QGraphicsGridLayout::~QGraphicsGridLayout () [virtual]

Destroys the QGraphicsGridLayout object.

void QGraphicsGridLayout::addItem ( QGraphicsLayoutItem * item, int row, int column, int rowSpan, int columnSpan, Qt::Alignment alignment = 0 )

Adds item to the grid on row and column. You can specify a rowSpan and columnSpan and an optional alignment.

void QGraphicsGridLayout::addItem ( QGraphicsLayoutItem * item, int row, int column, Qt::Alignment alignment = 0 )

Adds item to the grid on row and column. You can specify an optional alignment for item.

Qt::Alignment QGraphicsGridLayout::alignment ( QGraphicsLayoutItem * item ) const
