Hello,<br><br> I am trying to use the vtkPointWidget as a probe so I can get the position/point ID's of a specific region so that I can use those points as seed points later on in the pipeline. The problem is that the vtkPointWidget has little example in C++ and the doxygen page is not much use. I have placed the widget into my code but then I get this error:<br>
<br> ERROR: In /home/hetrld/Project/VTK/Widgets/vtk3DWidget.cxx, line 74<br> vtkPointWidget (0x268e140): No input or prop defined for widget placement<br><br><br>On the doxygen page, I am told only to set the interactor to my current interactor (which I have conveniently named iren like many of the examples). I have done this and still get that error. I looked at the python example and tried to pass in some data to the widget with either the method SetInputData or SetInputConnection but neither of these actually exist in the vtkPointWidget. Does anyone have any experience with this probing widget that could help me figure out how to use it?<br>
