[jpoz]

hi
i have a problem on QFileDialog,i want to save data from QTableWidget ,here is my function for saving but i am getting error!Please help me on this...

void AddressBook::on_actionSave_triggered()
 {
 
     QString fileName = QFileDialog::getSaveFileName(
        this );
 
     if (!fileName.isEmpty()) {
        tableWidget->writeToFile(fileName);
     }
 }

void AddressBook::on_actionSave_triggered()
 {

     QString fileName = QFileDialog::getSaveFileName(
        this );

     if (!fileName.isEmpty()) {
        tableWidget->writeToFile(fileName);

where is writeToFile located? QTableWidget doesn't have such method.

He probably missed to implement the writeToFile function from AddressWidget example

void AddressWidget::writeToFile(QString fileName)
 {
     QFile file(fileName);
 
     if (!file.open(QIODevice::WriteOnly)) {
         QMessageBox::information(this, tr("Unable to open file"), file.errorString());
         return;
     }
 
     QList< QPair<QString, QString> > pairs = table->getList();
     QDataStream out(&file);
     out << pairs;
 }

void AddressWidget::writeToFile(QString fileName)
 {
     QFile file(fileName);

     if (!file.open(QIODevice::WriteOnly)) {
         QMessageBox::information(this, tr("Unable to open file"), file.errorString());
         return;
     }

     QList< QPair<QString, QString> > pairs = table->getList();
     QDataStream out(&file);
     out << pairs;
 }
