本文介绍如何使用Electron框架创建桌面应用，包括主进程和渲染进程的交互，窗口对象的创建、加载及显示控制，以及子窗口和模态窗口的实现方式。

  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    frame:false,   弹出的窗口有无边框,默认为有
    show:false,    是否显示窗口,否后,通过对象.show()打开
    backgroundColor:"#ADD6FF"   设置背景色,16进制rgba格式
    webPreferences: {  网页功能设置
      preload: path.join(__dirname, 'preload.js'),     脚本路径
      nodeIntegration:true,     配置
      webviewTag:true           配置
    },
  })
	
 让窗口加载内容
	窗口对象.loadFile('路径');
	窗口对象.loadURL('url');
	
 等到窗口内容加载完后再显示
 	1、设置show:false
 	2、设置监听
	 	窗口对象.once("ready-to-show",()=>{窗口对象.show();})

 子窗口
 	不指定坐标和大小,默认和父窗口一样大且覆盖在上面
 	父窗口关闭,子窗口也关闭
 	
	 	var 子窗口对象=new BrowserWindow({
	 		x:弹出窗口x坐标
	 		y:弹出窗口y坐标
			parent:父窗口对象
		})
		子窗口对象.show()

模态子窗口
	弹出改窗口后,不能点击父窗口
	在子窗口的基础上,在创建时添加属性modal:true

文档
渲染进程加载页面
在这里插入图片描述

代码示例:

// Modules to control application life and create native browser window
const {app, BrowserWindow} = require('electron')
const path = require('path')

function createWindow () {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    //弹出的窗口有无边框,默认为有
    // frame:false,
    show:false,
    backgroundColor:'#586148',
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
      nodeIntegration:true,
      webviewTag:true
    },
  })

  // and load the index.html of the app.
  mainWindow.loadFile('index.html')
  mainWindow.webContents.on("did-finish-load",()=>{
      
  })
  mainWindow.webContents.on('dom-ready',()=>{
   
  })
  mainWindow.once('ready-to-show',function(){
    mainWindow.show();
    child.show();
  })

  var child=new BrowserWindow({
    x:0,
    y:0,
    //父消失,子也消失
    parent:mainWindow,
    modal:true
  })


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

// 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.whenReady().then(createWindow)
app.on('ready',()=>{

  createWindow();

});

// Quit when all windows are closed.
app.on('window-all-closed', function () {
  // 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', function () {
  // 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 (BrowserWindow.getAllWindows().length === 0) 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.
