Qt实现小型的超市收银系统
作为联系，打算用Qt开发一个小型的收银系统，从开始的构思，到基本功能的实现，经历了些时间，很多时候是学校的其他事情打扰的不行，没能静下心来连续做，那样的话就会快很多了。 其实真正做一件东西的时候，需要我们静下心来不断的去做，这样心里感觉会好很
作为联系，打算用Qt开发一个小型的收银系统，从开始的构思，到基本功能的实现，经历了些时间，很多时候是学校的其他事情打扰的不行，没能静下心来连续做，那样的话就会快很多了。
其实真正做一件东西的时候，需要我们静下心来不断的去做，这样心里感觉会好很多。今天记录下自己做这个项 目的过程，以后翻出来还可以看看。
本人很喜欢本着开源的心来学习的，但是好多的人都很吝啬，只能这样说了，可能不好听，但是现实就是这样，不过这开发这个项目的过程中让我欣慰的是，我以外的发现了一位大神，Qt大神，他将自己写的东西都开源出来，让我从中学到了很多的东西，在这里感谢他。
由于本人也是个菜鸟，在加上分少的可怜，所以就只能这样做了，如果没有积分下载的可以告我邮箱，我发给你。程序中不免有些BUG王大家指出。

提供源码像让大家互相学习。
1、先来一张登陆的界面：
界面比较粗糙。难看，本人表示只在上面贴了张图片而已，想要美观的可自行在深一步设计。登陆界面中可以选择登陆的名称和工号，这些都是从数据库中查找到的。
2、进入主界面（密码和名称正确的前提下）
哈哈，界面很丑吧。不过没有关系，咋要的是功能，界面丑陋与美那是后期的事。几个样式表统统解决问题。见后面的文章。
主要就是这些功能，有的没有实现，需要去慢慢的做。喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vc3Ryb25nPjwvcD4KPHA+PHN0cm9uZz4zoaLHsMyoz/rK273nw+Y8L3N0cm9uZz48L3A+CjxwPjxzdHJvbmc+PGltZyBzcmM9"http://www.2cto.com/uploadfile/Collfiles/20141112/2014111209210111.png" alt="\">
主要就那些东西，功能差不多是现代了可以参考下设计的思路，可能方法不是很好，实现的方法与很多，很想让大家指出最优的方法。
4、采购进货
5、会员管理界面
6退出
在退出的过程中，提醒用户是否备份数据，以防止用户不小心关掉系统，二数据库数据出现问题，造成不必要的损失。
功能还不够完善，需要改进的地方还很多。望大家指出，共同交流学习。。
在这之后我参照了对Qt方面比较牛逼的大神做的东西，借鉴了下，将我的系统改善了下，效果如下图所示：
liudianwu 开源的东西，对我的影响很大。多谢你……
技术在于交流……

The programming language PHP is a powerful tool for web development, capable of supporting a variety of different programming logics and algorithms. Among them, implementing the Fibonacci sequence is a common and classic programming problem. In this article, we will introduce how to use the PHP programming language to implement the Fibonacci sequence, and attach specific code examples. The Fibonacci sequence is a mathematical sequence defined as follows: the first and second elements of the sequence are 1, and starting from the third element, the value of each element is equal to the sum of the previous two elements. The first few elements of the sequence
Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent
Apr 07, 2024 am 09:10 AM
On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A
