Specifies the content source for the attribute table.

Enumerator

int  column 
) const
overridevirtual

Returns the conditional style to use for the cell at row, column.

Since
QGIS 3.12

Reimplemented from QgsLayoutTable.

Definition at line 664 of file qgslayoutitemattributetable.cpp.

◆ create()

QgsLayoutItemAttributeTable * QgsLayoutItemAttributeTable::create ( QgsLayout layout)
static

Returns a new QgsLayoutItemAttributeTable for the specified parent layout.

Definition at line 101 of file qgslayoutitemattributetable.cpp.

◆ createExpressionContext()

QgsExpressionContext QgsLayoutItemAttributeTable::createExpressionContext ( ) const
overridevirtual

This method needs to be reimplemented in all classes which implement this interface and return an expression context.

Since
QGIS 3.0

Implements QgsExpressionContextGenerator.

Definition at line 672 of file qgslayoutitemattributetable.cpp.

◆ displayName()

QString QgsLayoutItemAttributeTable::displayName ( ) const
overridevirtual

Returns the multiframe display name.

Reimplemented from QgsLayoutMultiFrame.

Definition at line 106 of file qgslayoutitemattributetable.cpp.

◆ displayOnlyVisibleFeatures()

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.

The filter is only active if filterFeatures() is true.

See also
setFeatureFilter()
filterFeatures()

Definition at line 236 of file qgslayoutitemattributetable.h.

◆ filterFeatures()

bool QgsLayoutItemAttributeTable::filterFeatures ( ) const
inline

See also
setFilterFeatures()
featureFilter()

Definition at line 218 of file qgslayoutitemattributetable.h.

◆ filterToAtlasFeature()

bool QgsLayoutItemAttributeTable::filterToAtlasFeature ( ) const
inline

See also
setFilterToAtlasFeature()

Definition at line 210 of file qgslayoutitemattributetable.h.

◆ 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 684 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
contentstable content
Returns
true if attributes were successfully fetched
Note
not available in Python bindings

Implements QgsLayoutTable.

Definition at line 424 of file qgslayoutitemattributetable.cpp.

◆ icon()

QIcon QgsLayoutItemAttributeTable::icon ( ) const
overridevirtual

Returns the item's icon.

Reimplemented from QgsLayoutMultiFrame.

Definition at line 96 of file qgslayoutitemattributetable.cpp.

◆ map()

QgsLayoutItemMap* QgsLayoutItemAttributeTable::map ( ) const
inline

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.

See also
setMap()
displayOnlyVisibleFeatures()

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
elementis the DOM element for the multiframe
documentDOM document
contextread 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 844 of file qgslayoutitemattributetable.cpp.

◆ refreshDataDefinedProperty()

void QgsLayoutItemAttributeTable::refreshDataDefinedProperty ( QgsLayoutObject::DataDefinedProperty  property = QgsLayoutObject::AllProperties)
overridevirtual

Refreshes a data defined property for the multi frame by reevaluating the property's value and redrawing the item with this new value.

If property is set to QgsLayoutObject::AllProperties then all data defined properties for the item will be refreshed.

Reimplemented from QgsLayoutMultiFrame.

Sets the attributes to display in the table.

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

◆ 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.

◆ setFeatureFilter()

void QgsLayoutItemAttributeTable::setFeatureFilter ( const QString &  expression)

Sets the expression used for filtering features in the table.

setFilterFeatures()

Definition at line 340 of file qgslayoutitemattributetable.cpp.

◆ setFilterFeatures()

void QgsLayoutItemAttributeTable::setFilterFeatures ( bool  filter)

Sets whether the feature filter is active for the attribute table.

◆ 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.

map()
setDisplayOnlyVisibleFeatures

Definition at line 259 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 280 of file qgslayoutitemattributetable.cpp.

◆ setRelationId()

void QgsLayoutItemAttributeTable::setRelationId ( const QString &  id)

Sets the relation id from which to display child features.

◆ 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.

◆ sortAttributes()

QVector< QPair< int, bool > > QgsLayoutItemAttributeTable::sortAttributes ( ) const

Returns the attributes used to sort the table's features.

Returns
a QList of integer/bool pairs, where the integer refers to the attribute index and the bool to the sort order for the attribute. If true the attribute is sorted ascending, if false, the attribute is sorted in descending order.

◆ 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.
