Public Member Functions
	DigitizeStateAbstractBase (DigitizeStateContext &context)
	Single constructor.

virtual QString	activeCurve () const =0
	Name of the active Curve. This can include AXIS_CURVE_NAME.

virtual void	begin (CmdMediator *cmdMediator, DigitizeState previousState)=0
	Method that is called at the exact moment a state is entered.

DigitizeStateContext &	context ()
	Reference to the DigitizeStateContext that contains all the DigitizeStateAbstractBase subclasses, without const.

const DigitizeStateContext &	context () const
	Reference to the DigitizeStateContext that contains all the DigitizeStateAbstractBase subclasses, without const.

virtual void	end ()=0
	Method that is called at the exact moment a state is exited. Typically called just before begin for the next state.

void	handleContextMenuEvent (CmdMediator *cmdMediator, const QString &pointIdentifier)
	Handle a right click that was intercepted earlier. This is done in the superclass since it works the same in all states.

virtual void	handleCurveChange (CmdMediator *cmdMediator)=0

	Handle leave in case an override cursor is in effect from last QDialog, by resetting the override cursor.

virtual void	handleMouseMove (CmdMediator *cmdMediator, QPointF posScreen)=0
	Handle a mouse move. This is part of an experiment to see if augmenting the cursor in Point Match mode is worthwhile.

	Handle a mouse release that was intercepted earlier.

void	handleSetOverrideCursor (CmdMediator *cmdMediator, const QCursor &cursor)
	Handle the command to set the override cursor.

void	removeOverrideCursor ()
	Remove the override cursor if it is in use. This is called after a leave event, and prior to displaying a QDialog.
