Qt实战：云曦日历篇

前言

自国务院印发《推进普惠金融发展规划（2016—2020年）》通知以来，各省、自治区、直辖市人民政府、国务院各部委各直属机构积极响应，认真贯彻执行，普惠金融发展已经进入了高潮阶段，各大互联网公司和高校紧跟时代潮流，推出了各种创新性产品和软件，该软件作为一款以培养兴趣，提高学生软件项目的编程项目能力为目的，所创建的一款实用性的软件，以日历为依托，创建了许多相关的特效，优美界面和天气查询、日程管理等实用性功能，且界面等均符合当下青少年的审美需求，是一款紧跟潮流的日历软件

一、云曦日历效果图

1. 返回今天：

如图1，当点击左右查询日期时，点击返回今天后，会自动回到当前日期，并将底色变为蓝色。

2. 天气查询：

如图2，点击查询按钮后，可输入所要查询的城市，点击获取天气按钮后，即可显示所要查询的城市的天气情况

3. 天气刷新：

该功能主要用于刷新主界面由于网络问题，而无法及时显示天气的情况，如图3，点击刷新后，即可解决该问题。

4. 日程管理：

双击所要建立日程的时间，会弹出一个日程编辑框，如图4所示，输入所要建立的日程后，点击主界面的加号按钮，即可将当前日程显示出来，当然，要删除的话，点击减号即可。具体操作流程如下：
