Detailed Description

The QAbstractGraphicsShapeItem class provides a common base for all path items.

This class does not fully implement an item by itself; in particular, it does not implement boundingRect() and paint(), which are inherited by QGraphicsItem.

You can subclass this item to provide a simple base implementation of accessors for the item's pen and brush.

See also QGraphicsRectItem, QGraphicsEllipseItem, QGraphicsPathItem, QGraphicsPolygonItem, QGraphicsTextItem, QGraphicsLineItem, QGraphicsPixmapItem, and Graphics View Framework.

Member Function Documentation

QAbstractGraphicsShapeItem::QAbstractGraphicsShapeItem ( QGraphicsItem * parent = 0 )

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

QAbstractGraphicsShapeItem::~QAbstractGraphicsShapeItem ()

Destroys a QAbstractGraphicsShapeItem.

QBrush QAbstractGraphicsShapeItem::brush () const

Returns the item's brush, or an empty brush if no brush has been set.

See also setBrush().

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

Reimplemented from QGraphicsItem::isObscuredBy().

QPainterPath QAbstractGraphicsShapeItem::opaqueArea () const [virtual]

Reimplemented from QGraphicsItem::opaqueArea().

QPen QAbstractGraphicsShapeItem::pen () const

Returns the item's pen. If no pen has been set, this function returns QPen(), a default black solid line pen with 0 width.

See also setPen().

void QAbstractGraphicsShapeItem::setBrush ( const QBrush & brush )

Sets the item's brush to brush.

The item's brush is used to fill the item.

If you use a brush with a QGradient, the gradient is relative to the item's coordinate system.

See also brush().

void QAbstractGraphicsShapeItem::setPen ( const QPen & pen )

Sets the pen for this item to pen.

The pen is used to draw the item's outline.

See also pen().
