[vtkusers] VTK updating (qvtkWidget)

[M. Jordan]

In render some things in the constructor of my GUI.

Now I try to add some spheres and update/redraw the radius of the spheres every second.
I have a text file containing the new radius of each sphere and a timer to generate the events.

When I am changing a radius in the .txt file (while my program is executed) to a higher value, the sphere grows in real time.
But when I decrease the radius, the sphere isn't decreasing.

I think that my program doesn't update everything.


I use:
ui.qvtkWidget->update();


In my timer function everything (expect the renderer and renderwindow) is created each time.

So I can't figure out whats the problem.
