Hi David,<br>In your vtkImageCamera.h, the line<br><br>   vtkTypeRevisionMacro(vtkImageCamera,vtkObject);<br><br>effectively tells that vtkImageCamera &quot;is a&quot; vtkObject!<br><br>You should use<br>   vtkTypeRevisionMacro(vtkImageCamera,vtkPhysicalCamera)<br>
instead<br><br>HTH,<br>Jerome<br><br><br><div class="gmail_quote">2009/12/2 David Doria <span dir="ltr">&lt;<a href="mailto:daviddoria%2Bvtk@gmail.com">daviddoria+vtk@gmail.com</a>&gt;</span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
I have 2 classes, vtkImageCamera that inherits from vtkPhysicalCamera -<br>
<br>
class vtkImageCamera : public vtkPhysicalCamera<br>
<br>
The PrintSelf function of the derived class is:<br>
<br>
void vtkImageCamera::PrintSelf(ostream&amp; os, vtkIndent indent)<br>
{<br>
  this-&gt;Superclass::PrintSelf(os,indent);<br>
  os &lt;&lt; &quot;new info here.&quot;;<br>
}<br>
<br>
When I output the derived class, I&#39;d expect it to first call PrintSelf<br>
of vtkPhysicalCamera. However, the vtkImageCamera::PrintSelf thinks<br>
the Superclass is vtkObject and it never calls<br>
vtkPhysicalCamera::PrintSelf.<br>
<br>
The output of:<br>
vtkstd::cout &lt;&lt; &quot;ImageCamera Superclass: &quot; &lt;&lt;<br>
this-&gt;Superclass::GetClassName() &lt;&lt; vtkstd::endl;<br>
<br>
is<br>
ImageCamera Superclass: vtkImageCamera<br>
<br>
Is there something that needs to be done manually to set the<br>
SuperClass variable to vtkPhysicalCamera?<br>
The vtkObject::PrintSelf function is called, but it skips the<br>
vtkPhysicalCamera::PrintSelf.<br>
<br>
Here is an extracted example of the problem:<br>

Thanks,<br>
