[嵌入式Linux项目实战开发]基于QT4.8的仓库管理系统实现功能【2019年给力项目】

支持导出 excel 表格
支持查看商品操作日志
支持高精度浮点运算
支持同一商品以不同价格入库
该软件已开源。
因预览版可执行文件过大，所以上传到csdn
大家有问题，可以加我的QQ1653687969

源码目录结构：

部分代码：

现在跟大家介绍一下软件实现界面:
初始化数据库

主界面

#include "main_menu.h"MainMenu::MainMenu(QWidget *widget): QMenu(widget)
{this->createActions();this->translateActions();
}void MainMenu::createActions()
{//创建菜单项action_sqlinit = new QAction(this);action_changepasswd = new QAction(this);action_sqlinit->setIcon(QIcon("img/safe.png"));//添加菜单项this->addAction(action_sqlinit);this->addAction(action_changepasswd);//设置信号连接QObject::connect(action_sqlinit, SIGNAL(triggered()), this, SIGNAL(sqlinit_signal()));QObject::connect(action_changepasswd, SIGNAL(triggered()), this, SIGNAL(changepasswd_signal()));
}void MainMenu::translateActions()
{action_sqlinit->setText(tr("初始化数据库"));action_changepasswd->setText(tr("修改管理员密码"));
}

入库

出库

搜索商品
