Detailed Description

an abstract superclass for classes observing events invoked by vtkRenderWindowInteractor

vtkInteractorObserver is an abstract superclass for subclasses that observe events invoked by vtkRenderWindowInteractor. These subclasses are typically things like 3D widgets; objects that interact with actors in the scene, or interactively probe the scene for information.

vtkInteractorObserver defines the method SetInteractor() and enables and disables the processing of events by the vtkInteractorObserver. Use the methods EnabledOn() or SetEnabled(1) to turn on the interactor observer, and the methods EnabledOff() or SetEnabled(0) to turn off the interactor. Initial value is 0.

To support interactive manipulation of objects, this class (and subclasses) invoke the events StartInteractionEvent, InteractionEvent, and EndInteractionEvent. These events are invoked when the vtkInteractorObserver enters a state where rapid response is desired: mouse motion, etc. The events can be used, for example, to set the desired update frame rate (StartInteractionEvent), operate on data or update a pipeline (InteractionEvent), and set the desired frame rate back to normal values (EndInteractionEvent). Two other events, EnableEvent and DisableEvent, are invoked when the interactor observer is enabled or disabled.

virtual void vtkInteractorObserver::SetInteractor ( vtkRenderWindowInteractor iren)
virtual

This method is used to associate the widget with the render window interactor. Observers of the appropriate events invoked in the render window interactor are set up as a result of this method invocation. The SetInteractor() method must be invoked prior to enabling the vtkInteractorObserver. It automatically registers available pickers to the Picking Manager.

Reimplemented in vtkInteractorStyle, vtkSeedWidget, vtkInteractorStyleTreeMapHover, vtkGeoInteractorStyle, vtkInteractorStyleAreaSelectHover, vtkInteractorStyleSwitch, and vtkInteractorEventRecorder.

virtual vtkRenderWindowInteractor* vtkInteractorObserver::GetInteractor ( )
virtual

This method is used to associate the widget with the render window interactor. Observers of the appropriate events invoked in the render window interactor are set up as a result of this method invocation. The SetInteractor() method must be invoked prior to enabling the vtkInteractorObserver. It automatically registers available pickers to the Picking Manager.

Reimplemented in vtkInteractorStyleSwitchBase.

virtual void vtkInteractorObserver::SetPriority ( float  )
virtual

Set/Get the priority at which events are processed. This is used when multiple interactor observers are used simultaneously. The default value is 0.0 (lowest priority.) Note that when multiple interactor observer have the same priority, then the last observer added will process the event first. (Note: once the SetInteractor() method has been called, changing the priority does not effect event processing. You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)

Reimplemented in vtkAbstractWidget.

virtual float vtkInteractorObserver::GetPriority ( )
virtual

Set/Get the priority at which events are processed. This is used when multiple interactor observers are used simultaneously. The default value is 0.0 (lowest priority.) Note that when multiple interactor observer have the same priority, then the last observer added will process the event first. (Note: once the SetInteractor() method has been called, changing the priority does not effect event processing. You will have to SetInteractor(NULL), change priority, and then SetInteractor(iren) to have the priority take effect.)

virtual void vtkInteractorObserver::PickingManagedOn ( )
virtual

Enable/Disable the use of a manager to process the picking. Enabled by default.

virtual void vtkInteractorObserver::PickingManagedOff ( )
virtual

Enable/Disable the use of a manager to process the picking. Enabled by default.

virtual

Enable/Disable the use of a manager to process the picking. Enabled by default.

virtual void vtkInteractorObserver::SetKeyPressActivation ( int  )
virtual

Enable/Disable of the use of a keypress to turn on and off the interactor observer. (By default, the keypress is 'i' for "interactor observer".) Set the KeyPressActivationValue to change which key activates the widget.)

virtual int vtkInteractorObserver::GetKeyPressActivation ( )
virtual

Enable/Disable of the use of a keypress to turn on and off the interactor observer. (By default, the keypress is 'i' for "interactor observer".) Set the KeyPressActivationValue to change which key activates the widget.)

