electron实现类似QQ来新消息时的闪烁与任务栏窗口提醒

const path = require('path');
const electron = require('electron');
const {
    app,
    BrowserWindow,
    Menu,
    ipcMain,
    Tray
} = electron;

let mainWnd = null;

mainWnd = new BrowserWindow({
    minWidth: 1200,
    minHeight: 750,
    resizable: true,
    icon: 'icon.ico',
    skipTaskbar: false
});

let appIcon = new Tray(iconPath);

const contextMenu = Menu.buildFromTemplate([{
    label: '移除',
    click: function() {
        event.sender.send('tray-removed');
    }
}, {
    type: 'separator'
}, {
    label: 'Item1',
    type: 'radio'
}, {
    type: 'separator'
},{
    label: 'MenuItem2',
    type: 'checkbox',
    checked: true
}]);

// Make a change to the context menu
contextMenu.items[2].checked = false;

appIcon.setToolTip('在托盘中的 Electron 示例.');

appIcon.setContextMenu(contextMenu);


var count = 0;
setInterval(function() {
    if (count++ % 2 == 0) {
        appIcon.setImage(path.join(__dirname, '../img/tray/tray_icon_2.png'));
    } else {
        appIcon.setImage(path.join(__dirname, '../img/tray/tray_icon.png'));
    }
}, 400);
