cannot share the database connection!!!!

[spirit]

of course.
so it should look like

class parathiro : public QMainWindow
{
    Q_OBJECT
public:
    parathiro(QWidget *parent = 0, database *d);

class parathiro : public QMainWindow
{
    Q_OBJECT
public:
    parathiro(QWidget *parent = 0, database *d);
