How to make a pop-up warning / error message?

Hello dear ParaView developers!

How can one pass errors from the custom client-side widgets to the user? For server-side there are vtk Error macros, however, they dont seem to work in the client side. What are the alternatives?

Thanks you a lot!

you can use qWarning in pq classes, and vtkLogF everywhere else, but vtkErrorMacro should work in client code.
