I'm trying to overwrite an existing file using Qt. Since QFileDialog::getSaveFileName will always replace the selected file if it already exists, I've tried creating a custom QFileDialog in over to get to my goal so I used what has been suggested in this link but it seems not to work...
What I've tried so far:
QFileDialog diag(this);
diag.setFileMode(QFileDialog::AnyFile);
diag.setNameFilter(tr("Test (*.tst)"));
diag.setAcceptMode(QFileDialog::AcceptSave);
diag.exec();
QStringList namefile = diag.selectedFiles();
QFile file(namefile[0]);
if(file.open(QIODevice::WriteOnly | QIODevice::Text)){
QTextStream stream(&file);
stream << ui->lineEdit->text() << endl;
}
file.close();
result:
