effectiveMargins() [1/2]

void QBoxLayoutPrivate::effectiveMargins	(	int *	left,
		int *	top,
		int *	right,
		int *	bottom ) const

The purpose of this function is to make sure that widgets are not laid out outside its layout. E.g. the layoutItemRect margins are only meant to take of the surrounding margins/spacings. However, if the margin is 0, it can easily cover the area of a widget above it.
