how can I obtain HWND of a class derived from QMainWindow

I currently have a windows API that requires a HWND hParentWnd. My question is how can I obtain HWND of a class derived from QMainWindow ?

You can use QWidget::effectiveWinId() or QWidget::winId(), this holds the HWND of the widget on Windows.

MainWindow w;
w.show();
HWND hWnd = (HWND) w.winId();
