Constructor & Destructor Documentation

QgsLayoutItemMetadata::QgsLayoutItemMetadata ( int  type, const QString &  visibleName, const QgsLayoutItemCreateFunc &  pfCreate, const QgsLayoutItemPathResolverFunc &  pfPathResolver = nullptr  )

inline

Constructor for QgsLayoutItemMetadata with the specified class type and visibleName, and function pointers for the various item creation functions.

Definition at line 117 of file qgslayoutitemregistry.h.

Member Function Documentation

QgsLayoutItemCreateFunc QgsLayoutItemMetadata::createFunction ( ) const

inline

Returns the classes' item creation function.

Definition at line 128 of file qgslayoutitemregistry.h.

QgsLayoutItem* QgsLayoutItemMetadata::createItem ( QgsLayout *  layout )

inlineoverridevirtual

Creates a layout item of this class for a specified layout.

Implements QgsLayoutItemAbstractMetadata.

Definition at line 135 of file qgslayoutitemregistry.h.

QgsLayoutItemPathResolverFunc QgsLayoutItemMetadata::pathResolverFunction ( ) const

inline

Returns the classes' path resolver function.

Definition at line 133 of file qgslayoutitemregistry.h.

void QgsLayoutItemMetadata::resolvePaths ( QVariantMap &  properties, const QgsPathResolver &  pathResolver, bool  saving  )

inlineoverridevirtual

Resolve paths in the item's properties (if there are any paths).

When saving is true, paths are converted from absolute to relative, when saving is false, paths are converted from relative to absolute. This ensures that paths in project files can be relative, but in item instances the paths are always absolute.

Reimplemented from QgsLayoutItemAbstractMetadata.
