Paraview Lite change default representation

I have just tried with Linux with no luck

I think I know why… You’ve loaded a file, not created a source. I did not patch the file loading… Just any proxy creation.

Try to create a “Cone”.

23

If you want to do it at file loading, that will be the method to override as well https://github.com/Kitware/ParaView/blob/master/Web/Python/paraview/web/protocols.py#L2808-L2809

Hi Sebastien,

We are hitting the right key now.

I got a trace in this overloaded pv.proxy.manager.create.reader

however I got an error when trying to call the original code:

@exportRpc(“pv.proxy.manager.create.reader”)

def customOpen(self, relativePath):

    """

    Open relative file paths, attempting to use the file extension to select

    from the configured readers.

    """

    print('custom open')

    response = self.pxm.reader(relativePath)
    #response = self.pxm.create.reader(relativePath)

    rep = simple.Show()

    rep.Representation = 'Surface With Edges'

    self.getApplication().InvokeEvent('UpdateEvent')

    return response

both attemps fail with:

  }
}

How do I properly call the original code?

Thanks,

The method name is open so you should use that name.

response = self.pxm.open(relativePath)

It was given to you in my previous link
