Detailed Description

Integrates into the VTK event mechanism to generate MITK-specific events.

This class is the non-Qt-dependent counterpart to the event handling code in QmitkRenderWindow. It observes VTK interactor events and translates them into MITK interaction events via VtkEventAdapter.

Member Function Documentation

◆ AddInteractionEvent()

void mitk::vtkEventProvider::AddInteractionEvent ( unsigned long  ievent)
protected

Add a VTK event type to the list of observed interaction events.

Parameters
[in]ieventThe VTK event identifier to observe.

◆ GetRenderWindow()

mitk::RenderWindow* mitk::vtkEventProvider::GetRenderWindow ( )

Return the associated MITK RenderWindow.

Returns
Pointer to the MITK render window.

◆ ProcessEvents()

static void mitk::vtkEventProvider::ProcessEvents ( vtkObject *  object,
unsigned long  event,
void *  clientdata,
void *  calldata 
)
staticprotected

Callback for the VTK observer/command pattern.

Translates VTK events into MITK interaction events and forwards them to the associated RenderWindow.

◆ RemoveInteractionEvent()

void mitk::vtkEventProvider::RemoveInteractionEvent ( unsigned long  ievent)
protected

Remove a VTK event type from the list of observed interaction events.

Parameters
[in]ieventThe VTK event identifier to stop observing.

◆ SetEnabled()

void mitk::vtkEventProvider::SetEnabled ( int  enabled)
override

Enable or disable listening for VTK events.

When enabling, registers observers for all interaction event types. When disabling, removes all observers from the interactor.

Parameters
[in]enabledNon-zero to enable, zero to disable.

◆ SetInteractor()

void mitk::vtkEventProvider::SetInteractor ( vtkRenderWindowInteractor *  iren)
override

Set the VTK render window interactor.

If an interactor was previously set, it is disabled first.

Parameters
[in]irenThe new render window interactor.

◆ SetMitkRenderWindow()

virtual void mitk::vtkEventProvider::SetMitkRenderWindow ( mitk::RenderWindow *  renWin)
virtual

Set the MITK RenderWindow associated with this event provider.

Parameters
[in]renWinThe MITK render window to associate.
