[vtkusers] vtkTextActor problem

[Randy Heiland]

Would someone know why I am unable to display a vtkTextActor along with
a vtkTubeFilter?  For example, in the officeTubes.py (or .tcl) script
(Examples/VisualizationAlgorithms), if you insert:

textActor = vtk.vtkTextActor()
textActor.ScaledTextOn()
textActor.SetDisplayPosition(50, 50)
textActor.SetInput('sample text')

and
ren.AddActor(textActor)

the text is not rendered.  However, commenting out the tubes will
display the text:
#ren.AddActor(streamTubeActor)

I'm using the latest VTK from CVS.

thanks, Randy

for tcl:
vtkTextActor textActor
  textActor ScaledTextOn
  textActor SetDisplayPosition 50  50
  textActor SetInput "sample text"
ren1 AddActor textActor
