bool QgsLayoutItemAttributeTable::displayOnlyVisibleFeatures ( ) const

inline

Returns true if the table is set to show only features visible on a corresponding map item.

See also: map(); setDisplayOnlyVisibleFeatures()

Definition at line 194 of file qgslayoutitemattributetable.h.

◆ featureFilter()

QString QgsLayoutItemAttributeTable::featureFilter ( ) const

inline

Returns the current expression used to filter features for the table.

◆ finalizeRestoreFromXml()

void QgsLayoutItemAttributeTable::finalizeRestoreFromXml ( )

overridevirtual

Called after all pending items have been restored from XML.

Multiframes can use this method to run steps which must take place after all items have been restored to the layout, such as connecting to signals emitted by other items, which may not have existed in the layout at the time readXml() was called. E.g. a scalebar can use this to connect to its linked map item after restoration from XML.

See also: readXml()

Reimplemented from QgsLayoutMultiFrame.

Definition at line 648 of file qgslayoutitemattributetable.cpp.

◆ getTableContents()

bool QgsLayoutItemAttributeTable::getTableContents ( QgsLayoutTableContents & contents )

overridevirtual

Queries the attribute table's vector layer for attributes to show in the table.

Parameters

contents table content

Returns: true if attributes were successfully fetched

Note: not available in Python bindings

Definition at line 144 of file qgslayoutitemattributetable.h.

◆ maximumNumberOfFeatures()

int QgsLayoutItemAttributeTable::maximumNumberOfFeatures ( ) const

inline

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

See also: setMaximumNumberOfFeatures()

Definition at line 158 of file qgslayoutitemattributetable.h.

◆ readPropertiesFromElement()

bool QgsLayoutItemAttributeTable::readPropertiesFromElement	(	const QDomElement &	element,
		const QDomDocument &	document,
		const QgsReadWriteContext &	context
	)

overrideprotectedvirtual

Sets multiframe state from a DOM element.

Parameters

element	is the DOM element for the multiframe
document	DOM document
context	read write context

See also: writePropertiesToElement()

Note that item subclasses should not rely on all other items being present in the layout at the time this method is called. Instead, any connections and links to other items must be made in the finalizeRestoreFromXml() method. E.g. when restoring a scalebar, the connection to the linked map's signals should be implemented in finalizeRestoreFromXml(), not readPropertiesFromElement().

See also: readXml()

◆ setDisplayOnlyVisibleFeatures()

void QgsLayoutItemAttributeTable::setDisplayOnlyVisibleFeatures ( bool visibleOnly )

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: displayOnlyVisibleFeatures(); setMap()

Definition at line 265 of file qgslayoutitemattributetable.cpp.

◆ setFeatureFilter()

void QgsLayoutItemAttributeTable::setFeatureFilter ( const QString & expression )

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(); setFilterFeatures()

Definition at line 301 of file qgslayoutitemattributetable.cpp.

◆ setFilterFeatures()

void QgsLayoutItemAttributeTable::setFilterFeatures ( bool filter )

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(); setFeatureFilter()

Definition at line 289 of file qgslayoutitemattributetable.cpp.

◆ setFilterToAtlasFeature()

void QgsLayoutItemAttributeTable::setFilterToAtlasFeature ( bool filterToAtlas )

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

See also: filterToAtlasFeature()

Definition at line 277 of file qgslayoutitemattributetable.cpp.

◆ setMap()

void QgsLayoutItemAttributeTable::setMap ( QgsLayoutItemMap * map )

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(); setDisplayOnlyVisibleFeatures

Definition at line 220 of file qgslayoutitemattributetable.cpp.

◆ setMaximumNumberOfFeatures()

void QgsLayoutItemAttributeTable::setMaximumNumberOfFeatures ( int features )

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.

See also: maximumNumberOfFeatures()

Definition at line 241 of file qgslayoutitemattributetable.cpp.

◆ setRelationId()

void QgsLayoutItemAttributeTable::setRelationId ( const QString & id )
