QT5实现职工工资信息管理系统（文件读写）

暑期学校QT实践项目

题目要求

该系统需创建和管理如下信息：1、职工信息：工号、姓名、年龄、入职日期、电话、住址、月工资数据集。2、月工资信息：月份、基本工资、岗位工资、工龄工资、津贴、岗贴、补贴、房贴、交通补贴。
系统功能要求如下：
1．创建和管理职工信息的对象；
2．创建和管理月工资信息的对象；
3．增加和删除职工；
4．针对特定职工增加和删除月工资信息；
5．基本查询功能；
6．数据文件读写：文件中包含所有职工信息、每个职工的月工资信息等数据；
7．基本信息显示：1）所有职工的信息显示；2）特定职工的月工资信息；
8．可选功能提升：在显示中增加个人所得税（个人所得税计算方法设为：工资少于800元为0；800～1000元的部分为5％；1000～5000元的部分为10％；5000元以上的部分为20％）、实发数等显示。

成品展示

主界面

选择读取文件

添加职工

查看特定职工薪资

添加特定职工薪资信息

删除职工

删除特定薪资信息

帮助界面

查询职工信息

查询薪资信息

查看特定薪资税后收入

修改信息（在工具栏编辑中选择修改后方可修改）

薪资情况简单统计

一些说明

还存在一些bug , 包括
1.添加职工信息和薪资信息时不能判断是否出现编号重复的错误。
2.薪资统计功能必须所有职工的工资信息存在且不为0，否则会出现"nan"……
3.薪资统计功能有待完善
……
（希望各位dalao批评指正）

首先是4个类，薪资类，薪资表类，职工类，职工表类来存储基本信息。

    readonlydelegate* readOnlyDelegate = new readonlydelegate(this);

}

4.查询视图显示（在职工信息视图下查询职工，薪资信息视图下查询薪资）

void MainWindow::show_SelectTable()

            employeeTableView->setItem(i,6,aTempItem);
        }
        ui->label_num->setText(QString("职工人数：%1人").arg(indexlist.size()));

         employeeTableView->setHorizontalHeaderLabels(templist);

         int RowCnt=indexlist1.size();
         employeeTableView->setRowCount(RowCnt);

         QStandardItem *aTempItem;
         QString tempstr;
         for(int i=0;i<RowCnt;++i)
         {
             salary temp_e=m_employees.Getemployee(m_row).m_salary.Getsalary(indexlist1[i]);

             tempstr=temp_e.e_id;

         }
         ui->label_num->setText(QString("薪资信息数：%1条").arg(RowCnt));
    }
}

5.打开文件

void MainWindow::on_actionOpen_triggered()  //打开文件
{   //打开一个文件
    QString curPath=QDir::currentPath();
    QString dlgTitle ="选择一个文件";
    QString filter="文本文件(*.txt);;所有文件(*.*)";
    QString aFileName=QFileDialog::getOpenFileName(this,dlgTitle,curPath,filter);

    if(aFileName.isEmpty())
    {
        ui->label_tips->setText("打开文件失败！");
        return ;
    }
    ui->label_tips->setText("正在打开文件。。。");
    //创建成功，打开文件
    QFile aFile(aFileName);

    if(!aFile.exists())  //文件不存在
    {
        ui->label_tips->setText("打开文件失败！");
        return;
    }
    if(!aFile.open(QIODevice::ReadOnly|QIODevice::Text)) //以文本方式打开
    {
        ui->label_tips->setText("打开文件失败！");
        return ;
    }

    m_employees=employeeinfotable(); //清空

    QTextStream aStream(&aFile);  //用文本流读取文件
    aStream.setCodec(QTextCodec::codecForName("system")); //显示汉字

    m_employees.ReadSalaryinfotable(aStream);
    aFile.close();  //关闭文件
    ui->label_tips->setText("文件读取成功！");

    show_EmployeeTable();
}

6.保存文件

void MainWindow::on_actionSave_triggered()
{   //保存一个文件
    QFile aFile("D:\\QTCode\\employeeMS\\data.txt");
    if(!aFile.open(QIODevice::WriteOnly|QIODevice::Text))  //保存为文本
    {
        ui->label_tips->setText("保存文件失败！");
        return;
    }
    QTextStream aStream(&aFile);//用文本流保存文件
    aStream.setCodec(QTextCodec::codecForName("system"));  //显示汉字

    m_employees.Saveemployeeinfotable(aStream);
    aFile.close();//关闭文件
    ui->label_tips->setText("文件已保存！");
}

7.文件另存为

void MainWindow::on_actionSaveAs_triggered()
{
    QString curPath=QDir::currentPath();
    QString dlgTitle = "另存一个文件";
    QString filter = "文本文件(*.txt);;所有文件(*.*)";
    QString aFileName=QFileDialog::getSaveFileName(this,dlgTitle,curPath,filter);
    if(aFileName.isEmpty())
    {
        ui->label_tips->setText("保存文件失败！");
        return ;
    }
    QFile aFile(aFileName);
    if(!aFile.open(QIODevice::WriteOnly|QIODevice::Text))
    {
        ui->label_tips->setText("保存文件失败！");
        return ;
    }

