[SOLVED] How to save information to text file.

Paawan

Hi All,

One of my assignment questions asks me to display a screen where a user enters software name, date of release and if it is recommended or not. Then store the information.

I made a UI class derived from QDialog that display the fields.

I then made a "Software" class that has the three variables.

@ software::software(QString name, QDate rdate, QString recommend){

setName(name);
setDate(rdate);
setRecommend(recommend);

}@

I then made a software writer class which takes the "Software" class object and writes the info to a text file.

@
SoftwareWriter::SoftwareWriter(software *mySoftware){

QString mFileName = "F:/mySoftware.txt";
QFile mFile&#40;mFileName&#41;;

if (!mFile.open(QFile::WriteOnly | QFile::Text&#41;)

{
    qDebug()<< "Cannot open File";
    return;
}
QTextStream out(&mFile);

out<< mySoftware->getName();
out<< " ";
out << mySoftware->getRecommend();
out<< " ";
out <<mySoftware->getDate().toString();

mFile.flush();
mFile.close();

@

I have added a "Add" button the the UI class. Which when clicked triggers

@
void InputGUI::on_pbAdd_clicked()
{
name = ui->leName->text();
rdate = ui->deDate->date();
recommend = "No";

if (ui->cb->isChecked()){
    recommend = "Yes";
}
software * mySoftware = new software(name, rdate, recommend);

SoftwareWriter write(mySoftware);

}

@

My problem is whenever I click on the "Add" button a new file is created instead of the same file being used to store the information.

How do I fix that problem?

Thanks and Regards

Hi,

Look again at the "OpenMode":http://qt-project.org/doc/qt-5/qiodevice.html#OpenModeFlag-enum it's just there.
