A QgsMapMouseEvent is the result of a user interaction with the mouse on a QgsMapCanvas.
The QgsMapToolIdentifyFeature class is a map tool to identify a feature on a chosen layer.
void featureIdentified(const QgsFeature &)
void setLayer(QgsVectorLayer *vl)
change the layer used by the map tool to identify
void featureIdentified(QgsFeatureId)
Map tool for identifying features in layers.
void canvasReleaseEvent(QgsMapMouseEvent *e) override
Mouse release event for overriding. Default implementation does nothing.
virtual void keyPressEvent(QKeyEvent *e)
Key event for overriding. Default implementation does nothing.
Definition: qgsmaptool.cpp:193
Represents a vector layer which manages a vector based data sets.
qint64 QgsFeatureId
64 bit feature ids negative numbers are used for uncommitted/newly added features
