I would like to know if there is some special issue in using vtkPlaneWidget
with QVTKWidget. I have tested two identical codes, one using the standard
vtkRenderWindowInteractor outside a Qt environment, the other using
QVTKWidget. In both cases, I probe my dataset using vtkProbeFilter.
In the second case, I invoke the method vtkPlaneWidget::SetInteractor()
passing QVTKWidget::GetInteractor() as argument. The problem is that the
probing plane is not displayed. I see vtkPlaneWidget's manipulators, I
rotate the widget etc, but the plane used to probe my data is shown in
black. The same application yelds a normal behavior when using
What is the problem? I know that the call QVTKWidget::GetInteractor()
returns a QVTKInteractor object (which inherits vtkRenderWindowInteractor).
Do I have to give some special treatment to the vtkPlaneWidget in this case?
Many thanks for your help
