Hello,
this is likely very simple but I’ve decided to ask here after not being able to solve it. What I want to do is to mark an object in the pipeline browser as selected, given its pqPipelineSource pointer. I’m working inside the pqOpenVRControls class, where the reverse example of getting a pqPipelineSource\* based on selection already exists.
My approach looks somewhat like this:
> QItemSelectionModel\* smodel = this-\>Internals-\>pipelineBrowser-\>getSelectionModel();
> QModelIndex index = smodel-\>model()-\>index(0,0); //Tried a lot of stuff here
> const pqPipelineModel\* model = this-\>Internals-\>pipelineBrowser-\>getPipelineModel(index);
> QModelIndex selindex = model-\>getIndexFor(source); // source being the provided pqPipelineSource\*
> smodel-\>select(selindex, QItemSelectionModel::SelectionFlag::Select);
A common error I get is that I’m using a QModelIndex from a different model, but I’m not sure how to solve this.
Thank you in advance.

Hi,
You could just set you source as the active source (`pqActiveObjects::instance().setActiveSource(pqsource));`) and the pipeline widget will automatically set it as the active/selected pipeline source.
Best,
