Remove Qt widget layout's margins

Question

I want to remove the spacing marked as red lines in the screenshot. I set layout's contents margins to (0,0,0,0), re-sized parent widget to minimum but still can not get rid of those spaces. This only happens on Mac. Looking for some help. Thanks in advance!

Answer 1

As nnb told, welcome to the weird size policies on mac. But you can wrap layout to widget and crop margins.
