[SOLVED] How to save information to text file.
-
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(mFileName); if (!mFile.open(QFile::WriteOnly | QFile::Text)) { 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
Paawan

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