how to access the Member Variable of MainWindow from another class?

[mammaiap]

Hi Friends,

i am facing the following problem...

how i can access the variable which is declared in the mainwindow class from some other class?


code snippet:

class MainWindow : public QMainWindow
{
    Q_OBJECT
 
public:
    MainWindow(QWidget *parent = 0);
    ~MainWindow();
public:
         QList<int> cno_airfoilgeom;
        QList<int> sno_airfoilgeom;
 
};
 
class AirfoilGeomTab : public QWidget
{
    Q_OBJECT
 
public:
    AirfoilGeomTab(QWidget *parent = 0);
 
};
 
i wanted to use the "cno_airfoilgeom" variable in the "AirfoilGeomTab"  constructor...
 
AirfoilGeomTab::AirfoilGeomTab(QWidget *parent)
    : QWidget(parent)  
{
 
// i wanted to use the "cno_airfoilgeom" variable here
 
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    MainWindow(QWidget *parent = 0);
    ~MainWindow();
public:
         QList<int> cno_airfoilgeom;
        QList<int> sno_airfoilgeom;

};

class AirfoilGeomTab : public QWidget
{
    Q_OBJECT

public:
    AirfoilGeomTab(QWidget *parent = 0);

};

i wanted to use the "cno_airfoilgeom" variable in the "AirfoilGeomTab"  constructor...

AirfoilGeomTab::AirfoilGeomTab(QWidget *parent)
    : QWidget(parent)  
{

// i wanted to use the "cno_airfoilgeom" variable here

}