    QTextStream aStream(&aFile);
    aStream.setCodec(QTextCodec::codecForName("system"));

    m_employees.Saveemployeeinfotable(aStream);
    aFile.close();
    ui->label_tips->setText("文件保存成功！");
}

8.读取数据（默认路径）文章来源地址https://www.toymoban.com/news/detail-707788.html

void MainWindow::on_actionReadData_triggered()
{
    ui->label_tips->setText("正在读取数据。。。");
    QFile aFile("D:\\QTCode\\employeeMS\\data.txt");
    if(!aFile.exists())
    {
        ui->label_tips->setText("读取数据失败！");
        return ;
    }
    if(!aFile.open(QIODevice::ReadOnly | QIODevice::Text)) //以文本方式打开
    {

         ui->label_tips->setText("读取数据失败！");
        return;
    }

    QTextStream aStream(&aFile); //用文本流读取文件
    aStream.setCodec(QTextCodec::codecForName("system"));
    m_employees=employeeinfotable(); //清空

    m_employees.ReadSalaryinfotable(aStream);
    aFile.close();
    ui->label_tips->setText("数据读取成功!");
    show_EmployeeTable();
}

9. 获得选择信息索引

//为tableView控件的槽函数，函数参数为鼠标选中的表格索引
void MainWindow::on_tableView_clicked(const QModelIndex &index)
{
    if(m_View_kind==0)
    {
        m_row=index.row();
        ui->label_tips->setText(QString("已选中工号为%1 姓名为%2的职工")
                                .arg(m_employees.Getemployee(m_row).id)
                                .arg(m_employees.Getemployee(m_row).name));
    }
    else if(m_View_kind==1)
    {
        m_row1=index.row();
        ui->label_tips->setText(QString("已选中编号为%1 月份为%2的薪资信息")
                                .arg(m_employees.Getemployee(m_row).m_salary.Getsalary(m_row1).e_id)
                                .arg(m_employees.Getemployee(m_row).m_salary.Getsalary(m_row1).month));
    }
    else if(m_View_kind==2)
    {
        if(indexlist.isEmpty()) m_row=-1;
        else
        {
            m_row = indexlist[index.row()];
            ui->label_tips->setText(QString("已选中工号为%1 姓名为%2的职工")
                                    .arg(m_employees.Getemployee(m_row).id
                                    .arg(m_employees.Getemployee(m_row).name)));
        }
    }
    else if(m_View_kind==3)
    {
        if(indexlist1.isEmpty()) m_row=-1;
        else
        {
            m_row1=indexlist1[index.row()];
            ui->label_tips->setText(QString("已选中编号为%1 月份为%2的薪资信息")
                                    .arg(m_employees.Getemployee(m_row).m_salary.Getsalary(m_row1).e_id)
                                    .arg(m_employees.Getemployee(m_row).m_salary.Getsalary(m_row1).month));
        }
    }
}

10. 查询功能

void MainWindow::on_actionSelect_triggered()
{
    ui->label_tips->setText("正在查询。。。");
//  查询前清空索引列表
    indexlist.clear();
    indexlist1.clear();
//  在职工信息视图下
    if(m_View_kind==0||m_View_kind==2)
    {
        selectdialog sg1;
        sg1.setWindowTitle("职工信息查询");
        int ret=sg1.exec();

        if(ret==QDialog::Accepted)
        {
            int index =sg1.get_Comboboxindex(); //查询特征索引0为工号，1为姓名
            QString tempstr=sg1.get_Value();
//          遍历数据
            for(int i=0;i<m_employees.employeeNum();i++)
            {
                if(index==0)
                {
                    if(m_employees.Getemployee(i).id==tempstr)
                        indexlist.append(i);  //记录列表中
                }
                if(index==1)
                {

                        indexlist.append(i);  //记录列表中
                }
            }
//          判断列表是否为空
            if(indexlist.isEmpty())
                ui->label_tips->setText(QString("未找到%1为%2的职工信息")
                                        .arg(sg1.get_Comboboxtext()).arg(tempstr));
            else

    }
//  在薪资信息视图下
    else if(m_View_kind==1||m_View_kind==3)
    {
        selectdialog1 sg1;
        sg1.setWindowTitle("薪资信息查询");
        int ret =sg1.exec();

        if(ret==QDialog::Accepted)
        {
            int index=sg1.get_Comboboxindex();//查询特征索引0为月份，1为编号
            QString tempstr=sg1.get_Value(); //查询特征值

                if(index==0)
                {
                    if(QString::number(temp.month)==tempstr)

                }
            }
