10.0pt;font-family:Arial;color:navy'>Yes the code runs on my machine, I am
using WinXP, Python 2.5 - vtk 5.4.0 (from pythonxy). I do not know much
about using timers since my first experience was yesterday, but I was able to
create a similar effect in python-vtk (5.0.4-1.1ubuntu) using the older CreateTimer,
DestroyTimer mechanism. The timer is created the first time with the
argument 0 (VTKXI_TIMER_FIRST) and reset in the callback function using 1 (VTKI_TIMER_UPDATE).
The duration of the timer is set by passing an argument when the vtkTimerCallback
class is initialized. As I mentioned, I am new at this so I am not sure
this is the best implementation, but this version seems to work with both vtk
5.4 and 5.0. <o:p></o:p></span></font></p>
