[Paraview] [EXT] Re: Stupid question on Programmable Source

[Dennis Conklin]

Utkarsh,

I got it working by making a list of pointers to vtk.vtkFloatArray

Attached is the version which gives me all 97 Element variables.

My other questions are:

1.  I really want this as a reader, that everyone can use.    Is there some way to have the user enter a filename which is more elegant than having them edit the script?   For instance, can the server-side xml plugin stuff be edited slightly to work with a Programmable source, so I could put in a text box for them to type the filename.    Even better would be a popup file browser, but I dream!

2.  I assume without compiling here that I cannot actually get this as a reader, correct?

Thanks for your interest.

Dennis

Dennis,

I always change the output type using the Output Type property on the Properties panel for the Programmable source. Then the "output" is indeed the type I expect it to be.

You don't need do this at all, I am sure this working only when the "Output Type" is set properly on the Properties panel. Just use the output variable provided to you in the Programamble Filters environment (similar to inputs, self, etc). In otherwords, if your script, just remove the output = self.... line :).
