childEvent(self, a0: QChildEvent | None)

connectNotify(self, signal: QMetaMethod)

constrainPointToRect(point: QPointF | QPoint, rect: QRectF) → QPointF

Constrains a point to force it to fall within the specified rectangle.

customEvent(self, a0: QEvent | None)

deactivate(self)

disconnectNotify(self, signal: QMetaMethod)

isClickAndDrag(self, startViewPoint: QPoint, endViewPoint: QPoint) → bool

Returns True if a mouse press/release operation which started at startViewPoint and ended at endViewPoint should be considered a “click and drag”. If False is returned, the operation should be instead treated as just a click on startViewPoint.

isSignalConnected(self, signal: QMetaMethod) → bool

keyPressEvent(self, event: QKeyEvent | None)

Parameters:

event (Optional[QKeyEvent])

keyReleaseEvent(self, event: QKeyEvent | None)

Parameters:

event (Optional[QKeyEvent])

plotMoveEvent(self, event: QgsPlotMouseEvent | None)

Parameters:

event (Optional[QgsPlotMouseEvent])

plotPressEvent(self, event: QgsPlotMouseEvent | None)

Parameters:

event (Optional[QgsPlotMouseEvent])

plotReleaseEvent(self, event: QgsPlotMouseEvent | None)

Parameters:

event (Optional[QgsPlotMouseEvent])

receivers(self, signal: PYQT_SIGNAL) → int

sender(self) → QObject | None

senderSignalIndex(self) → int

timerEvent(self, a0: QTimerEvent | None)

toCanvasCoordinates(self, point: QgsPoint) → QgsPointXY

Converts a point in map coordinates to the associated canvas point.

May return an empty point if the map point cannot be converted to a canvas point.

toMapCoordinates(self, point: QgsPointXY) → QgsPoint

Converts a point on the canvas to the associated map coordinate.

May return an empty point if the canvas point cannot be converted to a map point.
