按“esc”时退出全屏(使用带电子的javascript)

我正在开发一个应用程序(带电子),我希望用户能够在按下“esc”时退出全屏模式.我尝试了不同的方法,徒劳无功.
以下是以全屏模式在新浏览器窗口中启动应用程序以及显示和 HTML / CSS内容的代码：

'use strict';

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

// 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({fullscreen:true});

  // and load the index.html of the app.
  mainWindow.loadURL('file://' + __dirname + '/index.html');

  // 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;
  });
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
app.on('ready',createWindow);

// 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();
  }
});

这是我正在尝试添加到此代码,以便能够退出全屏但它不起作用：

app.on('keydown',function(e){
    if(e.keyCode === 27){
      app.exitFullscreen();
    }
});

我也试过“cancelFullscreen”.而“全屏：假”.不工作.

非常感谢您的关注！

解决方法

这很容易.在渲染过程中添加键盘侦听器,然后通过远程模块操作窗口.

const remote = require("electron").remote;

    document.addEventListener("keydown",event => {

        switch (event.key) {
            case "Escape":
                if (remote.getCurrentwindow().isFullScreen()) {
                    remote.getCurrentwindow().setFullScreen(false);
                }
                break;
             }
    });
