[Paraview] [Paraview-developers] The Quest for Data

[Eric E. Monson]

Hey Utkarsh,

That works great -- thanks!

Is there an important reason for the Find Data dialog to be modal? I find myself wanting to interact with the render window to see the positions of the selected points, but I'm locked out, and then it's annoying because if I close the dialog and then want to modify my query/selection, I have to re-choose Point data and enter everything again. Is it just that if someone went and changed the selection through another mechanism, then came back to the dialog, the query wouldn't be valid any more?

Thanks again,
-Eric
