Return type

QgsMapTool.Flags

gestureEvent(self, e: QGestureEvent) bool
Parameters

e (QGestureEvent) –

Return type

bool

isDragging(self) bool

Returns True if a drag operation is in progress.

New in version 3.12.

Return type

bool

isSignalConnected(self, QMetaMethod) bool
layer(self, id: str) QgsMapLayer

Returns the map layer with the matching ID, or None if no layers could be found.

This method searches both layers associated with the map canvas (see QgsMapCanvas.layers()) and layers from the QgsProject associated with the canvas. It can be used to resolve layer IDs to layers which may be visible in the canvas, but not associated with a QgsProject.

New in version 3.22.

panDistanceBearingChanged

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.

Parameters
  • name (str = ...) –

  • revision (int = ...) –

  • arguments (Sequence = ...) –

Return type

PYQT_SIGNAL

receivers(self, PYQT_SIGNAL) int
sender(self) QObject
senderSignalIndex(self) int
setToolName(self, name: str)

Sets the tool’s name.

toLayerCoordinates(self, layer: QgsMapLayer, point: QPoint) QgsPointXY

Transforms a point from screen coordinates to layer coordinates.

toLayerCoordinates(self, layer: QgsMapLayer, point: QgsPointXY) -> QgsPointXY Transforms a point from map coordinates to layer coordinates.

toLayerCoordinates(self, layer: QgsMapLayer, rect: QgsRectangle) -> QgsRectangle Transforms a rect from map coordinates to layer coordinates.
