[Paraview-developers] Disabling a menu item in Paraview GUI

[Joachim Pouderoux]

Prashant,

I think you could track the number of objects available in the model,
something like :

  pqServerManagerModel* model =
    pqApplicationCore::instance()->getServerManagerModel();
  pqServer* server = pqApplicationCore::instance()->getActiveServer();
  QList<pqPipelineSource*> sources =
model->findItems<pqPipelineSource*>(server);
  int numberOfPipelineSources = sources.size();
  mymenu->setEnable(numberOfPipelineSources != 0);

Best,
Joachim
