This is the "bad" part of this patch... I took the number from `adjustWidgetSizes()`, where the width is defined as `const int maxWidth = width - style()->layoutSpacing(QSizePolicy::DefaultType, QSizePolicy::DefaultType, Qt::Horizontal) * 4;`. I found out that this corresponds to 12, because simply subtracting the `layoutSpacing()` from `parentWidget()->width()` did not work.

I need to change this (I know that simply hard-coding values is bad practice) but I couldn't figure out how.
