在TypeScript中创建电子菜单?

我刚用TypeScript启动了一个简单的电子应用程序,我正在尝试设置我的自定义菜单。
menu = Menu.buildFromTemplate(template);无法编译,出现错误:
main.ts(109,35): error TS2345: Argument of type '({ label: string; submenu: ({ role: string; } | { type: string; })[]; } | { role: string; submenu...' is not assignable to parameter of type 'MenuItemConstructorOptions[]'.
我一定是遗漏了什么。在任何地方都找不到类型“MenuItemConstructorOptions”(但我可能找错了地方)。我的main.ts完整代码:

import { app, BrowserWindow, screen, Menu } from 'electron';
import * as path from 'path';

let win, menu;

function createWindow() {
    const electronScreen = screen;
    const size = electronScreen.getPrimaryDisplay().workAreaSize;

    win = new BrowserWindow({
        x: 0,
        y: 0,
        width: size.width,
        height: size.height
    });

    // and load the index.html of the app.
    win.loadURL('file://' + __dirname + '/index.html');
    win.webContents.openDevTools();
    win.on('closed', () => {
        win = null;
    });
}

function createMenu() {
    const template = [{
            label: 'Edit',
            submenu: [
                { role: 'undo' },
                { role: 'redo' },
                { type: 'separator' },
                { role: 'cut' },
                { role: 'copy' },
                { role: 'paste' },
                { role: 'pasteandmatchstyle' },
                { role: 'delete' },
                { role: 'selectall' }
            ]
        },
        {
            label: 'View',
            submenu: [
                { role: 'reload' },
                { role: 'forcereload' },
                { role: 'toggledevtools' },
                { type: 'separator' },
                { role: 'resetzoom' },
                { role: 'zoomin' },
                { role: 'zoomout' },
                { type: 'separator' },
                { role: 'togglefullscreen' }
            ]
        },
        { role: 'window', submenu: [{ role: 'minimize' }, { role: 'close' }] },
        {
            role: 'help',
            submenu: [{
                label: 'Learn More',
                click() {                           require('electron').shell.openExternal('https://electron.atom.io');
                }
            }]
        }
    ];
    menu = Menu.buildFromTemplate(template);
    Menu.setApplicationMenu(menu);
}

try {
    app.on('ready', function() {
        createWindow();
        createMenu();
    });
    app.on('window-all-closed', () => {
        if (process.platform !== 'darwin') {
            app.quit();
        }
    });

    app.on('activate', () => {
        if (win === null) {
            createWindow();
        }
    });
} catch (e) {
    throw e;
}

对我来说,将模板常量的类型设置为Electron.MenuItemConstructorOptions[]就足够了。
例如:

const template: Electron.MenuItemConstructorOptions[] = [{
        label: 'Edit',
        submenu: [
            { role: 'undo' },
            { role: 'redo' },
            { type: 'separator' },
            { role: 'cut' },
            { role: 'copy' },
            { role: 'paste' },
            { role: 'pasteandmatchstyle' },
            { role: 'delete' },
            { role: 'selectall' }
        ]
    },
    {
        label: 'View',
        submenu: [
            { role: 'reload' },
            { role: 'forcereload' },
            { role: 'toggledevtools' },
            { type: 'separator' },
            { role: 'resetzoom' },
            { role: 'zoomin' },
            { role: 'zoomout' },
            { type: 'separator' },
            { role: 'togglefullscreen' }
        ]
    },
    { role: 'window', submenu: [{ role: 'minimize' }, { role: 'close' }] },
    {
        role: 'help',
        submenu: [{
            label: 'Learn More',
            click() {
                require('electron').shell.openExternal('https://electron.atom.io');
            }
        }]
    }
];

对我来说,问题在于角色的适当资本化:

