vendor/lit-element-base.ts:306

Methods

`Static`registerDynamicItemsProvider

registerDynamicItemsProvider(
provider: (menuId: string) => DynamicMenuItemEntry[],
): void
注册动态菜单项 provider（由 MenuBar 调用一次）
Parameters
- provider: (menuId: string) => DynamicMenuItemEntry[]
Returns void

- Defined in ui/MenuPanel.ts:34

setPosition

setPosition(t: any): void
设置位置
Parameters

Returns void
Inherited from MenuPanel.setPosition
