AnnotationItemEditOperationResult
Results from an edit operation on an annotation item.
Definition qgis.h:1836
Abstract base class for annotation item edit operations.
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 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 * transientEditResults(QgsAbstractAnnotationItemEditOperation *operation)
Retrieves the results of a transient (in progress) edit operation on the item.
virtual QList< QgsAnnotationItemNode > nodes() const
Returns the nodes for the item, used for editing the item.
virtual Qgis::AnnotationItemEditOperationResult applyEdit(QgsAbstractAnnotationItemEditOperation *operation)
Applies an edit operation to the item.
An annotation item which renders a fill symbol for a polygon geometry.
~QgsAnnotationPolygonItem() override
Curve polygon geometry type.
Base class for feedback objects to be used for cancellation of something running in a worker thread.
Definition qgsfeedback.h:45
A fill symbol type, for rendering Polygon and MultiPolygon 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.
