<div>Hi all,</div><div><br></div><div>I have created a vtk render window and I want to change the data in the window each time user select an option from a set of radio buttons in a MFC window.</div><div>To do this I called vtkrender window each time an option is selected. </div>
<div>This is working fine, but when I tried to close the vtk window. I get a debug assertion from vtkgarbagecollector saying that object->getreferencecount == 1.</div><div><br></div><div>Below is the code I am using to render vtk window.</div>
