Call MainWindow function from static one

column

Hello,

How to solve problem defined below? How to call nst() from st() ? I suppose I need to get pointer of class object that has nst() method.

.h

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    void nst();
    static void st();
private slots:


private:
    Ui::MainWindow *ui;
};

*.cpp

Ui::MainWindow *inst =NULL;


MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    inst=ui;
    i=this;
}

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


void MainWindow::nst()
{

}

void MainWindow::st()
{
if (inst != NULL) inst->nst();

}

That is certainly one way to do it. But you might ask yourself why you want to have a static function there in the first place.

BTW that is standard C++ and has nothing to do with Qt.

Hi,

First by reviewing your design. Trying to call a member function from a static method of the same class is sign of something fishy going on.
