[vtkusers] strange behaviour when using vtkInteractorStyleTrackballActor and vtkBalloonWidget

[diego0020]

Hello

I have some new information:

- The problem also occurs with vtkInteractorStyleTrackballCamera
- It gets really extreme when inside a tkinter widget.

I attach a new example code. I would appreciate any ideas as it is starting
to get annoying. We have several applications which use tkinter for
interface and vtk for visualization, and we would really like to use the
balloon widget.

Best regards
Diego

import vtk
import Tkinter as tk

from vtk.tk.vtkTkRenderWindowInteractor import \
     vtkTkRenderWindowInteractor

root=tk.Tk()

renWin=vtk.vtkRenderWindow()
renderer=vtk.vtkRenderer()
renWin.AddRenderer(renderer)
render_widget = vtkTkRenderWindowInteractor(root,
                                            rw=renWin, width=600,
                                            height=600)
render_widget.pack(fill='both',expand=True)
iact=render_widget.GetRenderWindow().GetInteractor()
iact.SetInteractorStyle(vtk.vtkInteractorStyleTrackballCamera())
iact.SetRenderWindow(renWin)

balloon_w=vtk.vtkBalloonWidget()
balloon_w.SetInteractor(iact)
balloon_r=vtk.vtkBalloonRepresentation()
balloon_w.SetRepresentation(balloon_r)
balloon_w.On()

cone=vtk.vtkConeSource()
cone_map=vtk.vtkPolyDataMapper()
cone_map.SetInputConnection(cone.GetOutputPort())
cone_act=vtk.vtkActor()
cone_act.SetMapper(cone_map)

renderer.AddViewProp(cone_act)
balloon_w.AddBalloon(cone_act,"Cone" )
renderer.ResetCamera()
renWin.Initialize()
iact.Initialize()
root.mainloop()
