So i have a `QGroupBox` with a vertical layout inside of it.  

There is a `QWidget` container at top(blue).

I have used `setContentsMargins(0,0,0,0)` for both the `QGroupBox` and the `QWidget` container yet no matter what i do i cannot get the `QWidget` container to be at **(0,0)** in the top left of the groupbox. Ive marked in red the spacing i want to remove.
