[vtkusers] VTK Button event of interactor

[Lodron, Gerald]

 Hi,

 Can i simulate a button press command for the vtkRendererWindowInteractor
 class? I dont know why but my interactor starts in the joystick mode and i
 want the trackball mode which is switched with the button "t". Does anyone
 know how to swith into trackball mode in code (maybe a little bit more
 confortable than invoking a button press event)?
 

Best regards
