Detailed Description

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.

Warning

vtkRenderWindowInteractor routes events through VTK's command/observer design pattern. That is, when vtkRenderWindowInteractor (actually, one of its subclasses) sees a platform-dependent event, it translates this into a VTK event using the InvokeEvent() method. Then any vtkInteractorObservers registered for that event are expected to respond as appropriate.

CreateTimer()

virtual int vtkRenderWindowInteractor::CreateTimer ( int  timerType )

virtual

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.

SetAltKey()

virtual void vtkRenderWindowInteractor::SetAltKey ( int  )

virtual

SetKeyCode()

virtual void vtkRenderWindowInteractor::SetKeyCode ( char  )

virtual

Set/get the unicode value for the key that was pressed, as an 8-bit char value.

This restricts the value to the Basic Latin and Latin1 blocks of unicode.

Since the 'char' type may be signed, one should cast to 'unsigned char' before retrieving the code value.

unsigned char keyCode = static_cast<unsigned char>(rwi->GetKeyCode())

Please note KeyCode is impacted by modifiers:

"A" -> 'a' "Shift" + "A" -> 'A' "Ctrl" + "A" -> 1 "Alt" + "A" -> 'a'

The behavior with Control modifier is related to C0 and C1 control codes.

Please note KeyCode IS NOT reliable across platforms, especially for special characters with modifiers. Using KeySym should be more reliable.

Default is 0.

This is the key symbol as defined by the relevant X headers (xlib/X11/keysymdef.h). On X based platforms this corresponds to the installed X server, whereas on other platforms the native key codes are translated into a string representation using VTK defined tables.

Please note the KeySym is impacted by modifiers:

"A" -> "a" "Shift" + "A" -> "A" "Alt" + "A" -> "a" "Ctrl" + "A" -> "a"

Please note KeySym may NOT be fully reliable across platforms, especially for special characters with modifiers. Please check the actual KeySym on supported platform before relying on it. However, KeySym is intended to always correspond to the key the user intended to press, even accross layouts and platforms.

Default is nullptr.

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.)

InteractorManagesTheEventLoop

bool vtkRenderWindowInteractor::InteractorManagesTheEventLoop

static

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:

1. If your app has an 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.
2. If your app does not have an int main entry point, disable this behavior. Otherwise, the webassembly application will not start up successfully.
