Constructor & Destructor Documentation

◆ QgsLayoutItemGuiMetadata()

QgsLayoutItemGuiMetadata::QgsLayoutItemGuiMetadata	(	int	type,
		const QString &	visibleName,
		const QIcon &	creationIcon,
		const QgsLayoutItemWidgetFunc &	pfWidget = `nullptr`,
		const QgsLayoutItemRubberBandFunc &	pfRubberBand = `nullptr`,

	)

inline

Constructor for QgsLayoutItemGuiMetadata with the specified class type and creationIcon, and function pointers for the various configuration widget creation functions.

visibleName should be set to a translated, user visible name identifying the corresponding layout item.

An optional groupId can be set, which allows grouping of related layout item classes. See QgsLayoutItemGuiMetadata for details.

If isNodeBased is true, then the corresponding item is a node based item.
