A fill symbol type, for rendering Polygon and MultiPolygon geometries.
A geometry is the spatial representation of a feature.
Layout item for node based polygon shapes.
~QgsLayoutItemPolygon() override
Contains settings and helpers relating to a render of a QgsLayoutItem.
virtual QgsGeometry clipPath() const
Returns the clipping path generated by this item, in layout coordinates.
virtual bool accept(QgsStyleEntityVisitorInterface *visitor) const
Accepts the specified style entity visitor, causing it to visit all style entities associated with th...
virtual QIcon icon() const
Returns the item's icon.
int type() const override
Returns a unique graphics item type identifier.
virtual QString displayName() const
Gets item display name.
QFlags< Flag > Flags

QgsLayoutItem::Flags itemFlags() const override
Returns the item's flags, which indicate how the item behaves.
virtual bool _removeNode(int nodeIndex)=0
Method called in removeNode.
virtual void _writeXmlStyle(QDomDocument &doc, QDomElement &elmt, const QgsReadWriteContext &context) const =0
Method called in writeXml.
virtual void _readXmlStyle(const QDomElement &elmt, const QgsReadWriteContext &context)=0
Method called in readXml.
virtual bool isValid() const =0
Must be reimplemented in subclasses.
virtual void _draw(QgsLayoutItemRenderContext &context, const QStyleOptionGraphicsItem *itemStyle=nullptr)=0
Method called in paint.
virtual bool _addNode(int nodeIndex, QPointF newNode, double radius)=0
Method called in addNode.
Base class for layouts, which can contain items such as maps, labels, scalebars, etc.
Definition qgslayout.h:49
The class is used as a container of context for various read/write operations on other objects.
An interface for classes which can visit style entity (e.g.
#define SIP_FACTORY
