[Paraview] How to change the Representation within a Plugin ?

[Christian Richter]

Hi,





In Pythion I used:
        xreader=liggghts_Reader(guiName="liggghts_dump")
        xreader.FileNames=files
        SetDisplayProperties(xreader, Representation="Point Sprite")
        DataRepresentation1 = Show()
        DataRepresentation1.PointSpriteDefaultsInitialized = 1
        DataRepresentation1.Texture = []
        DataRepresentation1.RadiusTransferFunctionEnabled = 1
        DataRepresentation1.RadiusMode = 'Scalar'
        DataRepresentation1.Representation = 'Point Sprite'
        DataRepresentation1.RadiusArray = [None, 'radius']
        DataRepresentation1.RadiusIsProportional = 1

And I tried this in my C++Plugin:
    src = builder->createReader(QString("sources"),type, files, s); //works
    src->rename(type);

    pqActiveView& myActiveView=pqActiveView::instance();
    this->RenderView=myActiveView.current();


but get segfault at last line because repr is still NULL.
I attached the code and here is a video where you can see the Plugin working.

I've written a Plugin to use Paraview as "LiveView" for our simulation Data. With a QFileSystemWatcher the Plugin updates the filenames of the fileseries-reader everytime a new result-file was written to disk. Now I want to change the Representation from Point to Point Sprite automaticly after the source is created and set some standard properties. pqDataRepresentation *repr = builder->createDataRepresentation(src->getOutputPort(0), this->RenderView); vtkSMPropertyHelper(repr->getProxy(),"Representation").Set("Point Sprite"); //segfault