virtual void vtkInteractorObserver::KeyPressActivationOn ( )
virtual

Enable/Disable of the use of a keypress to turn on and off the interactor observer. (By default, the keypress is 'i' for "interactor observer".) Set the KeyPressActivationValue to change which key activates the widget.)

virtual void vtkInteractorObserver::KeyPressActivationOff ( )
virtual

Enable/Disable of the use of a keypress to turn on and off the interactor observer. (By default, the keypress is 'i' for "interactor observer".) Set the KeyPressActivationValue to change which key activates the widget.)

virtual void vtkInteractorObserver::SetKeyPressActivationValue ( char  )
virtual

Specify which key press value to use to activate the interactor observer (if key press activation is enabled). By default, the key press activation value is 'i'. Note: once the SetInteractor() method is invoked, changing the key press activation value will not affect the key press until SetInteractor(NULL)/SetInteractor(iren) is called.

virtual char vtkInteractorObserver::GetKeyPressActivationValue ( )
virtual

Specify which key press value to use to activate the interactor observer (if key press activation is enabled). By default, the key press activation value is 'i'. Note: once the SetInteractor() method is invoked, changing the key press activation value will not affect the key press until SetInteractor(NULL)/SetInteractor(iren) is called.

virtual vtkRenderer* vtkInteractorObserver::GetDefaultRenderer ( )
virtual

Set/Get the default renderer to use when activating the interactor observer. Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used. Alternatively, you can specify the renderer to bind the interactor to when the interactor observer is activated.

virtual void vtkInteractorObserver::SetDefaultRenderer ( vtkRenderer )
virtual

Set/Get the default renderer to use when activating the interactor observer. Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used. Alternatively, you can specify the renderer to bind the interactor to when the interactor observer is activated.

Reimplemented in vtkInteractorStyleSwitch.

virtual vtkRenderer* vtkInteractorObserver::GetCurrentRenderer ( )
virtual

Set/Get the current renderer. Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used and assigned to this Ivar. Alternatively, you might want to set the CurrentRenderer explicitly. WARNING: note that if the DefaultRenderer Ivar is set (see above), it will always override the parameter passed to SetCurrentRenderer, unless it is NULL. (i.e., SetCurrentRenderer(foo) = SetCurrentRenderer(DefaultRenderer).

virtual void vtkInteractorObserver::SetCurrentRenderer ( vtkRenderer )
virtual

Set/Get the current renderer. Normally when the widget is activated (SetEnabled(1) or when keypress activation takes place), the renderer over which the mouse pointer is positioned is used and assigned to this Ivar. Alternatively, you might want to set the CurrentRenderer explicitly. WARNING: note that if the DefaultRenderer Ivar is set (see above), it will always override the parameter passed to SetCurrentRenderer, unless it is NULL. (i.e., SetCurrentRenderer(foo) = SetCurrentRenderer(DefaultRenderer).

void vtkInteractorObserver::GrabFocus ( vtkCommand mouseEvents,
vtkCommand keypressEvents = NULL 
)

These methods enable an interactor observer to exclusively grab all events invoked by its associated vtkRenderWindowInteractor. (This method is typically used by widgets to grab events once an event sequence begins.) The GrabFocus() signature takes up to two vtkCommands corresponding to mouse events and keypress events. (These two commands are separated so that the widget can listen for its activation keypress, as well as listening for DeleteEvents, without actually having to process mouse events.)

void vtkInteractorObserver::ReleaseFocus ( )

These methods enable an interactor observer to exclusively grab all events invoked by its associated vtkRenderWindowInteractor. (This method is typically used by widgets to grab events once an event sequence begins.) The GrabFocus() signature takes up to two vtkCommands corresponding to mouse events and keypress events. (These two commands are separated so that the widget can listen for its activation keypress, as well as listening for DeleteEvents, without actually having to process mouse events.)
