[vtkusers] How to delete an interactorstyle in runtime?

[sercani]

Hi David;
This is the declaration of cis:
/CustomInteractorStyle *cis=CustomInteractorStyle::New();/

and this is the definiton of CustomInteractorStyle class:
/
class CustomInteractorStyle : public QObject, public vtkInteractorStyleImage
{
};/
  this class contains virtual mouse functions of vtkInteractorStyleImage 
and handles these events according to my software's tools...When another 
tool selected, it'is own custom style is set to interactor's style and 
handles events too...When i set the interactor style in runtime like this:

/vtkImageViewer2 viewer;
viewer->GetRenderWindow()->GetInteractor()->SetInteractorStyle(cis);/
  it throws an
"/Unhandled exception at 0x60772abb (vtkRendering.dll) in VTKTry.exe: 
0xC0000005: Access violation reading location 0x00000050.
The program '[2568] VTKTry.exe: Native' has exited with code -1073741819 
(0xc0000005)/."

If i don't set the interactor's interactorstyle,but set the 
interactorstyle's interactor like this:
/cis->SetInteractor(viewer->GetRenderWindow()->GetInteractor());/  
QVTKWidget and my vtkImageViewer2 handles the mousewheel event 
seperately and this cause wrong behaviour in my program...
  I am setting the viewer's and QVTKWidget's interactor like this:
/
     vtkImageViewer2 viewer=vtkImageViewer2::New();
     qvtk->SetRenderWindow(viewer->GetRenderWindow());
     vtkRenderWindowInteractor *interactor=vtkRenderWindowInteractor::New();
     viewer->GetRenderWindow()->SetInteractor(interactor);
     
qvtk->GetRenderWindow()->SetInteractor(viewer->GetRenderWindow()->GetInteractor());/

How can i solve these problems?
