filterFeatures()

Return type

str

filterFeatures(self) → bool

Returns True if a feature filter is active on the attribute table.

featureFilter()

Return type

bool

filterToAtlasFeature(self) → bool

Returns True if the table is set to only show features which intersect the current atlas feature.

Return type

bool

finalizeRestoreFromXml(self)
icon(self) → QIcon
Return type

QIcon

isSignalConnected()
map(self) → QgsLayoutItemMap

Returns the layout map whose extents are controlling the features shown in the table. The extents of the map are only used if displayOnlyVisibleFeatures() is True.

setMap()

Return type

QgsLayoutItemMap

maximumNumberOfFeatures(self) → int

Returns the maximum number of features to be shown by the table.

Return type

int

readObjectPropertiesFromElement()
readPropertiesFromElement(self, itemElem: QDomElement, doc: QDomDocument, context: QgsReadWriteContext) → bool
Parameters
Return type

bool

recalculateTableSize()
receivers()
refreshDataDefinedProperty(self, property: QgsLayoutObject.DataDefinedProperty = QgsLayoutObject.AllProperties)
Parameters

property (QgsLayoutObject.DataDefinedProperty = QgsLayoutObject.AllProperties) –

relationId(self) → str

Returns the relation id which the table displays child features from.

source()

Note

Only used if table source() is set to RelationChildren.

Return type

str

resetColumns(self)

Resets the attribute table’s columns to match the vector layer’s fields.

setVectorLayer()

rowRange()
rowsVisible()
sender()
senderSignalIndex()
setDisplayOnlyVisibleFeatures(self, visibleOnly: bool)

Sets the attribute table to only show features which are visible in a map item. Changing this setting forces the table to refetch features from its vector layer, and may result in the table changing size to accommodate the new displayed feature attributes.

See also

setMap()

Parameters

visibleOnly (bool) –

setDisplayedFields(self, fields: Iterable[str], refresh: bool = True)

Sets the attributes to display in the table.

Parameters
  • fields (Iterable[str]) – list of fields names from the vector layer to show. Set to an empty list to show all feature attributes.

  • refresh (bool = True) – set to True to force the table to refetch features from its vector layer and immediately update the display of the table. This may result in the table changing size to accommodate the new displayed feature attributes.

setFeatureFilter(self, expression: str)

Sets the expression used for filtering features in the table. The filter is only active if filterFeatures() is set to True. Changing this setting forces the table to refetch features from its vector layer, and may result in the table changing size to accommodate the new displayed feature attributes.

See also

featureFilter()

Parameters

expression (str) –

setFilterFeatures(self, filter: bool)

Sets whether the feature filter is active for the attribute table. Changing this setting forces the table to refetch features from its vector layer, and may result in the table changing size to accommodate the new displayed feature attributes.

See also

filterFeatures()

Parameters

filter (bool) –

setFilterToAtlasFeature(self, filterToAtlas: bool)

Sets attribute table to only show features which intersect the current atlas feature.

Parameters

filterToAtlas (bool) –

setMap(self, map: QgsLayoutItemMap)

Sets a layout map to use to limit the extent of features shown in the attribute table. This setting only has an effect if setDisplayOnlyVisibleFeatures is set to True. Changing the map forces the table to refetch features from its vector layer, and may result in the table changing size to accommodate the new displayed feature attributes.

See also

map()

Parameters

map (QgsLayoutItemMap) –

setMaximumNumberOfFeatures(self, features: int)

Sets the maximum number of features shown by the table. Changing this setting may result in the attribute table changing its size to accommodate the new number of rows, and requires the table to refetch features from its vector layer.

Parameters

features (int) –

setRelationId(self, id: str)

Sets the relation id from which to display child features

See also

relationId()

See also

setSource()

Note

Only used if table source() is set to RelationChildren.

Parameters

id (str) –

setSource(self, source: QgsLayoutItemAttributeTable.ContentSource)

Sets the source for attributes to show in table body.

See also

source()

Parameters

source (QgsLayoutItemAttributeTable.ContentSource) –

setUniqueRowsOnly(self, uniqueOnly: bool)

Sets attribute table to only show unique rows.

Set uniqueOnly to True to show only unique rows. Duplicate rows will be stripped from the table.

See also

uniqueRowsOnly()

Parameters

uniqueOnly (bool) –

setVectorLayer(self, layer: QgsVectorLayer)

Sets the vector layer from which to display feature attributes.

This is only considered if the table source() is LayerAttributes.

vectorLayer()

Parameters

layer (QgsVectorLayer) –

setWrapString(self, wrapString: str)

Sets a string to wrap the contents of the table cells by. Occurrences of this string will be replaced by a line break.

Parameters

wrapString (str) – string to replace with line break

source(self) → QgsLayoutItemAttributeTable.ContentSource

Returns the source for attributes shown in the table body.

setSource()

Return type

QgsLayoutItemAttributeTable.ContentSource

sourceLayer(self) → QgsVectorLayer

Returns the source layer for the table, considering the table source mode. For example, if the table is set to atlas feature mode, then the source layer will be the atlas coverage layer. If the table is set to layer attributes mode, then the source layer will be the user specified vector layer.

Return type

QgsVectorLayer
