Class: QgsLayoutItemRegistry¶

class qgis.core.QgsLayoutItemRegistry¶

Bases: PyQt5.QtCore.QObject

Registry of available layout item types.

QgsLayoutItemRegistry is not usually directly created, but rather accessed through QgsApplication.layoutItemRegistry().

A companion class, QgsLayoutItemGuiRegistry, handles the GUI behavior of layout items.

New in version 3.0.

QgsLayoutItemRegistry(parent: QObject = None) Creates a new empty item registry.

QgsLayoutItemRegistry is not usually directly created, but rather accessed through QgsApplication.layoutItemRegistry().

addLayoutItemType(self, metadata: QgsLayoutItemAbstractMetadata) → bool¶

Registers a new layout item type. Takes ownership of the metadata instance.

addLayoutMultiFrameType()

Parameters: metadata (QgsLayoutItemAbstractMetadata) –
Return type: bool

addLayoutMultiFrameType(self, metadata: QgsLayoutMultiFrameAbstractMetadata) → bool¶

Registers a new layout multiframe type. Takes ownership of the metadata instance.

addLayoutItemType()

Parameters: metadata (QgsLayoutMultiFrameAbstractMetadata) –
Return type: bool

childEvent(self, QChildEvent)¶

connectNotify(self, QMetaMethod)¶

createItem(self, type: int, layout: QgsLayout) → QgsLayoutItem¶

Creates a new instance of a layout item given the item type, and target layout.

See also

createMultiFrame()

Parameters

type (int) –
layout (QgsLayout) –

Return type

QgsLayoutItem

createMultiFrame(self, type: int, layout: QgsLayout) → QgsLayoutMultiFrame¶

Creates a new instance of a layout multiframe given the multiframe type, and target layout.

createItem()

Parameters

type (int) –
layout (QgsLayout) –

Return type

QgsLayoutMultiFrame

customEvent(self, QEvent)¶

disconnectNotify(self, QMetaMethod)¶

isSignalConnected(self, QMetaMethod) → bool¶

itemMetadata(self, type: int) → QgsLayoutItemAbstractMetadata¶

Returns the metadata for the specified item type. Returns None if a corresponding type was not found in the registry.

See also

multiFrameMetadata()

Parameters: type (int) –
Return type: QgsLayoutItemAbstractMetadata

itemTypes(self) → Dict[int, str]¶

Returns a map of available item types to translated name.

Return type: Dict[int, str]

multiFrameMetadata(self, type: int) → QgsLayoutMultiFrameAbstractMetadata¶

Returns the metadata for the specified multiframe type. Returns None if a corresponding type was not found in the registry.

See also

itemMetadata()

Parameters: type (int) –
Return type: QgsLayoutMultiFrameAbstractMetadata

multiFrameTypeAdded¶

Emitted whenever a new multiframe type is added to the registry, with the specified type and visible name. [signal]

Parameters

type (int) –
name (str) –

populate(self) → bool¶

Populates the registry with standard item types. If called on a non-empty registry then this will have no effect and will return False.

Return type: bool

receivers(self, PYQT_SIGNAL) → int¶

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

Resolve paths in properties of a particular symbol layer. This normally means converting relative paths to absolute paths when loading and converting absolute paths to relative paths when saving.

Parameters

properties (Dict[str) –
pathResolver (QgsPathResolver) –
saving (bool) –

sender(self) → QObject¶

timerEvent(self, QTimerEvent)¶

typeAdded¶

Emitted whenever a new item type is added to the registry, with the specified type and visible name. [signal]

Parameters

type (int) –
name (str) –
