Subject: Re: [Paraview] Why does this programmable source not work outside
the paraview GUI
The answer is simple: you are missing the UpdateVTKObjects() call to
'apply' the change to the property.
If you going to use ...GetProperty(..).SetElement(...) API then after
the property has been set, one must call proxy.UpdateVTKObjects().
so in your example:
...
pgsrc.GetProperty(Script).SetElement(0, ... )
pgsrc.UpdateVTKObjects()
Alternatively you can simply do:
pgsrc.Script = .
and then you don't have to worry about calling UpdateVTKObjects().

Hi All,
Why does this piece of code containing a programmable source not work
OUTSIDE the paraview GUI?
a) When the source is changed to ConeSource() it works (see Label 1 in
the code below).
b) Also when the Script content is pasted inside the paraview GUI
scripting editor, it does work - so the script contents itself is ok.
When the code is run directly from a python command line only an empty
graphis window is displayed - as if the script part is faulty.
Thanks in advance,
Louis
HERE IS THE EXAMPLE:

from paraview import servermanager
connection = servermanager.Connect()
pgsrc=servermanager.sources.ProgrammableSource()
pgsrc.GetProperty(Script).SetElement(0,
import vtk
pts=vtk.vtkPoints()
pts.Initialize()
pts.InsertNextPoint(0,0,0)
pts.InsertNextPoint(1,0,.0)
pts.InsertNextPoint(2,1,0)
pts.InsertNextPoint(3,3,0.)
cel=vtk.vtkCellArray()
cel.Initialize()
cel.InsertNextCell(4) # number of points
cel.InsertCellPoint(0)
cel.InsertCellPoint(1)
cel.InsertCellPoint(2)
cel.InsertCellPoint(3)
output = self.GetOutput()
output.SetPoints(pts)
output.SetStrips(cel)
)
view = servermanager.CreateRenderView()
# This programmable source pgsrc does not display
rep = servermanager.CreateRepresentation(pgsrc,view)
# Label 1: This source do display
#coneSource = servermanager.sources.ConeSource()
#rep = servermanager.CreateRepresentation(coneSource,view)
view.StillRender()
view.ResetCamera()
view.StillRender()
