    QObject * parent=nullptr
) 

---

function appendFeatures

void MultiFeatureListModelBase::appendFeatures (
    const QList< IdentifyTool::IdentifyResult > & results
) 

Appends features from a list of results.

---

function canDeleteSelection

bool MultiFeatureListModelBase::canDeleteSelection () const

---

function canDuplicateSelection

bool MultiFeatureListModelBase::canDuplicateSelection () const

---

function canEditAttributesSelection

bool MultiFeatureListModelBase::canEditAttributesSelection () const

---

function canMergeSelection

bool MultiFeatureListModelBase::canMergeSelection () const

---

function canMoveSelection

bool MultiFeatureListModelBase::canMoveSelection () const

---

function canProcessSelection

bool MultiFeatureListModelBase::canProcessSelection () const

---

function canRotateSelection

bool MultiFeatureListModelBase::canRotateSelection () const

---

function clear

void MultiFeatureListModelBase::clear (
    const bool keepSelected=false
) 

Resets the model to either an empty feature list or one that contains only the selected features.

Parameters:

• keepSelected if set to TRUE, selected features will be kept when resetting the model.

---

function clearSelection

void MultiFeatureListModelBase::clearSelection () 

Empties the list of selected features.

---

function columnCount

int MultiFeatureListModelBase::columnCount (
    const QModelIndex & parent
) override const

---

function count

int MultiFeatureListModelBase::count () const

---

function data

QVariant MultiFeatureListModelBase::data (
    const QModelIndex & index,
    int role
) override const

---

function deleteFeature

bool MultiFeatureListModelBase::deleteFeature (
    QgsVectorLayer * layer,
    QgsFeatureId fid,
    bool selectionAction=false
) 

Deletes a feature from a vector layer

Parameters:

• layer The layer from which a feature will be removed
• fid The id of the feature to remove
• selectionAction

---

function deleteSelection

Deletes selected features.

bool MultiFeatureListModelBase::deleteSelection () 

---

function duplicateFeature

bool MultiFeatureListModelBase::duplicateFeature (
    QgsVectorLayer * layer,
    const QgsFeature & feature
) 

Duplicates a feature on a given layer

Parameters:

• layer The layer within which the feature will be duplicated
• feature The feature to be duplicated

---

function duplicateSelection

Duplicates selected features onto their associated layer.

bool MultiFeatureListModelBase::duplicateSelection () 

---

function index

QModelIndex MultiFeatureListModelBase::index (
    int row,
    int column,
    const QModelIndex & parent=QModelIndex()
) override const

---

function mergeSelection

bool MultiFeatureListModelBase::mergeSelection () 

Merges selected features by updating the first seleted feature's geometry to a combination (i.e. union) of geometries of all selected features.

All but the first feature will then be removed from the vector layer containing the selected features.

---

function moveSelection

bool MultiFeatureListModelBase::moveSelection (
    const double x,
    const double y,
    const QgsPoint & destinationPoint
) 

Moves selected feature(s) geometry by x and y. For a single feature with a singlepart point geometry containing Z and/or M values will adopt non-null values from the destinationPoint.

---

function parent

QModelIndex MultiFeatureListModelBase::parent (
    const QModelIndex & child
) override const

---

function removeRows

virtual bool MultiFeatureListModelBase::removeRows (
    int row,
    int count,
    const QModelIndex & parent
) override

Removes a defined number of rows starting from a given position. The parent index is not used as we have a list only.

Parameters:

• row The first row to remove
• count The numbe rof rows to remove
• parent Can savely be omitted as it is unused and defaults to an invalid index

---

function roleNames

QHash< int, QByteArray > MultiFeatureListModelBase::roleNames () override const

---

function rotateSelection

Rotate selected features along a given vector .

bool MultiFeatureListModelBase::rotateSelection (
    const double angle
) 

---

function rowCount

int MultiFeatureListModelBase::rowCount (
    const QModelIndex & parent
) override const

---

function selectedCount

int MultiFeatureListModelBase::selectedCount () const

---

function selectedFeatures

QList< QgsFeature > MultiFeatureListModelBase::selectedFeatures () const

---

function selectedLayer

QgsVectorLayer * MultiFeatureListModelBase::selectedLayer () const

---

function setFeatures

void MultiFeatureListModelBase::setFeatures (
    const QMap< QgsVectorLayer *, QgsFeatureRequest > & requests
) 

Resets the model to contain features found from a list of requests.

---

function toggleSelectedItem

void MultiFeatureListModelBase::toggleSelectedItem (
    int item
) 

Toggles the selection state of a given item.

Parameters:

• item the item's row number
