Class: QgsMapToolEmitPoint

class qgis.gui.QgsMapToolEmitPoint(canvas: QgsMapCanvas)

Bases: QgsMapTool

constructor

A map tool that simply emits a point when clicking on the map. Connecting a slot to its canvasClicked() signal will let you implement custom behavior for the passed in point.

Parameters

canvas

canvasClicked

signal emitted on canvas click [signal]

Parameters
  • point (QgsPointXY) –

  • button (Qt.MouseButton) –

canvasMoveEvent(self, e: QgsMapMouseEvent)
Parameters

e (QgsMapMouseEvent) –

canvasPressEvent(self, e: QgsMapMouseEvent)
Parameters

e (QgsMapMouseEvent) –

canvasReleaseEvent(self, e: QgsMapMouseEvent)
Parameters

e (QgsMapMouseEvent) –

childEvent(self, QChildEvent)
connectNotify(self, QMetaMethod)
customEvent(self, QEvent)
disconnectNotify(self, QMetaMethod)
flags(self)QgsMapTool.Flags
Return type

QgsMapTool.Flags

isSignalConnected(self, QMetaMethod) → bool
receivers(self, PYQT_SIGNAL) → int
sender(self) → QObject
senderSignalIndex(self) → int
timerEvent(self, QTimerEvent)
toCanvasCoordinates(self, point: QgsPointXY) → QPoint

transformation from map coordinates to screen coordinates

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

transformation from screen coordinates to layer’s coordinates

toLayerCoordinates(self, layer: QgsMapLayer, point: QgsPointXY) -> QgsPointXY transformation from map coordinates to layer’s coordinates

toLayerCoordinates(self, layer: QgsMapLayer, rect: QgsRectangle) -> QgsRectangle trnasformation of the rect from map coordinates to layer’s coordinates

toMapCoordinates(self, point: QPoint)QgsPointXY

transformation from screen coordinates to map coordinates

toMapCoordinates(self, layer: QgsMapLayer, point: QgsPointXY) -> QgsPointXY transformation from layer’s coordinates to map coordinates (which is different in case reprojection is used)

toMapCoordinatesV2(self, layer: QgsMapLayer, point: QgsPoint)QgsPoint

transformation from layer’s coordinates to map coordinates (which is different in case reprojection is used)

Note

available in Python bindings as toMapCoordinatesV2
