Hot Link Python Script

Does anyone know of python script that activates hot-link mode between different windows/studies?

You’d just need to convert this code to python:

Slicer/Slicer/blob/master/Libs/MRML/Widgets/qMRMLSliceControllerWidget.cxx#L2077-L2094


//---------------------------------------------------------------------------
void qMRMLSliceControllerWidget::setHotLinked(bool linked)
{
  vtkCollection* sliceCompositeNodes = this->mrmlScene() ?
    this->mrmlScene()->GetNodesByClass("vtkMRMLSliceCompositeNode") : nullptr;
  if (!sliceCompositeNodes)
    {
    return;
    }
  vtkMRMLSliceCompositeNode* sliceCompositeNode = nullptr;
  for(sliceCompositeNodes->InitTraversal();
      (sliceCompositeNode = vtkMRMLSliceCompositeNode::SafeDownCast(
        sliceCompositeNodes->GetNextItemAsObject()));)
    {
    sliceCompositeNode->SetHotLinkedControl(linked);
    }
  sliceCompositeNodes->Delete();
}

it’ll be something like

compositeNodes = slicer.util.getNodesByClass('vtkMRMLSliceCompositeNode')
for node in compositeNodes:
  node.SetHotLinkedControl(linked)

Thanks for the help!

This will automatically turn on hot link for all views in Python:

compositeNodes = slicer.util.getNodesByClass('vtkMRMLSliceCompositeNode')
for node in compositeNodes:
  node.SetHotLinkedControl(1)
  node.SetLinkedControl(1)
