[IGSTK-Developers] igstkAxesObject

[Julien Jomier]

Hi David,

Yes I saw that but didn't have time to investigate this more. I think we 
cannot modify the color of the vtkAxesActor and that is the problem.
For the moment I've disabled the test for SetProperty(). I'll try to 
investigate more this week unless someone wants to give it a try.

thanks,

Julien
