overridevirtual

Applies an edit operation to the item.

Since: QGIS 3.22

Reimplemented from QgsAnnotationItem.

Definition at line 83 of file qgsannotationmarkeritem.cpp.

◆ boundingBox() [1/2]

QgsRectangle QgsAnnotationMarkerItem::boundingBox ( ) const

overridevirtual

Implements QgsAnnotationItem.

Definition at line 164 of file qgsannotationmarkeritem.cpp.

◆ boundingBox() [2/2]

QgsRectangle QgsAnnotationMarkerItem::boundingBox ( QgsRenderContext & context ) const

overridevirtual

Returns the bounding box of the item's geographic location, in the parent layer's coordinate reference system.

Reimplemented from QgsAnnotationItem.

Definition at line 169 of file qgsannotationmarkeritem.cpp.

◆ clone()

QgsAnnotationMarkerItem * QgsAnnotationMarkerItem::clone ( ) const

overridevirtual

Returns a clone of the item.

Ownership is transferred to the caller.

Implementations should include a call to copyCommonProperties() to copy the base class properties.

See also: copyCommonProperties()

Implements QgsAnnotationItem.

Definition at line 156 of file qgsannotationmarkeritem.cpp.

◆ symbol()

const QgsMarkerSymbol * QgsAnnotationMarkerItem::symbol ( ) const

Returns the symbol used to render the marker item.

See also: setSymbol()

Definition at line 198 of file qgsannotationmarkeritem.cpp.

◆ transientEditResults()

QgsAnnotationItemEditOperationTransientResults * QgsAnnotationMarkerItem::transientEditResults ( QgsAbstractAnnotationItemEditOperation * operation )

Reimplemented from QgsAnnotationItem.

Definition at line 114 of file qgsannotationmarkeritem.cpp.

◆ type()

QString QgsAnnotationMarkerItem::type ( ) const

overridevirtual

Returns a unique (untranslated) string identifying the type of item.

Implements QgsAnnotationItem.

Definition at line 35 of file qgsannotationmarkeritem.cpp.

◆ writeXml()

bool QgsAnnotationMarkerItem::writeXml	(	QDomElement &	element,
		QDomDocument &	document,
		const QgsReadWriteContext &	context
	)		const

overridevirtual

Writes the item's state into an XML element.

Implementations should include a call to writeCommonProperties() to store the base class properties.

See also: readXml(); writeCommonProperties()
