static QgsLayoutItemRegistry * layoutItemRegistry()
Returns the application's layout item registry, used for layout item types.
QgsLayoutMultiFrame * createMultiFrame(int type, QgsLayout *layout) const
Creates a new instance of a layout multiframe given the multiframe type, and target layout.
Abstract base class for layout items with the ability to distribute the content to several frames (Qg...
bool writeXml(QDomElement &parentElement, QDomDocument &document, const QgsReadWriteContext &context, bool includeFrames=false) const
Stores the multiframe state in a DOM element.
virtual void finalizeRestoreFromXml()
Called after all pending items have been restored from XML.
bool readXml(const QDomElement &itemElement, const QDomDocument &document, const QgsReadWriteContext &context, bool includeFrames=false)
Sets the item state from a DOM element.
Base class for layouts, which can contain items such as maps, labels, scalebars, etc.
