用Qt和向量在行文件中发布读取

我在Qt中有一个问题，我正在运行代码来生成类对象的矢量并将它们输出到TableView。每当我运行代码时，它只读取文件的第一行。我把同样的代码，并改变TableView部分到一个标准的cout和一切工作正常。

showReservations::showReservations(QWidget *parent) :
QDialog(parent),
ui(new Ui::showReservations)
{
ui->setupUi(this);
std::vector<reservation> currReservations;
//Initalize the vector set
//Runs the ReadFlightSchedule with the vector set and returns a 1 if there is a
//failure and 0 if all is good
if (ReadReservations(currReservations) == 1)
{
    //This sets a label to red showing the user an error reading the file
    ui->label->setText("<font color = 'red'>Error Reading File! Oops</font>");
}
else {
    //hides the error label since the file read good.
    ui->label->hide();
    //Generates the column header names
    QStandardItemModel *model = new QStandardItemModel(currReservations.size(), 5, this);
    model->setHorizontalHeaderItem(0, new QStandardItem(QString("Flier Name")));
    model->setHorizontalHeaderItem(1, new QStandardItem(QString("Flight Date")));
    model->setHorizontalHeaderItem(2, new QStandardItem(QString("Flight Number")));
    model->setHorizontalHeaderItem(3, new QStandardItem(QString("Seat Designation")));
    model->setHorizontalHeaderItem(4, new QStandardItem(QString("Reservation ID")));
    //Sets the values from the vector sets to the appropriate column and row sets.
    for (int i = 0; i < currReservations.size(); i++)
    {
        model->setItem(i, 0, new QStandardItem(QString::fromStdString(currReservations[i].getName())));
        model->setItem(i, 1, new QStandardItem(QString::fromStdString(currReservations[i].getDate())));
        model->setItem(i, 2, new QStandardItem(QString::fromStdString(currReservations[i].getFlightNum())));
        model->setItem(i, 3, new QStandardItem(QString::fromStdString(currReservations[i].getSeatDesg())));
        model->setItem(i, 4, new QStandardItem(QString::fromStdString(currReservations[i].getReservationID())));
    }
    ui->tableView->setModel(model);
    ui->tableView->resizeColumnsToContents();
   }
}
showReservations::~showReservations()
{
delete ui;
}
//User Generated Functions
int showReservations::ReadReservations(std::vector<reservation>& Res)
{
std::ifstream flightFile;
std::string fName, lName, date, seatDes, flightNum;
int error = 0;
flightFile.open("reservations.txt");
if(!flightFile)
{
    //returns a error value if there is a problem reading the file
    error = 1;
    return error;
}
else
{
    //Start reading files and sticks them into a class object and sticks the object into the vector set        
    while (flightFile >> fName >> lName >> date >> flightNum >> seatDes)
    {
        reservation newRes(fName, lName, date, flightNum, seatDes);
        Res.push_back(newRes);
    }
}
flightFile.close();
return error;
}

工作的非qt代码:

int ReadReservations(std::vector<reservation>& Res);
int main(int argc, char **argv)
{
std::ifstream flightFile;
std::string name, date, seatDes, flightNum, line;
std::vector<reservation> Res;
flightFile.open("reservations.txt");
ReadReservations(Res);
for (int i = 0; i < Res.size(); i++)
{
    std::cout << Res[i].getName() << std::endl << Res[i].getDate() << std::endl << Res[i].getFlightNum() << std::endl << Res[i].getSeatDesg() << std::endl;
}
return 0;

}
int ReadReservations(std::vector<reservation>& Res)
{
 std::ifstream flightFile;
std::string fName, lName, date, seatDes, flightNum;
int error = 0;
flightFile.open("reservations.txt");
if(!flightFile)
{
    //returns a error value if there is a problem reading the file
    error = 1;
    return error;
}
else
{
    //Start reading files and sticks them into a class object and sticks the object into the vector set        
    while (flightFile >> fName >> lName >> date >> flightNum >> seatDes)
    {
        //flightFile >> fName >> lName >> date >> flightNum >> seatDes;
        reservation newRes(fName, lName, date, flightNum, seatDes);
        Res.push_back(newRes);
    }
}
flightFile.close();
return error;
}

我在另一个文件上有类似的工作。我就是不明白这个问题出在哪里。这是家庭作业
