[Paraview] Paraviewweb

[Sebastien Jourdain]

Ok, I miss understood your goal.

Then, the missing part should be something like that.

var view = paraview.GetRenderView(); // this is optional if you
already have a reference to the view...
view.setInteractionMode(2);

Although, I've quickly tried it online with firebug and I did not
manage to see the selection. I'm wondering if we are both missing
something here... Like the creation of a selection proxy that is
created to get the selected screen area and convert it to a set of
cellId...

Utkarsh might have a better insight on that selection part.

PS: Here is the mapping based on the string values

file: ParaView-SRC/ParaViewCore/ServerImplementation/Resources/views_and_representations.xml

<IntVectorProperty name="InteractionMode"
       command="SetInteractionMode"
       number_of_elements="1"
       default_values="0">
       <EnumerationDomain name="enum">
         <Entry text="3D" value="0" />
         <Entry text="2D" value="1" />
         <Entry text="Selection" value="2" />
       </EnumerationDomain>
     </IntVectorProperty>
