QGraphicsLineItem::~QGraphicsLineItem()

Destroys the QGraphicsLineItem.

QRectF QGraphicsLineItem::boundingRect() const [virtual]

Reimplemented from QGraphicsItem::boundingRect().

bool QGraphicsLineItem::contains(const QPointF & point) const [virtual]

Reimplemented from QGraphicsItem::contains().

bool QGraphicsLineItem::isObscuredBy(const QGraphicsItem * item) const [virtual]

Reimplemented from QGraphicsItem::isObscuredBy().

QLineF QGraphicsLineItem::line() const

Returns the item's line, or a null line if no line has been set.

void QGraphicsLineItem::setLine(qreal x1, qreal y1, qreal x2, qreal y2)

This is an overloaded function.

Sets the item's line to be the line between (x1, y1) and (x2, y2).

This is the same as calling setLine(QLineF(x1, y1, x2, y2)).

void QGraphicsLineItem::setPen(const QPen & pen)

Sets the item's pen to pen. If no pen is set, the line will be painted using a black solid 0-width pen.
