QGraphicsLayout inherits QGraphicsLayoutItem which looks to have many 
functions for adjusting sizes:

void	setMaximumHeight ( qreal height )
void	setMaximumSize ( const QSizeF & size )
void	setMaximumSize ( qreal w, qreal h )
void	setMaximumWidth ( qreal width )
void	setMinimumHeight ( qreal height )
void	setMinimumSize ( const QSizeF & size )
void	setMinimumSize ( qreal w, qreal h )
void	setMinimumWidth ( qreal width )
void	setPreferredHeight ( qreal height )
void	setPreferredSize ( const QSizeF & size )
void	setPreferredSize ( qreal w, qreal h )
void	setPreferredWidth ( qreal width )
void	setSizePolicy ( const QSizePolicy & policy )
void	setSizePolicy ( QSizePolicy::Policy hPolicy, QSizePolicy::Policy 
vPolicy, QSizePolicy::ControlType controlType = QSizePolicy::DefaultType )

Have you tried any of those?
