AnnotationItemEditOperationResult
Results from an edit operation on an annotation item.
Definition qgis.h:2351
QFlags< AnnotationItemFlag > AnnotationItemFlags
Annotation item flags.
Definition qgis.h:2302
Abstract base class for annotation item edit operations.
Encapsulates the context for an annotation item edit operation.
Encapsulates the transient results of an in-progress annotation edit operation.
Abstract base class for annotation items which are drawn with QgsAnnotationLayers.
virtual bool writeXml(QDomElement &element, QDomDocument &document, const QgsReadWriteContext &context) const =0
Writes the item's state into an XML element.
virtual QList< QgsAnnotationItemNode > nodesV2(const QgsAnnotationItemEditContext &context) const
Returns the nodes for the item, used for editing the item.
virtual QString type() const =0
Returns a unique (untranslated) string identifying the type of item.
virtual void render(QgsRenderContext &context, QgsFeedback *feedback)=0
Renders the item to the specified render context.
virtual QgsAnnotationItemEditOperationTransientResults * transientEditResultsV2(QgsAbstractAnnotationItemEditOperation *operation, const QgsAnnotationItemEditContext &context)
Retrieves the results of a transient (in progress) edit operation on the item.
virtual Qgis::AnnotationItemFlags flags() const
Returns item flags.
virtual Qgis::AnnotationItemEditOperationResult applyEditV2(QgsAbstractAnnotationItemEditOperation *operation, const QgsAnnotationItemEditContext &context)
Applies an edit operation to the item.
An annotation item which renders a line symbol along a line geometry.
~QgsAnnotationLineItem() override
Abstract base class for curved geometry type.
Definition qgscurve.h:35
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition qgsfeedback.h:44
A line symbol type, for rendering LineString and MultiLineString geometries.
The class is used as a container of context for various read/write operations on other objects.
A rectangle specified with double values.
Contains information about the context of a rendering operation.
