QgsMapToolIdentifyFeature is a map tool to identify a feature on a chosen layer

Parameters:

• canvas (Optional[QgsMapCanvas]) – the map canvas

• vl (Optional[QgsVectorLayer] = None) – the vector layer. The map tool can be initialized without any layer and can be set afterward.

signal featureIdentified

pyqtSignal(*types, name: str = …, revision: int = …, arguments: Sequence = …) -> PYQT_SIGNAL

types is normally a sequence of individual types. Each type is either a type object or a string that is the name of a C++ type. Alternatively each type could itself be a sequence of types each describing a different overloaded signal. name is the optional C++ name of the signal. If it is not specified then the name of the class attribute that is bound to the signal is used. revision is the optional revision of the signal that is exported to QML. If it is not specified then 0 is used. arguments is the optional sequence of the names of the signal’s arguments.

setLayer(self, vl: QgsVectorLayer | None)

change the layer used by the map tool to identify

Parameters:

vl (Optional[QgsVectorLayer])
