QWidget with fixed width height ratio

Hi,

I have implemented my own widget plugin for Qt Designer. When resizing the widget in Qt Designer I want the width height ratio to be fix (1:1). I have reimplementet the resizeEvent doing a resize to 1:1. But I'm not really satisfied with this solution.

Is there a more appropriate way to keep the ratio?

Thank you in advance
