QSettings error

[darlene]

Hi! This is my first time to program in Qt and having problems with QSettings. I followed a code i saw online

private:
    QSettings settings;

private:
    QSettings settings;

To copy to clipboard, switch view to plain text mode 

and adding this to the constructor:

MainWindow::MainWindow(QWidget *parent) :
    ...
    settings("Contemposoft", "SimpleTextEdit")

MainWindow::MainWindow(QWidget *parent) :
    ...
    settings("Contemposoft", "SimpleTextEdit")

To copy to clipboard, switch view to plain text mode 

but i get the folowing error:

no match for call to '(QSettings) (const char [5], const char [8])'

thanks

That error message does not match the code lines you posted (it implies you used strings of 5 and 8 characters).

The error arises because you have put the attempt to initialize "settings" inside the constructor (where it is already default constructed) rather than in the constructor initialization list (where you have the opportunity to dictate how to construct it).

class MainWindow: public QMainWindow {
    Q_OBJECT
public:
    MainWindow(QWidget *p = 0): QMainWindow(p),
        settings("Contemposoft", "SimpleTextEdit")
    {
      // up there ^^^^ , not in here
    }
...
private:
    QSettings settings;
};

class MainWindow: public QMainWindow {
    Q_OBJECT
public:
    MainWindow(QWidget *p = 0): QMainWindow(p),
        settings("Contemposoft", "SimpleTextEdit")
    {
      // up there ^^^^ , not in here
    }
...
private:
    QSettings settings;
};
