javascript - 如何在 Electron 中注册多个全局快捷方式？

问题描述

我正在https://github.com/electron/electron-quick-start之上构建原型

我在main.js中有以下代码，在其他文件中没有其他代码：

const electron = require('electron')
// Module to control application life.
const app = electron.app
// Module to create native browser window.
const BrowserWindow = electron.BrowserWindow

const path = require('path')
const url = require('url')
const globalShortcut = electron.globalShortcut
const {clipboard} = require('electron')

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let mainWindow

function createWindow () {
  // Create the browser window.
  mainWindow = new BrowserWindow({width: 800, height: 600})

  // and load the index.html of the app.
  mainWindow.loadURL(url.format({
    pathname: path.join(__dirname, 'index.html'),
    protocol: 'file:',
    slashes: true
  }))

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()

  // Emitted when the window is closed.
  mainWindow.on('closed', function () {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null
    globalShortcut.unregisterAll();
  })
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', function() {
  createWindow();
  globalShortcut.register('Alt+h', () => {
    let date = new Date();
    clipboard.writeText(date.toLocaleString());
  });

  globalShortcut.register('Alt+c', function() {
    clipboard.writeText('Multitabler spin 2 tables');
  });
})

// Quit when all windows are closed.
app.on('window-all-closed', function () {
  // On OS X it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

app.on('activate', function () {
  // On OS X it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (mainWindow === null) {
    createWindow()
  }
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

在“就绪”事件中，我注册了两个快捷键：Alt+h 和 Alt+c。Alt+h 的工作原理是将日期复制到我的剪贴板，但另一个快捷方式不会向剪贴板产生任何输出。

我尝试了什么：我尝试用 console.log 语句替换第二个快捷方式中的剪贴板写入事件。当我按下那个组合键时没有输出。

无论应用程序是聚焦还是最小化，我如何注册多个激活的全局短代码。

解决方案

您的代码确实有效。我在我的 windows 和 mac 上测试过。可能是快捷键冲突，可能是Alt+c被其他软件占用了。

另外我建议你在windows focus而不是app ready上注册快捷键，因为Electron会阻塞其他使用相同快捷键的软件。

const refreshCommand = process.platform === 'darwin' ? 'Cmd+R' : 'F5'

app.on('browser-window-focus', () => {
globalShortcut.register(refreshCommand, () => {
    // do something
})
})

app.on('browser-window-blur', () => {
globalShortcut.unregisterAll()
})
