Thank you Utkarsh, thas does the trick. Can you give me a hint how I can do DataRepresentation1.RadiusArray = [None, 'radius'] //python trace in C++ ? Thanks, Christian
Zitat von Utkarsh Ayachit <utkarsh.ayac...@kitware.com>:
Try calling the following before src->updatePipeline() before attempting to create the representation. The reader hasn't been executed yet and hence it doesn't provide any information about what type of data it will produce and hence createDataRepresentation() cannot create any data-representation for it. updatePipeline() forces the reader to execute i.e. it's RequestData() will get called and then the rest should work as expected.

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. 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(); pqDataRepresentation *repr = builder->createDataRepresentation(src->getOutputPort(0), this->RenderView); vtkSMPropertyHelper(repr->getProxy(),"Representation").Set("Point Sprite"); //segfault 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. http://youtu.be/5CGGf-kPcEQ best, Christian _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://www.paraview.org/mailman/listinfo/paraview
