Class: QgsLayoutItemAbstractMetadata¶

Stores metadata about one layout item class.

A companion class, QgsLayoutItemAbstractGuiMetadata, handles the GUI behavior of QgsLayoutItems.

Note

In C++ you can use QgsLayoutItemMetadata convenience class.

Note

This is an abstract class, with methods which must be implemented by a subclass.

The following methods must be implemented: createItem()

class qgis.core.QgsLayoutItemAbstractMetadata[source]¶

Bases: object

__init__(type: int, visibleName: str | None, visiblePluralName: str | None = '')

Constructor for QgsLayoutItemAbstractMetadata with the specified class type and visibleName.

The optional visiblePluralName argument can be used to specify a plural variant of the item type.

Parameters:

type (int)
visibleName (Optional[str])
visiblePluralName (Optional[str] = '')

__init__(a0: QgsLayoutItemAbstractMetadata)

Parameters:: a0 (QgsLayoutItemAbstractMetadata)

abstract createItem(self, layout: QgsLayout | None) → QgsLayoutItem | None[source]¶

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

Parameters:: layout (Optional[QgsLayout])
Return type:: Optional[QgsLayoutItem]

virtual resolvePaths(self, properties: Dict[str, Any], pathResolver: QgsPathResolver, saving: bool)[source]¶

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.

Parameters:

properties (Dict[str, Any])
pathResolver (QgsPathResolver)
saving (bool)

type(self) → int[source]¶

Returns the unique item type code for the layout item class.

Return type:: int

visibleName(self) → str[source]¶

Returns a translated, user visible name for the layout item class.
