const QString &  newName 
)
signal

Emitted when an attribute has been renamed.

idxattribute index
newNamenew attribute name

const QVariant &   
)
signal

const QVariant &  newValue,
const QVariant &  oldValue = QVariant() 
)
virtual

Changed an attribute value (but does not commit it)

Reimplemented in QgsVectorLayerEditPassthrough.

Definition at line 232 of file qgsvectorlayereditbuffer.cpp.

◆ changeAttributeValues()

bool QgsVectorLayerEditBuffer::changeAttributeValues ( QgsFeatureId  fid,
const QgsAttributeMap newValues,
const QgsAttributeMap oldValues 
)
virtual

Changes values of attributes (but does not commit it).

Reimplemented in QgsVectorLayerEditPassthrough.

Definition at line 214 of file qgsvectorlayereditbuffer.cpp.

◆ changedAttributeValues()

QgsChangedAttributesMap QgsVectorLayerEditBuffer::changedAttributeValues ( ) const
inline

Returns a map of features with changed attributes values which are not committed.

See also
isFeatureAttributesChanged()

Definition at line 129 of file qgsvectorlayereditbuffer.h.

Definition at line 193 of file qgsvectorlayereditbuffer.cpp.

◆ commitChanges()

bool QgsVectorLayerEditBuffer::commitChanges ( QStringList &  commitErrors)
virtual

Attempts to commit any changes to disk.

Returns the result of the attempt. If a commit fails, the in-memory changes are left alone.

This allows editing to continue if the commit failed on e.g. a disallowed value in a Postgres database - the user can re-edit and try again.

The commits occur in distinct stages, (add attributes, add features, change attribute values, change geometries, delete features, delete attributes) so if a stage fails, it's difficult to roll back cleanly. Therefore any error message also includes which stage failed so that the user has some chance of repairing the damage cleanly.

Reimplemented in QgsVectorLayerEditPassthrough.
