I assume that you want to fit your width and height to the minimum and maximum size hint

Qt Code: 
  1. if (your_width < minimumSizeHint().width())
  2. {
  3.     your_width = minimumSizeHint().width();
  4. }
  5. else if (your_width > maximumSizeHint().width))
  6. {
  7.    your_width = maximumSizeHint().width();
  8. }
  9.  
  10. if (your_height < minimumSizeHint().height())
  11. {
  12.     your_height = minimumSizeHint().height();
  13. }
  14. else if (your_height > maximumSizeHint().height())
  15. {
  16.     your_height = maximumSizeHint().height();
  17. }
  18.  
  19. resize(your_width, your_height);
