invalid use of qualified-name MainWindow::on_save_clicked()

Any ideas as to why this has happened?

Hi,

@
void MainWindow::on_save_clicked(); { <- Why do you have semi-colon here ?

    // creating directory upon run for user input

    QDir mDir;
    mDir.mkpath("C:/Monice/BW");

    QString MBW = ("C:/Monice/BW/MBW.txt");

    QFile mFile&#40;MBW&#41;;

    if (mFile.open(QIODevice::WriteOnly))
    {
        QTextStream out(&mFile);
        out << ui->lineEdit->text();
    }

}

} <- this one is not at its place
@

Hope it helps

by not at its plae you mean not needed, i dont understand. now that i have removed the semicolon (super anoyyed about that xD) the error is that the the { is expected after another { and a function definition is not allowed before the }

@
void MainWindow::on_save_clicked()
{

    // creating directory upon run for user input

    QDir mDir;
    mDir.mkpath("C:/Monice/BW");

    QString MBW = ("C:/Monice/BW/MBW.txt");

    QFile mFile&#40;MBW&#41;;

    if (mFile.open(QIODevice::WriteOnly))
    {
        QTextStream out(&mFile);
        out << ui->lineEdit->text();
    }

}

MainWindow::~MainWindow()
{
delete ui;
}

error occurs at frist and last } symbol

Hi, I think with "not at its place" he meant you need to put it at the right place, ant not delete it. :D
i think you should move the "}" before the line
@
void MainWindow::on_save_clicked() {
@
because it looks like the closing bracket of your constructor?

If you format your code properly something like that is easier to spot,
Qt Creator can at least indent the code for you: select the code and press ctrl+I

Hi, your original post should look like that:

@
MainWindow::MainWindow(QWidget *parent):
QMainWindow(parent),
ui(new Ui::MainWindow)

{
ui->setupUi(this);

//display network interfaces
QList<QNetworkInterface> list = QNetworkInterface::allInterfaces();

// each interface is allocated one after the other in a list

foreach (QNetworkInterface mon, list)

//adding the list to be shown in the interface combobox
{
ui->comboBox_Interface->addItem(mon.name());
}

// a for loop that counts from 50-90 in multiples of 5
for (int i = 50; i <= 90; i += 5)
//selecting the combox alert to diplay the figures 50-90 with a % symbol
{
    ui->comboBox_Alert->addItem(QString::number(i) + "%");
}

} // <---- END CONSTRUCTOR
void MainWindow::on_save_clicked() // <--- no ; here
{ // <----

    // creating directory upon run for user input

    QDir mDir;
    mDir.mkpath("C:/Monice/BW");

    QString MBW = ("C:/Monice/BW/MBW.txt");

    QFile mFile&#40;MBW&#41;;

    if (mFile.open(QIODevice::WriteOnly))
    {
        QTextStream out(&mFile);
        out << ui->lineEdit->text();
    }

}

MainWindow::~MainWindow()
{
delete ui;
}
