## Detailed Description

The QGraphicsPathItem class provides a path item that you can add to a QGraphicsScene.

To set the item's path, pass a QPainterPath to QGraphicsPathItem's constructor, or call the setPath() function. The path() function returns the current path.

QGraphicsPathItem uses the path to provide a reasonable implementation of boundingRect(), shape(), and contains(). The paint() function draws the path using the item's associated pen and brush, which you can set by calling the setPen() and setBrush() functions.

## Member Function Documentation

### QGraphicsPathItem::QGraphicsPathItem(QGraphicsItem *parent = Q_NULLPTR)

Constructs a QGraphicsPath. parent is passed to QAbstractGraphicsShapeItem's constructor.

See also QGraphicsScene::addItem().

### QGraphicsPathItem::QGraphicsPathItem(const QPainterPath &path, QGraphicsItem *parent = Q_NULLPTR)

Constructs a QGraphicsPath item using path as the default path. parent is passed to QAbstractGraphicsShapeItem's constructor.

See also QGraphicsScene::addItem().

### QGraphicsPathItem::~QGraphicsPathItem()

Destroys the QGraphicsPathItem.

### `[virtual]` QRectF QGraphicsPathItem::boundingRect() const

Reimplemented from QGraphicsItem::boundingRect().

### `[virtual]` bool QGraphicsPathItem::contains(const QPointF &point) const

Reimplemented from QGraphicsItem::contains().

### `[virtual]` bool QGraphicsPathItem::isObscuredBy(const QGraphicsItem *item) const

Reimplemented from QGraphicsItem::isObscuredBy().

### `[virtual]` QPainterPath QGraphicsPathItem::opaqueArea() const

Reimplemented from QGraphicsItem::opaqueArea().

### `[virtual]` void QGraphicsPathItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget = Q_NULLPTR)

Reimplemented from QGraphicsItem::paint().

### QPainterPath QGraphicsPathItem::path() const

Returns the item's path as a QPainterPath. If no item has been set, an empty QPainterPath is returned.

See also setPath().

### void QGraphicsPathItem::setPath(const QPainterPath &path)

Sets the item's path to be the given path.

See also path().

### `[virtual]` QPainterPath QGraphicsPathItem::shape() const

Reimplemented from QGraphicsItem::shape().

### `[virtual]` int QGraphicsPathItem::type() const

Reimplemented from QGraphicsItem::type().
