Hi Utkarsh,
these are great news. I tried the python trace but not in combination
with the extraction (what I acutally do need anyway....)
As you might remember I am working around the "lack" of possibilty to
select whole objects (cells with same RegionID). With the given
SelectionQuerySource this workaround is complete.
There remains one issue: At some point I call an ExtractSelection() in
Python that is followed by a call to a vtk-Plugin (which writes the
point data of the selected points to disk). The resulting file is empty,
because the Extraction takes a few seconds and obviously the plugin has
no valid input when being executed. Paraview also crashes as a
consequence. When I am doing this manually (trigger ExtractSelection,
wait until it's done, call the vtk Plugin to write the point data)
everything works fine. I could just go ahead and do a dull time.sleep(3)
between the extraction and the call to the plugin, but this certainly
isn't good programming style.
What can I do instead?
Best regards,
Christian

Yes, you can use the "SelectionQuerySource" to construct your query as follows:
selection_source_540 = SelectionQuerySource( InsideOut=0,
ArrayName='', HierarchicalLevel=-1, ProcessID=-1, ContainingCells=0,
DoubleValues=None, HierarchicalIndex=-1, FieldType='CELL',
ArrayComponent=0, Operator='IS_ONE_OF', TermMode='ID',
CompositeIndex=-1, IdTypeValues=0 )
You can use the python trace recorder functionality to determine how
to create the query. You will, however have to "Extract Selection"
from the query (and hit apply) before the selection_source object will
appear in the trace.

Hello!
Is there any chance that the new Edit->Find Data functionality is available
in Python-Scripting?
Best regards,
