使用 electron 實現類似新版 QQ 的登錄界面效果(陰影、背景動畫、窗體3D翻轉)

使用 electron 實現類似新版 QQ 的登錄界面效果(陰影、背景動畫、窗體3D翻轉):現在什么都講究追趕潮流，覺得 QQ 登錄窗口做的效果不錯，既然剛學習 electron ，那么就用 electron 模仿一下。其實主要用到的就是 CSS3 的效果：邊框圓角、陰影，3D變換。對，就這么簡單。先上效果：下面是關鍵代碼： app.js 'use st

現在什么都講究追趕潮流，覺得 QQ 登錄窗口做的效果不錯，既然剛學習 electron ，那么就用 electron 模仿一下。其實主要用到的就是 CSS3 的效果：邊框圓角、陰影，3D變換。對，就這么簡單。先上效果：

下面是關鍵代碼：

app.js

'use strict';
const { app, BrowserWindow } = require('electron')
const path = require('path')
const url = require('url')
// 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 win
function createWindow() {
 // Create the browser window.
 win = new BrowserWindow({
 width: 495, height: 470, /*skipTaskbar: true,*/ frame: false,
 resizable: false, transparent: true, show: false, alwaysOnTop: true
 })
 win.once('ready-to-show', () => {
 win.show()
 })
 // and load the index.html of the app.
 win.loadURL(url.format({
 pathname: path.join(__dirname, '/app/index.html'),
 protocol: 'file:',
 slashes: true
 }))
 // Open the DevTools.
 //win.webContents.openDevTools()
 // Emitted when the window is closed.
 win.on('closed', () => {
 // 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.
 win = null
 })
}
//app.disableHardwareAcceleration();
// 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', createWindow)
// Quit when all windows are closed.
app.on('window-all-closed', () => {
 // On macOS 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', () => {
 // On macOS 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 (win === 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.
