[Paraview] Scripting Paraview.

[shawn mckenzie]

Not sure if this is what you need....

# If you want the currently selected object in the menu
set currentlyViewedObject [[$application GetMainWindow] GetCurrentPVSource]

# Or loop through all menu objects applying your pipeline
set sources [[$application GetMainWindow] GetSourceList Sources]
set num [$sources GetNumberOfItems]

for {set i 0} {$i < $num} {incr i} {
     set eachObject [$sources GetItemAsObject $i]

     # run your pipeline on the eachObject obtained from the list
}
