Class: QgsAnnotationItemAbstractGuiMetadata¶

Stores GUI metadata about one annotation item class.

This is a companion to QgsAnnotationItemAbstractMetadata, storing only the components related to the GUI behavior of an annotation item.

Note

In C++ you can use QgsAnnotationItemGuiMetadata convenience class.

Added in version 3.22.

Methods

`flags`	Returns item flags.
`groupId`	Returns the item group ID, if set.
`type`	Returns the unique item type code for the annotation item class.
`visibleName`	Returns a translated, user visible name identifying the corresponding annotation item.

Virtual Methods

In PyQGIS, only methods marked as virtual can be safely overridden in a Python subclass of QgsAnnotationItemAbstractGuiMetadata. See the FAQ for more details.

`createItem`	Creates an instance of the corresponding item type.
`createItemWidget`	Creates a configuration widget for an item of this type.
`createMapTool`	Creates a map tool for a creating a new item of this type.
`creationIcon`	Returns an icon representing creation of the annotation item type.
`newItemAddedToLayer`	Called when a newly created item of the associated type has been added to a layer.

class qgis.gui.QgsAnnotationItemAbstractGuiMetadata[source]¶

Bases: object

__init__(type: str | None, visibleName: str | None, groupId: str | None = '', flags: Qgis.AnnotationItemGuiFlags | Qgis.AnnotationItemGuiFlag = Qgis.AnnotationItemGuiFlags())

Constructor for QgsAnnotationItemAbstractGuiMetadata with the specified class type.

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

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

Parameters:

type (Optional[str])
visibleName (Optional[str])
groupId (Optional[str] = '')
flags (Union[Qgis.AnnotationItemGuiFlags, Qgis.AnnotationItemGuiFlag] = Qgis.AnnotationItemGuiFlags())

__init__(a0: QgsAnnotationItemAbstractGuiMetadata)

Parameters:: a0 (QgsAnnotationItemAbstractGuiMetadata)

virtual createItem(self) → QgsAnnotationItem | None[source]¶

Creates an instance of the corresponding item type.

Return type:: Optional[QgsAnnotationItem]

virtual createItemWidget(self, item: QgsAnnotationItem | None) → QgsAnnotationItemBaseWidget | None[source]¶

Creates a configuration widget for an item of this type. Can return None if no configuration GUI is required.

Parameters:: item (Optional[QgsAnnotationItem])
Return type:: Optional[QgsAnnotationItemBaseWidget]

virtual createMapTool(self, canvas: QgsMapCanvas | None, cadDockWidget: QgsAdvancedDigitizingDockWidget | None) → QgsCreateAnnotationItemMapToolInterface | None[source]¶

Creates a map tool for a creating a new item of this type.

May return None if no map tool is available for creating the item.

Parameters:

canvas (Optional[QgsMapCanvas])
cadDockWidget (Optional[QgsAdvancedDigitizingDockWidget])

Return type:

Optional[QgsCreateAnnotationItemMapToolInterface]

virtual creationIcon(self) → QIcon[source]¶

Returns an icon representing creation of the annotation item type.

Return type:: QIcon

flags(self) → Qgis.AnnotationItemGuiFlags[source]¶

Returns item flags.

Return type:: Qgis.AnnotationItemGuiFlags

groupId(self) → str[source]¶

Returns the item group ID, if set.

Return type:: str

virtual newItemAddedToLayer(self, item: QgsAnnotationItem | None, layer: QgsAnnotationLayer | None)[source]¶

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

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

Parameters:

item (Optional[QgsAnnotationItem])
layer (Optional[QgsAnnotationLayer])

type(self) → str[source]¶

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

Return type:: str

visibleName(self) → str[source]¶

Returns a translated, user visible name identifying the corresponding annotation item.

Return type:: str
