No, the DebugLeakReport appears when i close the application. Therefore i<br>
just include the vtkDebugLeaks.h<br>
<br>
the method that instantiates and delete the surrounding class is called from<br>
from a combobox and the whole method is:<br>
<br>
void ImageCtrl::Init_3D(void)<br>
{<br>
ImageVolumeData *vtkModul = new ImageVolumeData();<br>
<br>
delete vtkModul;<br>
<br>
return;<br>
}<br>
<br>
The class ImageCtrl is derived from CCmdTarget and handles the<br>
Messagerouting in the program.<br>
<br>
I debugged thought the code and watched the ProcessExplorers<br>
PrivateByteHistory of the running programm. I did the same in the<br>
vtkexamples and there everything works fine. I know it sounds strange and<br>
obviously it is a mistake on my side.<br>
<br>
Does anybody has an idea<br>
