[Paraview] Spreadsheet View and Selection - Bug

[Christian Werner]

That was fast...  :) It works like a charm now, but wasn't it possible 
to select distinct additional elements using the CTRL-key? At least 
that's a common feature in such an environment. On the other side I 
don't actually see a use for this ( at least for what I am doing ).

What is much more important for me: Is there a way to do this selection 
with a plane 2D image, i.e. selecting a Pixel ( or multiple ) in the 
image and get the appropriate cell highlighted in the spreadsheet? I 
have to execute some custom plugin filter with the value of a picked 
pixel. How I pass this value to this filter is another story but some 
picking would definetely be a good start. When I load a 2D image, all 
these selection buttons are greyed out...


Best regards,
Christian