{ role: 'forceReload' },
  { role: 'toggleDevTools' }

超过

{ role: 'forcereload' },
  { role: 'toggledevtools' }

我无法在TS的JS中获得工作的示例。MenuItemConstructorOptions是在电子包的electron.d.ts文件中定义的一个接口。然而,我找到了一个解决方案,通过单独定义菜单项并将它们推到一个空数组中。有趣的是,里面的子菜单项被接受并工作,没有任何问题。这是工作的代码:

function createMenu() {
     const template = [];
     // Edit Menu
     template.push({
        label: 'Edit',
        submenu: [
           { role: 'undo' },
           { role: 'redo' },
           { type: 'separator' },
           { role: 'cut' },
           { role: 'copy' },
           { role: 'paste' },
           { role: 'pasteandmatchstyle' },
           { role: 'delete' },
           { role: 'selectall' }
        ]
     });
     // View Menu
     template.push({
        label: 'View',
        submenu: [
           { role: 'reload' },
           { role: 'forcereload' },
           { role: 'toggledevtools' },
           { type: 'separator' },
           { role: 'resetzoom' },
           { role: 'zoomin' },
           { role: 'zoomout' },
           { type: 'separator' },
           { role: 'togglefullscreen' }
        ]
     });
     // Windown menu
     template.push({
        role: 'window',
        submenu: [{ role: 'minimize' }, { role: 'close' }]
     });
     // Help menu
     template.push({
        role: 'help',
        submenu: [
           {
              label: 'Learn More',
              click() {
                 require('electron').shell.openExternal('https://electron.atom.io');
              }
           }
        ]
     });

     if (process.platform === 'darwin') {
        template.unshift({
           label: app.getName(),
           submenu: [
              { role: 'about' },
              { type: 'separator' },
              { role: 'services', submenu: [] },
              { type: 'separator' },
              { role: 'hide' },
              { role: 'hideothers' },
              { role: 'unhide' },
              { type: 'separator' },
              { role: 'quit' }
           ]
        });

        // Edit menu
        template[1].submenu.push(
           { type: 'separator' },
           { label: 'Speech', submenu: [{ role: 'startspeaking' }, { role: 'stopspeaking' }] }
        );

        // Window menu
        template[3].submenu = [{ role: 'close' }, { role: 'minimize' }, { role: 'zoom' }, { type: 'separator' }, { role: 'front' }];
     }

     menu = Menu.buildFromTemplate(template);
     Menu.setApplicationMenu(menu);
  }

希望这对任何人在同样的问题上绊倒有帮助

当我基于Electron的Menu示例编写菜单语法时,我也遇到了同样的错误,它在JavaScript中运行良好,但会扰乱TypeScript。不幸的是,MenuItemConstructorOptions[]template转换为suggested by PhoneixS对我不起作用。
在Electron的例子中,TypeScript似乎在三元菜单上绊倒了,它无法计算出它们的结果类型。在我的例子中,在封闭三元菜单的右括号后面添加as MenuItemConstructorOptions[],使TypeScript意识到它们毕竟是有效的子菜单。
有效TypeScript中的完整Electron示例:

import { app, Menu, MenuItemConstructorOptions, shell } from "electron"

const isMac = process.platform === 'darwin'

const menu = Menu.buildFromTemplate(
  [
    // { role: 'appMenu' }
    ...(isMac ? [{
      label: app.name,
      submenu: [
        { role: 'about' },
        { type: 'separator' },
        { role: 'services' },
        { type: 'separator' },
        { role: 'hide' },
        { role: 'hideothers' },
        { role: 'unhide' },
        { type: 'separator' },
        { role: 'quit' }
      ]
    }] : []) as MenuItemConstructorOptions[],
    // { role: 'fileMenu' }
    {
      label: 'File',
      submenu: [
        isMac ? { role: 'close' } : { role: 'quit' }
      ] as MenuItemConstructorOptions[]
    },
    // { role: 'editMenu' }
    {
      label: 'Edit',
      submenu: [
        { role: 'undo' },
        { role: 'redo' },
        { type: 'separator' },
        { role: 'cut' },
        { role: 'copy' },
        { role: 'paste' },
        ...(isMac ? [
          { role: 'pasteAndMatchStyle' },
          { role: 'delete' },

Menu.setApplicationMenu(menu)

在MenuItemConstructorOptions接口中,submenu属性是使用联合类型定义的。因此,需要将该属性强制转换为MenuItemConstructorOptions数组,以便识别推送运算符:

(windowMenu.submenu as MenuItemConstructorOptions[]).push(
  {
    type: 'separator',
  },
  {
    label: 'Bring All To Front',
    role: 'front'
  }
);

您有一个错误/错字我猜在这里:

{ type: 'separator' },

TypeScript无法解析类型,因为type属性未知(根据您的其他输入,应该是role
