[Paraview] help with a simple script?

[Celia Bremer]

Seb,

When I say that the OpenGL window freezes, I mean the window is unresponsive in that I can't minimize it, and Windows task manager says "Not Responding". There's nothing in the window except for the purple background, even when there should be something, e.g. if I did Show(o) before calling Render(), where o is one of the pipeline objects.

The thing I called layout windows, and I suppose it's really called something else (view layouts?), happens when I run the script from the Python shell that comes with the GUI. I'm referring to the tabs, "Layout #1", "Layout #2", etc. Here:

>>> paraview version 3.14.1, Date: 2012-02-17
from paraview.simple import *
>>> GetLayouts()
{('ViewLayout1', '275'): <paraview.servermanager.ViewLayout object at 0x0000000010FB4748>}
>>> servermanager.LoadState("testpipeline.pvsm")
>>> GetLayouts()
{('ViewLayout1', '275'): <paraview.servermanager.ViewLayout object at 0x0000000010FB4748>, ('ViewLayout5', '2353'): <paraview.servermanager.ViewLayout object at 0x0000000010FB47B8>}
>>> servermanager.LoadState("testpipeline.pvsm")
>>> GetLayouts()
{('ViewLayout1', '275'): <paraview.servermanager.ViewLayout object at 0x0000000010FB4748>, ('ViewLayout5', '3972'): <paraview.servermanager.ViewLayout object at 0x0000000012EC3240>, ('ViewLayout5', '2353'): <paraview.servermanager.ViewLayout object at 0x0000000010FB47B8>}

This happens even if I use an empty state file, i.e. what I get when I open Paraview GUI, save state, save as empty.pvsm. If I load this state from the GUI, it opens in the original layout window, ViewLayout1, without any craziness. If I open it from the shell as above, the first tab splits into 2 views, the right view looks all weird (attached), a new tab opens and the state file is loaded into a second tab. If I load the state file again, then the second tab splits like the first (and if there was any content, it stays on the left hand side), a third tab opens, and the content shows up in the third tab. And so on. The names of these new tabs depend on the state file (above: 1 5 5, it might be 3 1 3 3, or if I use an empty state file, then it's 1 1 1 1), so I don't know what's the deal with that, but as long as I can close them before moving on to the next state file, I don't think it'll cause problems.
