void deactivate() override
Unregisters this maptool from the cad dock widget.
QFlags< Capability > Capabilities
void keyPressEvent(QKeyEvent *e) override
Intercept key events like Esc or Del to delete the last point.
void activate() override
Registers this maptool with the cad dock widget.
CaptureMode
Different capture modes.
@ CaptureNone
Do not capture / determine mode from layer geometry type.
virtual bool supportsTechnique(Qgis::CaptureTechnique technique) const
Returns true if the tool supports the specified capture technique.
virtual QgsMapToolCapture::Capabilities capabilities() const
Returns flags containing the supported capabilities.
void cadCanvasReleaseEvent(QgsMapMouseEvent *e) override
Override this method when subclassing this class.

void digitizingCanceled()
Emitted when the digitizing process was interrupted by the user.
void digitizingCompleted(const QgsFeature &feature)
Emitted whenever the digitizing has been successfully completed.
void digitizingFinished()
Emitted whenever the digitizing has been ended without digitizing any feature.
virtual void reactivate()
Called when the map tool is being activated while it is already active.
