Public Types
enum	SelectionMode { NoSelection = 0 , SelectionX = 1 << 0 , SelectionY = 1 << 1 }
	Bitflag enumeration for defining the set of allowed/supported selections. More...

Public Slots
void	setPlotSelection (vec2 rangeX, vec2 rangeY)

Signals
void	selectionChanged (vec2 rangeX, vec2 rangeY)

Public Member Functions
	InteractionPlotView (PlotView &pv)
Flags< SelectionMode >	selectionMode () const
	Returns the set of supported selection modes.
void	setSelectionMode (Flags< SelectionMode > value)
	Sets the set of supported selection modes.
bool	sceneEvent (QEvent *event) override
	Modify the translation and rotation parameters based on the mouse events.
void	contextMenuCreate (QMenu &m) override
	Create context menu entries.
void	contextMenuEvaluate (QAction *a) override
	Evaluate action chosen in context menu.
void	createActions () override
	Create context menu actions.
void	updateSpectrum ()
void	setSpectrumVisible (bool on)
Public Member Functions inherited from ViewInteraction
	ViewInteraction (InteractiveView &view)
	Instantiate a new ViewInteraction that contains already basic actions for the view.
void	contextMenuCreate (QMenu &m) override
	Create context menu entries.
virtual void	setViewActionMap (ViewActionMap *m)
	Sets the action mapping of this view. If nullptr, will default to the global one.
virtual ViewActionMap *	viewActionMap ()
	Returns the local view action map for this view interaction, if any has been set.
void	setMouseActionSpeed (ViewActionType action, double speed)
	Setters for the speed of a mouse (touch) action.
void	setTouchActionSpeed (ViewActionType action, double speed)
double	mouseActionSpeed (ViewActionType action) const
	Getters for the speed of a mouse (touch) action, return the default value if the action is not found in the map.
double	touchActionSpeed (ViewActionType action) const
bool	matchMappedActions (ViewActionType viewAction, Qt::MouseButton button, Qt::KeyboardModifiers modifiers) const
	Returns true if the MouseAction defined by button and modifiers is registered for the viewAction.
virtual void	createCustomViewActionMap ()
	Must be used to override the global view action mapper This method can be overridden in order to define a custom default mapping between view actions and user mouse events Example code for the overridden method:
Public Member Functions inherited from Interaction
virtual void	openContextMenu (QPoint pos, QPoint globalPos, Qt::KeyboardModifiers modifiers)
virtual void	reset ()
void	setUseContextMenu (bool use)
	Set if the context menu must be created or not.
bool	useContextMenu () const
	Specifies if the view creates context menu entries or not. Default value is false.

	Loads the default view interaction mapping.
static const ViewActionMap &	globalViewActionMap ()
	Const access to the global view action mapper.
