keeping aspect ratio while resizing

Hi to all,
I have a QMainWindow with a custom central widget. I set a background image for that
central widget.
I would keep the aspect ratio while resizing to preserve the aspect ratio of the background image.
How can I do?

Best Regards,
Franco

Is there anyone? I got too many replies

Will an implementation of QWidget::heightForWidth(int) help you? If not, then maybe a custom layout manager.
