Abstract base class for curved geometry type.
 
virtual QList< QgsAnnotationItemNode > nodes() const
Returns the nodes for the item, used for editing the item.
 
The class is used as a container of context for various read/write operations on other objects.
 
void setGeometry(QgsCurve *geometry)
Sets the geometry of the item.
 
virtual bool readXml(const QDomElement &element, const QgsReadWriteContext &context)=0
Reads the item's state from the given DOM element.
 
Contains information about the context of a rendering operation.
 
virtual QgsAnnotationItem * clone()=0
Returns a clone of the item.
 
A rectangle specified with double values.
 
AnnotationItemEditOperationResult
Results from an edit operation on an annotation item.
 
virtual bool writeXml(QDomElement &element, QDomDocument &document, const QgsReadWriteContext &context) const =0
Writes the item's state into an XML element.
 
Base class for feedback objects to be used for cancellation of something running in a worker thread.
 
A line symbol type, for rendering LineString and MultiLineString geometries.
 
Abstract base class for annotation item edit operations.
 
const QgsCurve * geometry() const
Returns the geometry of the item.
 
virtual void render(QgsRenderContext &context, QgsFeedback *feedback)=0
Renders the item to the specified render context.
 
virtual Qgis::AnnotationItemEditOperationResult applyEdit(QgsAbstractAnnotationItemEditOperation *operation)
Applies an edit operation to the item.
 
virtual QgsRectangle boundingBox() const =0
Returns the bounding box of the item's geographic location, in the parent layer's coordinate referenc...
 
An annotation item which renders a line symbol along a line geometry.
 
virtual QgsAnnotationItemEditOperationTransientResults * transientEditResults(QgsAbstractAnnotationItemEditOperation *operation)
Retrieves the results of a transient (in progress) edit operation on the item.
 
Abstract base class for annotation items which are drawn with QgsAnnotationLayers.
 
Encapsulates the transient results of an in-progress annotation edit operation.
 
virtual QString type() const =0
Returns a unique (untranslated) string identifying the type of item.
