Detailed Description

Handles user interaction in web browsers.

The interactor intercepts user interaction events from a HTML page in a web browser and sends them to VTK using the Emscripten HTML5 C API.

Contrary to the documentation of Start, this interactor's event loop can be configured to not block in order to return control to the browser so that it can render graphics, UI, etc. See https://emscripten.org/docs/api_reference/emscripten.h.html#c.emscripten_set_main_loop See vtkRenderWindowInteractor::InteractorManagesTheEventLoop

Events:
vtkCommand::CharEvent vtkCommand::ExitEvent vtkCommand::KeyPressEvent vtkCommand::KeyReleaseEvent vtkCommand::MouseMoveEvent vtkCommand::TimerEvent

Member Function Documentation

◆ New()

static vtkWebAssemblyRenderWindowInteractor * vtkWebAssemblyRenderWindowInteractor::New ( )
static

Construct object so that light follows camera motion.

◆ IsTypeOf()

static vtkTypeBool vtkWebAssemblyRenderWindowInteractor::IsTypeOf ( const char *  type)
static

◆ IsA()

virtual vtkTypeBool vtkWebAssemblyRenderWindowInteractor::IsA ( const char *  name)
virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkRenderWindowInteractor.

◆ PrintSelf()

void vtkWebAssemblyRenderWindowInteractor::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkRenderWindowInteractor.

◆ Initialize()

void vtkWebAssemblyRenderWindowInteractor::Initialize ( )
overridevirtual

Initialize the event handler.

Reimplemented from vtkRenderWindowInteractor.

◆ ProcessEvents()

void vtkWebAssemblyRenderWindowInteractor::ProcessEvents ( )
overridevirtual

Process all user-interaction, timer events and return.

If there are no events, this method returns immediately.

Reimplemented from vtkRenderWindowInteractor.

◆ TerminateApp()

void vtkWebAssemblyRenderWindowInteractor::TerminateApp ( )
overridevirtual

This function is called on 'q','e' keypress if exitmethod is not specified and should be overridden by platform dependent subclasses to provide a termination procedure if one is required.

Reimplemented from vtkRenderWindowInteractor.

◆ ExitCallback()

void vtkWebAssemblyRenderWindowInteractor::ExitCallback ( )
overridevirtual

These methods correspond to the Exit, User and Pick callbacks.

They allow for the Style to invoke them.

Reimplemented from vtkRenderWindowInteractor.

◆ GetCanvasId()

virtual char * vtkWebAssemblyRenderWindowInteractor::GetCanvasId ( )
virtual

Specify the selector of the canvas element in the DOM.

◆ SetCanvasId()

virtual void vtkWebAssemblyRenderWindowInteractor::SetCanvasId ( const char *  )
virtual

◆ GetExpandCanvasToContainer()

virtual bool vtkWebAssemblyRenderWindowInteractor::GetExpandCanvasToContainer ( )
virtual

When true (default), the style of the parent element of canvas will be adjusted allowing the canvas to take up entire space of the parent.

◆ SetExpandCanvasToContainer()

virtual void vtkWebAssemblyRenderWindowInteractor::SetExpandCanvasToContainer ( bool  )
virtual

◆ ExpandCanvasToContainerOn()

virtual void vtkWebAssemblyRenderWindowInteractor::ExpandCanvasToContainerOn ( )
virtual

◆ ExpandCanvasToContainerOff()

virtual void vtkWebAssemblyRenderWindowInteractor::ExpandCanvasToContainerOff ( )
virtual

◆ GetInstallHTMLResizeObserver()

virtual bool vtkWebAssemblyRenderWindowInteractor::GetInstallHTMLResizeObserver ( )
virtual

When true (default), a JavaScript ResizeObserver is installed on the parent element of the canvas.

The observer shall adjust the width and height of the canvas element according the dimensions of the parent element.

◆ SetInstallHTMLResizeObserver()

virtual void vtkWebAssemblyRenderWindowInteractor::SetInstallHTMLResizeObserver ( bool  )

◆ InternalCreateTimer()

int vtkWebAssemblyRenderWindowInteractor::InternalCreateTimer ( int  timerId,
int  timerType,
unsigned long  duration 
)
overrideprotectedvirtual

Internal methods for creating and destroying timers that must be implemented by subclasses.

InternalCreateTimer() returns a platform-specific timerId and InternalDestroyTimer() returns non-zero value on success.

Reimplemented from vtkRenderWindowInteractor.

◆ InternalDestroyTimer()

int vtkWebAssemblyRenderWindowInteractor::InternalDestroyTimer ( int  platformTimerId)
overrideprotectedvirtual

Internal methods for creating and destroying timers that must be implemented by subclasses.

InternalCreateTimer() returns a platform-specific timerId and InternalDestroyTimer() returns non-zero value on success.

Reimplemented from vtkRenderWindowInteractor.

◆ StartEventLoop()

void vtkWebAssemblyRenderWindowInteractor::StartEventLoop ( )
overrideprotectedvirtual

This will start up the event loop without blocking the main thread.
