Constructor & Destructor Documentation

◆ QgsLayoutItemMetadata()

QgsLayoutItemMetadata::QgsLayoutItemMetadata ( int  type,
const QString &  visibleName,
const QString &  visiblePluralName,
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.

The visiblePluralName argument is used to specify a plural variant of the item type.

Member Function Documentation

◆ createFunction()

QgsLayoutItemCreateFunc QgsLayoutItemMetadata::createFunction ( ) const
inline

Returns the classes' item creation function.

Definition at line 156 of file qgslayoutitemregistry.h.

◆ createItem()

QgsLayoutItem * QgsLayoutItemMetadata::createItem ( QgsLayout layout)
inlineoverridevirtual

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

Implements QgsLayoutItemAbstractMetadata.

Definition at line 163 of file qgslayoutitemregistry.h.

◆ pathResolverFunction()

QgsLayoutItemPathResolverFunc QgsLayoutItemMetadata::pathResolverFunction ( ) const
inline

Returns the classes' path resolver function.

Definition at line 161 of file qgslayoutitemregistry.h.

◆ resolvePaths()

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.
