platform-independent render window interaction including picking and frame rate control.
vtkRenderWindowInteractor provides a platform-independent interaction mechanism for mouse/key/time events. It serves as a base class for platform-dependent implementations that handle routing of mouse/key/timer messages to vtkInteractorObserver and its subclasses. vtkRenderWindowInteractor also provides controls for picking, rendering frame rate, and headlights.
vtkRenderWindowInteractor has changed from previous implementations and now serves only as a shell 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.

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.

This class provides two groups of methods for manipulating timers.
The first group (CreateTimer(timerType) and DestroyTimer()) implicitly use an internal timer id (and are present for backward compatibility). The second group (CreateRepeatingTimer(long),CreateOneShotTimer(long), ResetTimer(int),DestroyTimer(int)) use timer ids so multiple timers can be independently managed. In the first group, the CreateTimer() method takes an argument indicating whether the timer is created the first time (timerType==VTKI_TIMER_FIRST) or whether it is being reset (timerType==VTKI_TIMER_UPDATE). (In initial implementations of VTK this was how one shot and repeating timers were managed.) In the second group, the create methods take a timer duration argument (in milliseconds) and return a timer id. Thus the ResetTimer(timerId) and DestroyTimer(timerId) methods take this timer id and operate on the timer as appropriate. Make sure you run Initialize() before creating the timer in order for it to work.

int vtkRenderWindowInteractor::CreateRepeatingTimer | ( | unsigned long | duration | ) |

int vtkRenderWindowInteractor::CreateOneShotTimer | ( | unsigned long | duration | ) |

int vtkRenderWindowInteractor::IsOneShotTimer | ( | int | timerId | ) |
Query whether the specified timerId is a one shot timer.
unsigned long vtkRenderWindowInteractor::GetTimerDuration | ( | int | timerId | ) |
Get the duration (in milliseconds) for the specified timerId.
int vtkRenderWindowInteractor::ResetTimer | ( | int | timerId | ) |

Care must be taken when adjusting the timer interval from the default value of 10 milliseconds–it may adversely affect the interactors.

These methods are used to communicate information about the currently firing CreateTimerEvent or DestroyTimerEvent.
The caller of CreateTimerEvent sets up TimerEventId, TimerEventType and TimerEventDuration. The observer of CreateTimerEvent should set up an appropriate platform specific timer based on those values and set the TimerEventPlatformId before returning. The caller of DestroyTimerEvent sets up TimerEventPlatformId. The observer of DestroyTimerEvent should simply destroy the platform specific timer created by CreateTimerEvent. See vtkGenericRenderWindowInteractor's InternalCreateTimer and InternalDestroyTimer for an example.

This methods sets the Size ivar of the interactor without actually changing the size of the window.
Normally application programmers would use UpdateSize if anything. This is useful for letting someone else change the size of the rendering window and just letting the interactor know about the change. The current event width/height (if any) is in EventSize (Expose event, for example). Window size is measured in pixels.

When an event occurs, we must determine which Renderer the event occurred within, since one RenderWindow may contain multiple renderers.
vtkObserverMediator * vtkRenderWindowInteractor::GetObserverMediator | ( | ) |
Return the object used to mediate between vtkInteractorObservers contending for resources.
Multiple interactor observers will often request different resources (e.g., cursor shape); the mediator uses a strategy to provide the resource based on priority of the observer plus the particular request (default versus non-default cursor shape).

When handling gestures you can query this value to determine how many pointers are down for the gesture this is useful for pan gestures for example.
void vtkRenderWindowInteractor::ClearContact | ( | size_t | contactID | ) |
Most multitouch systems use persistent contact/pointer ids to track events/motion during multitouch events.
We keep an array that maps these system dependent contact ids to our pointer index These functions return -1 if the ID is not found or if there is no more room for contacts

These methods allow the interactor to control which events are processed.
When the GrabFocus() method is called, then only events that the supplied vtkCommands have registered are invoked. (This method is typically used by widgets, i.e., subclasses of vtkInteractorObserver, to grab events once an event sequence begins.) Note that the friend declaration is done here to avoid doing so in the superclass vtkObject.

This flag is useful when you are integrating VTK in a larger system.
In such cases, an application can lock up if the Start()
method in vtkRenderWindowInteractor processes events indefinitely without giving the system a chance to execute anything. The default value for this flag is true. It currently only affects VTK webassembly applications.
As an example with webassembly in the browser through emscripten SDK:
int main
entry point, leave this value enabled. Emscripten will simulate an infinite event loop and avoid running code after interactor->Start()
which is usually the end of main
. Otherwise, all VTK objects will go out of scope immediately without giving a chance for user interaction with the render window.int main
entry point, disable this behavior. Otherwise, the webassembly application will not start up successfully. Definition at line 980 of file vtkRenderWindowInteractor.h.
