# Usage

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.

To create an instance of class vtkRenderWindowInteractor, simply invoke its constructor as follows

      obj = vtkRenderWindowInteractor

# Methods

The class vtkRenderWindowInteractor has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkRenderWindowInteractor class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkRenderWindowInteractor = obj.NewInstance ()`
- `vtkRenderWindowInteractor = obj.SafeDownCast (vtkObject o)`
- `obj.Initialize ()` - Prepare for handling events. This must be called before the interactor will work.
- `obj.ReInitialize ()` - This Method detects loops of RenderWindow-Interactor, so objects are freed properly.
- `obj.UnRegister (vtkObjectBase o)` - This Method detects loops of RenderWindow-Interactor, so objects are freed properly.
- `obj.Start ()` - 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.
- `obj.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.
- `obj.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.
- `int = obj.GetEnabled ()` - 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.
- `obj.EnableRenderOn ()` - Enable/Disable whether vtkRenderWindowInteractor::Render() calls this->RenderWindow->Render().
- `obj.EnableRenderOff ()` - Enable/Disable whether vtkRenderWindowInteractor::Render() calls this->RenderWindow->Render().
- `obj.SetEnableRender (bool )` - Enable/Disable whether vtkRenderWindowInteractor::Render() calls this->RenderWindow->Render().
- `bool = obj.GetEnableRender ()` - Enable/Disable whether vtkRenderWindowInteractor::Render() calls this->RenderWindow->Render().
- `obj.SetRenderWindow (vtkRenderWindow aren)` - Set/Get the rendering window being controlled by this object.
- `vtkRenderWindow = obj.GetRenderWindow ()` - Set/Get the rendering window being controlled by this object.
- `obj.UpdateSize (int x, int y)` - Event loop notification member for window size change. Window size is measured in pixels.
- `int = obj.CreateTimer (int timerType)` - 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. Methods are also available for determining

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.
- `obj.SetSize (int , int )` - 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.
- `obj.SetSize (int a[2])` - 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.
- `int = obj. GetSize ()` - 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.

- `vtkRenderer = obj.FindPokedRenderer (int , int )` - When an event occurs, we must determine which Renderer the event occurred within, since one RenderWindow may contain multiple renderers.
- `vtkObserverMediator = obj.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).
- `obj.SetUseTDx (bool )` - Use a 3DConnexion device. Initial value is false. If VTK is not build with the TDx option, this is no-op. If VTK is build with the TDx option, and a device is not connected, a warning is emitted. It is must be called before the first Render to be effective, otherwise it is ignored.
- `bool = obj.GetUseTDx ()` - Use a 3DConnexion device. Initial value is false. If VTK is not build with the TDx option, this is no-op. If VTK is build with the TDx option, and a device is not connected, a warning is emitted. It is must be called before the first Render to be effective, otherwise it is ignored.
