Constructor & Destructor Documentation

◆ QgsLayoutItemGuiMetadata()

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

		const QgsLayoutItemCreateFunc &	pfCreateFunc = `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.

Member Function Documentation

◆ createItem()

QgsLayoutItem * QgsLayoutItemGuiMetadata::createItem ( QgsLayout * layout )

overridevirtual

Creates an instance of the corresponding item type.

Reimplemented from QgsLayoutItemAbstractGuiMetadata.

Definition at line 165 of file qgslayoutitemguiregistry.cpp.

◆ createItemWidget()

QgsLayoutItemBaseWidget* QgsLayoutItemGuiMetadata::createItemWidget ( QgsLayoutItem * item )

inlineoverridevirtual

Definition at line 272 of file qgslayoutitemguiregistry.h.

◆ createNodeRubberBand()

QAbstractGraphicsShapeItem* QgsLayoutItemGuiMetadata::createNodeRubberBand ( QgsLayoutView * view )

inlineoverridevirtual

Creates a rubber band for use when creating layout node based items of this type.

Can return nullptr if no rubber band should be created. The default behavior is to return nullptr.

See also: createRubberBand()

Reimplemented from QgsLayoutItemAbstractGuiMetadata.

Definition at line 274 of file qgslayoutitemguiregistry.h.

◆ createRubberBand()

QgsLayoutViewRubberBand* QgsLayoutItemGuiMetadata::createRubberBand ( QgsLayoutView * view )

inlineoverridevirtual

Creates a rubber band for use when creating layout items of this type.

Can return nullptr if no rubber band should be created. The default behavior is to create a rectangular rubber band.

This is only called for additions which result from GUI operations - i.e. it is not called for items added from templates.

Reimplemented from QgsLayoutItemAbstractGuiMetadata.

Definition at line 170 of file qgslayoutitemguiregistry.cpp.

◆ newItemAddedToLayout() [2/2]

void QgsLayoutItemGuiMetadata::newItemAddedToLayout	(	QgsLayoutItem *	item,

	)

Called when a newly created item of the associated type has been added to a layout.

This is only called for additions which result from GUI operations - i.e. it is not called for items added from templates.

The properties map will be filled with any custom properties which were specified during the item creation.
