[vtkusers] deleting frame in vtk java frame

[Elhassan Abdou]

Hi all

I am using vtkresliceimageviewer which is inherited from vtkImageViewer2 to produce MPR. I succeeded to create the three vtkCanvas and render on them. 
The PROBLEM is there are another three old frames produced from the vtkResliceImageViewer and they are empty as the renderer of viewer now is directed to vtkcanvas. How i can delete them.

Below is the snippet of adding the viewers to the canvases;
imagestyle=new vtkInteractorStyleImage();
iren = sagitallCanvas.GetRenderWindow().GetInteractor();
iren.SetInteractorStyle(imagestyle);
sagittalViewer.SetRenderWindow(sagitallCanvas.GetRenderWindow());
sagittalViewer.SetRenderer(sagitallCanvas.GetRenderer());
//sagitallCanvas.GetRenderWindow().AddRenderer(sagittalViewer.GetRenderer());
sagittalViewer.SetupInteractor(iren);
//sagitallCanvas.GetRenderer().ResetCamera();
imagestyle=new vtkInteractorStyleImage();
iren = cronalCanvas.GetRenderWindow().GetInteractor();
iren.SetInteractorStyle(imagestyle);
cronalViewer.SetRenderWindow(cronalCanvas.GetRenderWindow());
cronalViewer.SetRenderer(cronalCanvas.GetRenderer());
//cronalCanvas.GetRenderWindow().AddRenderer(cronalViewer.GetRenderer());
cronalViewer.SetupInteractor(iren);
//cronalCanvas.GetRenderer().ResetCamera();

imagestyle=new vtkInteractorStyleImage();
iren = axialCanvas.GetRenderWindow().GetInteractor();
iren.SetInteractorStyle(imagestyle);
axialViewer.SetRenderWindow(axialCanvas.GetRenderWindow());
axialViewer.SetRenderer(axialCanvas.GetRenderer());
axialViewer.SetupInteractor(iren);

Best Regards
