使用 electron 实现类似新版 QQ 的登录界面效果(阴影、背景动画、窗体3D翻转)


Posted in Javascript onOctober 23, 2018

现在什么都讲究追赶潮流,觉得 QQ 登录窗口做的效果不错,既然刚学习 electron ,那么就用 electron 模仿一下。其实主要用到的就是 CSS3 的效果:边框圆角、阴影,3D变换。对,就这么简单。先上效果:

使用 electron 实现类似新版 QQ 的登录界面效果(阴影、背景动画、窗体3D翻转)

下面是关键代码:

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.
