Constructor & Destructor Documentation

◆ QgsTrackedVectorLayerTools()

QgsTrackedVectorLayerTools::QgsTrackedVectorLayerTools ( )
default

Constructor for QgsTrackedVectorLayerTools.

Member Function Documentation

◆ addFeature()

bool QgsTrackedVectorLayerTools::addFeature ( QgsVectorLayer layer,
const QgsAttributeMap defaultValues,
const QgsGeometry defaultGeometry,
QgsFeature feature 
) const
overridevirtual

This method should/will be called, whenever a new feature will be added to the layer.

Parameters
layerThe layer to which the feature should be added
defaultValuesDefault values for the feature to add
defaultGeometryA default geometry to add to the feature
featureUpdated feature after adding will be written back to this
Returns
true in case of success, false if the operation failed/was aborted

Implements QgsVectorLayerTools.

Definition at line 20 of file qgstrackedvectorlayertools.cpp.

◆ copyMoveFeatures()

bool QgsTrackedVectorLayerTools::copyMoveFeatures ( QgsVectorLayer layer,
QgsFeatureRequest request,
double  dx = 0,
double  dy = 0,
QString *  errorMsg = nullptr,
const bool  topologicalEditing = false,
QgsVectorLayer topologicalLayer = nullptr 
) const
overridevirtual

Copy and move features with defined translation.

Parameters
layerThe layer
requestThe request for the features to be moved. It will be assigned to a new feature request with the newly copied features.
dxThe translation on x
dyThe translation on y
errorMsgIf given, it will contain the error message
topologicalEditingIf true, the function will perform topological editing of the vertices of layer on layer and topologicalLayer
topologicalLayerThe layer where vertices from the moved features of layer will be added
Returns
true if all features could be copied.

Reimplemented from QgsVectorLayerTools.

Definition at line 56 of file qgstrackedvectorlayertools.cpp.

◆ rollback()

void QgsTrackedVectorLayerTools::rollback ( )

Delete all features which have been added via this object.

Definition at line 66 of file qgstrackedvectorlayertools.cpp.

◆ saveEdits()

bool QgsTrackedVectorLayerTools::saveEdits ( QgsVectorLayer layer) const
overridevirtual

Should be called, when the features should be committed but the editing session is not ended.

Parameters
layerThe layer to commit
Returns
true if successful

Implements QgsVectorLayerTools.

Definition at line 51 of file qgstrackedvectorlayertools.cpp.

◆ setVectorLayerTools()

void QgsTrackedVectorLayerTools::setVectorLayerTools ( const QgsVectorLayerTools tools)

Set the vector layer tools that will be used to interact with the data.

Definition at line 61 of file qgstrackedvectorlayertools.cpp.

◆ startEditing()

bool QgsTrackedVectorLayerTools::startEditing ( QgsVectorLayer layer) const
overridevirtual

This will be called, whenever a vector layer should be switched to edit mode.

Check the providers capability to edit in here. If successful layer->startEditing() will be called and true returned.

Parameters
layerThe layer on which to start an edit session
Returns
true, if the editing session was started

Implements QgsVectorLayerTools.

Definition at line 41 of file qgstrackedvectorlayertools.cpp.

◆ stopEditing()

bool QgsTrackedVectorLayerTools::stopEditing ( QgsVectorLayer layer,
bool  allowCancel 
) const
overridevirtual

Will be called, when an editing session is ended and the features should be committed.

Appropriate dialogs should be shown like

Parameters
layerThe layer to commit
allowCanceltrue if a cancel button should be offered
Returns
true if successful

Implements QgsVectorLayerTools.
