设置窗口图标，在窗口初始时加入icon参数即可

  win = new BrowserWindow({
    icon: './src/img/icon.png',
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true
    }
  })

系统托盘图标与菜单

  const { app, BrowserWindow, Menu, shell, ipcMain, Tray } = require('electron')
  
  //创建任务栏图标、菜单
  const tray = new Tray('./src/img/icon.png');
  const trayContextMenu = Menu.buildFromTemplate([
    {
      label: '打开',
      click: () => {
        win.show();
      }
    }, {
      label: '退出',
      click: () => {
        app.quit();
      }
    }
  ]);
  
  tray.setToolTip('myApp');
  tray.on('click', () => {
    win.show();
  });
  tray.on('right-click', () => {
    tray.popUpContextMenu(trayContextMenu);
  });
