How to use vtkAxesTransformWidget to generate 3D widget in VTK scene ?

Hi, I just want to generate a widget around an 3D actor, then I interact with the widget to move, rotate, scale the actor or bind other event. The official method is use vtkAxesTransformWidget and vtkAxesTransformRepresentation, but I failed to generate it with "ERROR: In D:\02_Data\vtk\Rendering\FreeType\vtkVectorText.cxx, line 63
vtkVectorText (00000203298F2110): Text is not set!

ERROR: In D:\02_Data\vtk\Common\ExecutionModel\vtkExecutive.cxx, line 753

I meet the same problem. I look into the code of vtkAxesTransformWidget and think the code is not finished.

Need someone to fix?

Still see this error, is there a different widget available to manipulate the Actor for Translation and rotation? like a move tool?

Thanks!

We had lots of issues with the stock VTK widgets in 3D Slicer and we ended up adding a new widget for translating/rotating/scaling objects in 3D and slice views. We have just announced the feature here. If you want to render with VTK (especially in the domain of medical imaging) and want to interactively transform objects then you can use this widget in 3D Slicer.
