Windows 10 - Adjust Container with Text Size

[maximus]

I have the following Interface on normal text size on Windows 10:

When the new Windows option "Make app 150% text bigger", it shows like this:

A lot of text go out of scope of the container they are using (QLabel, QPushButton, QHeaderView title) for example.
Is there a way to specify theses elements to use the minimum size to show the text? I have tried with MinimumExpending size policy, but usually that make it takes all the parent container space.

What I would like is to specify the Container (QLabel, QPushButton,..) to only take the space necessary to show the text at the current System font size.
Thanks!
