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。

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）

}

1. 显示职工信息（薪资信息同理）

void MainWindow::show_EmployeeTable()
{//不能修改ui->tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);can_change=false;//显示职工信息m_View_kind=0;
//    重置选择行m_row=-1;m_row1=-1;ui->label_title->setText("职工信息视图");employeeTableView->clear();employeeTableView->setColumnCount(7);  //7列//  表头
//  工号、姓名、年龄、入职日期、电话、住址、是否有工资信息QStringList templist;templist<<"工号"<<"姓名"<<"年龄"<<"入职日期"<<"电话"<<"住址"<<"是否有工资信息";employeeTableView->setHorizontalHeaderLabels(templist);int RowCnt = m_employees.employeeNum(); //行数（不含标题）employeeTableView->setRowCount(RowCnt);//遍历插入数据QStandardItem *aTempItem;  //临时的itemQString tempstr;for(int i=0;i<RowCnt;++i){employee temp_e=m_employees.Getemployee(i);tempstr=temp_e.id;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,0,aTempItem);tempstr=temp_e.name;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,1,aTempItem);tempstr=QString::number(temp_e.age);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,2,aTempItem);tempstr=temp_e.hiredate.toString("yyyy/MM/dd");aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,3,aTempItem);tempstr=temp_e.tele;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,4,aTempItem);tempstr=temp_e.address;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,5,aTempItem);if(temp_e.is_salary()) tempstr="否";else tempstr="是";aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,6,aTempItem);}ui->label_num->setText(QString("职工人数：%1人").arg(m_employees.employeeNum()));
//  设置内容为只读readonlydelegate* readOnlyDelegate = new readonlydelegate(this);ui->tableView->setItemDelegateForColumn(6,readOnlyDelegate);
}

void MainWindow::show_Table_e_changed()  //可以修改
{ui->tableView->setEditTriggers((QAbstractItemView::DoubleClicked));m_View_kind=0;m_row=-1;m_row1=-1;employeeTableView->clear();employeeTableView->setColumnCount(7);QStringList templist;templist<<"工号"<<"姓名"<<"年龄"<<"入职日期"<<"电话"<<"住址"<<"是否有工资信息";employeeTableView->setHorizontalHeaderLabels(templist);int RowCnt = m_employees.employeeNum();employeeTableView->setRowCount(RowCnt);QStandardItem *aTempItem;QString tempstr;for(int i=0;i<RowCnt;++i){employee temp_e=m_employees.Getemployee(i);tempstr=temp_e.id;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,0,aTempItem);tempstr=temp_e.name;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,1,aTempItem);tempstr=QString::number(temp_e.age);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,2,aTempItem);tempstr=temp_e.hiredate.toString("yyyy/MM/dd");aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,3,aTempItem);tempstr=temp_e.tele;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,4,aTempItem);tempstr=temp_e.address;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,5,aTempItem);if(temp_e.is_salary()) tempstr="否";else tempstr="是";aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,6,aTempItem);}ui->label_num->setText(QString("职工人数：%1人").arg(m_employees.employeeNum()));readonlydelegate* readOnlyDelegate = new readonlydelegate(this);ui->tableView->setItemDelegateForColumn(6,readOnlyDelegate);
}

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()
{ui->tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);can_change=false;//2-0  3-1if(m_View_kind==0||m_View_kind==2){m_View_kind=2;m_row=-1;m_row1=-1;ui->label_title->setText("职工信息视图");employeeTableView->clear();employeeTableView->setColumnCount(7);QStringList templist;templist<<"工号"<<"姓名"<<"年龄"<<"入职日期"<<"电话"<<"住址"<<"是否有工资信息";employeeTableView->setHorizontalHeaderLabels(templist);int RowCnt = indexlist.size();employeeTableView->setRowCount(RowCnt);QStandardItem *aTempItem;QString tempstr;for(int i=0;i<RowCnt;i++){employee temp_e=m_employees.Getemployee(indexlist[i]);tempstr=temp_e.id;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,0,aTempItem);tempstr=temp_e.name;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,1,aTempItem);tempstr=QString::number(temp_e.age);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,2,aTempItem);tempstr=temp_e.hiredate.toString("yyyy/MM/dd");aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,3,aTempItem);tempstr=temp_e.tele;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,4,aTempItem);tempstr=temp_e.address;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,5,aTempItem);if(temp_e.is_salary()) tempstr="否";else tempstr="是";aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,6,aTempItem);}ui->label_num->setText(QString("职工人数：%1人").arg(indexlist.size()));readonlydelegate* readOnlyDelegate = new readonlydelegate(this);ui->tableView->setItemDelegateForColumn(6,readOnlyDelegate);}else if(m_View_kind==1||m_View_kind==3){m_View_kind=3;m_row1=-1;ui->label_title->setText(QString("工号：%1  姓名：%2  薪资信息： ").arg(m_employees.Getemployee(m_row).id).arg(m_employees.Getemployee(m_row).name));employeeTableView->clear();employeeTableView->setColumnCount(10);QStringList templist;templist<<"编号"<<"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";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;aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,0,aTempItem);tempstr=QString::number(temp_e.month);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,1,aTempItem);tempstr=QString::number(temp_e.base_salary);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,2,aTempItem);tempstr=QString::number(temp_e.post_salary);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,3,aTempItem);tempstr=QString::number(temp_e.seniority_salary);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,4,aTempItem);tempstr=QString::number(temp_e.allowance);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,5,aTempItem);tempstr=QString::number(temp_e.post_allowance);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,6,aTempItem);tempstr=QString::number(temp_e.subsidy);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,7,aTempItem);tempstr=QString::number(temp_e.housing_allowance);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,8,aTempItem);tempstr=QString::number(temp_e.trans_allowance);aTempItem = new QStandardItem(tempstr);employeeTableView->setItem(i,9,aTempItem);}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）

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();
}

1. 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));}}
}

1. 查询功能

void MainWindow::on_actionSelect_triggered()
{ui->label_tips->setText("正在查询。。。");
