	)

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()

Reimplemented from QgsLayoutMultiFrame.

Definition at line 913 of file qgslayoutitemattributetable.cpp.

Reimplemented from QgsLayoutTable.

Definition at line 708 of file qgslayoutitemattributetable.cpp.

◆ setDisplayedFields()

void QgsLayoutItemAttributeTable::setDisplayedFields	(	const QStringList &	fields,
		bool	refresh = `true`
	)

Sets the attributes to display in the table.

Parameters

fields	list of fields names from the vector layer to show. Set to an empty list to show all feature attributes.
refresh	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.

Definition at line 319 of file qgslayoutitemattributetable.cpp.

◆ 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 271 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 307 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 295 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 283 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 227 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 247 of file qgslayoutitemattributetable.cpp.

◆ setRelationId()

void QgsLayoutItemAttributeTable::setRelationId ( const QString & id )

Sets the relation id from which to display child features.

See also: relationId(); setSource()

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

Definition at line 108 of file qgslayoutitemattributetable.cpp.

◆ setSource()

void QgsLayoutItemAttributeTable::setSource ( const QgsLayoutItemAttributeTable::ContentSource source )

Sets the source for attributes to show in table body.

See also: source()

Definition at line 969 of file qgslayoutitemattributetable.cpp.

◆ setUniqueRowsOnly()

void QgsLayoutItemAttributeTable::setUniqueRowsOnly ( bool uniqueOnly )

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()

Definition at line 259 of file qgslayoutitemattributetable.cpp.

◆ setUseConditionalStyling()

void QgsLayoutItemAttributeTable::setUseConditionalStyling ( bool enabled )

Sets whether the attribute table will be rendered using the conditional styling properties of the linked vector layer.

See also: useConditionalStyling()

Since: QGIS 3.12

Definition at line 215 of file qgslayoutitemattributetable.cpp.

◆ setVectorLayer()

void QgsLayoutItemAttributeTable::setVectorLayer ( QgsVectorLayer * layer )

Sets the vector layer from which to display feature attributes.

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

See also: vectorLayer()

Definition at line 78 of file qgslayoutitemattributetable.cpp.

◆ setWrapString()

void QgsLayoutItemAttributeTable::setWrapString ( const QString & wrapString )

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 string to replace with line break

See also: wrapString()

Definition at line 870 of file qgslayoutitemattributetable.cpp.

◆ source()

ContentSource QgsLayoutItemAttributeTable::source ( ) const

Definition at line 75 of file qgslayoutitemattributetable.h.

◆ sourceLayer()

QgsVectorLayer * QgsLayoutItemAttributeTable::sourceLayer ( ) const

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.

Definition at line 835 of file qgslayoutitemattributetable.cpp.

◆ textFormatForCell()

QgsTextFormat QgsLayoutItemAttributeTable::textFormatForCell	(	int	row,
		int	column

int QgsLayoutItemAttributeTable::type ( ) const

overridevirtual

Returns unique multiframe type id.

Implements QgsLayoutMultiFrame.

Definition at line 58 of file qgslayoutitemattributetable.cpp.

◆ uniqueRowsOnly()

bool QgsLayoutItemAttributeTable::uniqueRowsOnly ( ) const

inline

Returns true if the table is set to show only unique rows.

◆ wrapString()

QString QgsLayoutItemAttributeTable::wrapString ( ) const

inline

Returns the string used to wrap the contents of the table cells by.

Occurrences of this string will be replaced by a line break.

See also: setWrapString()
