RenderWindowInteractor

Source (.js)Source (.d.ts)

Introduction

vtkRenderWindowInteractor provides an interaction mechanism for mouse/key/time events. It handles routing of mouse/key/timer messages to vtkInteractorObserver and its subclasses. vtkRenderWindowInteractor also provides controls for picking, rendering frame rate.

vtkRenderWindowInteractor serves to hold user preferences and route messages to vtkInteractorStyle. Callbacks are available for many events. Platform specific subclasses should provide methods for manipulating timers, TerminateApp, and an event loop if required via

Initialize/Start/Enable/Disable.

Caveats

vtkRenderWindowInteractor routes events through VTK’s command/observer design pattern. That is, when vtkRenderWindowInteractor (actually, one of its subclasses) sees an event, it translates it into a VTK event using the InvokeEvent() method. Afterward, any vtkInteractorObservers registered for that event are expected to respond appropriately.

Methods

animationEvent

Argument	Type	Required	Description
args		Yes

button3DEvent

Triggers the 'Button3D' event.

Argument	Type	Required	Description
args		Yes

cancelAnimation

Argument	Type	Required	Description
requestor		Yes
skipWarning	Boolean	No

delete

Stop animating if the renderWindowInteractor is deleted.

disable

enable

Enable/Disable interactions. By default interactors are enabled when initialized. Initialize() must be called prior to enabling/disabling interaction. These methods are used when a window/widget is being shared by multiple renderers and interactors. This allows a "modal" display where one interactor is active when its data is to be displayed and all other interactors associated with the widget are disabled when their data is not displayed.

Argument	Type	Required	Description
args		Yes

recognizeGesture

we know we are in multitouch now, so start recognizing

Argument	Type	Required	Description
event		Yes
positions		Yes

render

only render if we are not animating. If we are animating then renders will happen naturally anyhow and we definitely do not want extra renders as the make the apparent interaction rate slower.

args		Yes

rightButtonReleaseEvent

Argument	Type	Required	Description

Argument	Type	Required	Description
args		Yes

setContainer

Add an HTMLElement as the new container for the interactor. All events will be bound to this new container.

container will gain the tabIndex=0 attribute to catch keyboard events. container must have focus (manually via click or tab, or programmatically via .focus()) to receive keypress events Outline on focus can be customized with CSS :focus pseudo-class.

Any old container will be removed along with its listeners.

setCurrentRenderer

Manually sets the current renderer.

Argument	Type	Required	Description

Set the desired update rate.

Argument	Type	Required	Description
desiredUpdateRate		Yes

External switching between joystick/trackball/new? modes.

style		Yes

setLightFollowCamera

Turn on/off the automatic repositioning of lights as the camera moves.

Argument	Type	Required	Description

Allow system to bypass scrolling debounce. This function must be called to allow the debounce to be bypassed

Argument	Type	Required	Description

Set the object used to perform pick operations.

Argument	Type	Required	Description
picker		Yes

setPreventDefaultOnPointerDown

Set whether preventDefault is called on pointer down.

Argument	Type	Required	Description
preventDefault	Boolean	Yes

setPreventDefaultOnPointerUp

Set whether preventDefault is called on pointer up.

If pointerup occurs without a preceeding pointerdown, then this does nothing.

stillUpdateRate		Yes

setView

Argument	Type	Required	Description
val		Yes

start
