Hi Cory,<br>
<br>
thanks a lot! I was missing the import statements. Now it works fine.<br>
And I will remember the big Apply button :-).<br>

Hi Ian,<br>
<br>
I'm glad to hear you are interested in the Python View.<br>
<br>
I want to try out the python view for the first time, but I am not<br>
getting anywhere. I have created a python view and defined the<br>
functions setup_data and render. I tried the example script from the<br>
Kitware Blog (<a href="http://www.kitware.com/blog/__home/post/588" target="_blank">http://www.kitware.com/blog/__home/post/588</a><br>
<<a href="http://www.kitware.com/blog/home/post/588" target="_blank">http://www.kitware.com/blog/home/post/588</a>>), and I do get the<br>
memory size in the output messages, but the python view stays all<br>
black (no plot, no axes, nothing). Am I just missing something?<br>
I am using ParaView 4.3.1 64-bit Windows binaries.<br>
<br>
<br>
Did you copy and paste the script examples into the "Script" window, or<br>
did you load the example state file on the blog? I suggest loading the<br>
state file because the script examples in the blog post are missing some<br>
imports that are needed. The state file has the complete script - I just<br>
confirmed that it works on the 4.3.1 64-bit Windows binaries. You will<br>
have to point ParaView to the bluntfin.vts file when you load the state<br>
file, which you can download from<br>
<br>
<a href="http://www.paraview.org/gitweb?p=ParaViewData.git;a=blob_plain;f=Data/bluntfin.vts;hb=1fa9dce1c623e2d467c44b5337ba3a8378a6a537" target="_blank">http://www.paraview.org/gitweb?p=ParaViewData.git;a=blob_plain;f=Data/bluntfin.vts;hb=1fa9dce1c623e2d467c44b5337ba3a8378a6a537</a><br>
<br>
<br>
<br>
Besides, I find it a little confusing, that I do not really know,<br>
when the script is executed. What about something like an 'Apply'<br>
button?<br>
<br>
<br>
The Script is an auto-update property of the Python View. As such, it is<br>
executed any time the view needs to re-render. This includes any time<br>
you edit the script and then click elsewhere in the GUI, resize the<br>
ParaView window, etc. It should work to click on the Python View after<br>
you have edited the script - think of it as a big Apply button :-)<br>
<br>
Thanks,<br>
Cory<br>
<br>
<br>
Kind regards<br>
Ian<br>
