[Paraview] Continous update from Timer events possible?

[Biddiscombe, John A.]

Just throw a QTimer onto a custom panel and trigger the active view to update when it times out. Providing the updates are happening inside the primary GUI thread, all should be well.

Subject: [Paraview] Continous update from Timer events possible?

Dear all,
is it possible to update Paraview visualizations a few times per second, 
reacting to Timer Events?

We have sensor data arriving over a network stream, which are processed and then 
to be visualized as glyph properties. Currently we use a very simple VTK 
application which checks for new data every 500ms and updates the rendering if 
necessary. We would like to integrate this View in Paraview.

I had a look at the "Time in ParaView" tutorial, but my impression is that the 
Time variable is not useful in our case, because it assumes datasets to be 
defined at several time steps, whereas we always have a single (changing) 
dataset representing "current time". Does an example exist how to write a 
Paraview plugin which updates itself in regular intervals?

Best wishes
Ulrich
